使用到 Aspose.Cells 插件，整理一下。

一：新建解決方案，目錄如下

　　

　　目錄說明：

　　　　Program.cs - 入口類

　　　　ExcelGenerator.cs - Aspose.Cells 操作類

　　　　Aspose.Cell.dll - 基礎dll【文件見文章底部源代碼內】

　　　　License.lic -?Aspose.Cells 破解證書【文件見文章底部源代碼內】

　　　　　　ps：由于 Aspose.Cells 插件 是收費插件，需要在使用插件前，設置一下許可證，否則在生成的Excel 中 會出現一個名叫 Evaluation Warning 的 Sheet.如圖所示：

　　　　

二：Aspose.Cells 操作

　　2.1 引入?Aspose.Cell.dll?

　　

　　2.2 設置?Aspose.Cell.dll 證書?License.lic

　　　　2.2.1 設置證書。我一般都寫在生成Excel類的構造函數中了。文件路徑要和證書的位置保持一致

Excel.License l = new Excel.License(); l.SetLicense("Aid/License.lic");

　　　　2.2.2 修改證書屬性。在解決方案中，右擊?License.lic選擇屬性,修改?Copy to Ouput Directory 屬性為 Copy always

　　　　

　　2.3 打開現有Execl 模板

//模板文件路徑 string Template_File_Path = @".\Template\Template.xlsx";// 打開 Excel 模板 Workbook CurrentWorkbook = File.Exists(Template_File_Path) ? new Workbook(Template_File_Path) : new Workbook();// 打開第一個sheet Worksheet DetailSheet = CurrentWorkbook.Worksheets[0];

　　2.4 寫入數據

　　　　2.4.1 填寫數據到指定單元格

// 比如要在 A1 位置寫入 Demo這個值 Cell itemCell = DetailSheet.Cells["A1"];itemCell.PutValue("Demo");

　　　　2.4.2 把DataTable寫入到Excel

// 獲取 Table 數據 DataTable dt = GetData();// 寫入數據的起始位置 string cell_start_region = "C1"; // 獲得開始位置的行號 int startRow = DetailSheet.Cells[cell_start_region].Row; // 獲得開始位置的列號 int startColumn = DetailSheet.Cells[cell_start_region].Column; // 寫入Excel。參數說明，直接查閱文章底部文檔鏈接 DetailSheet.Cells.ImportDataTable(dt, false, startRow, startColumn, true, true);

　　2.5 保存Excel

// 設置執行公式計算 - 如果代碼中用到公式，需要設置計算公式，導出的報表中，公式才會自動計算 CurrentWorkbook.CalculateFormula(true);// 生成的文件名稱 string ReportFileName = string.Format("Excel_{0}.xlsx", DateTime.Now.ToString("yyyy-MM-dd"));// 保存文件 CurrentWorkbook.Save(@".\Excel\" + ReportFileName, SaveFormat.Xlsx); ? ? ? /新建工作簿 Workbook workbook = new Workbook(); //工作簿 Worksheet sheet = workbook.Worksheets[0]; //工作表 Cells cells = sheet.Cells;//單元格sheet.Protect(ProtectionType.All, "123123", "");//保護工作表 sheet.Protection.IsSelectingLockedCellsAllowed = false;//設置只能選擇解鎖單元格 sheet.Protection.IsFormattingColumnsAllowed = true;//設置可以調整列 sheet.Protection.IsFormattingRowsAllowed = true;//設置可以調整行Style style1 = workbook.Styles[workbook.Styles.Add()];//新增樣式 style1.HorizontalAlignment = TextAlignmentType.Center;//文字居中 style1.Font.Name = "宋體";//文字字體 style1.Font.Size = 22;//文字大小 style1.IsLocked = false;//單元格解鎖 style1.Font.IsBold = true;//粗體 style1.ForegroundColor = Color.FromArgb(0xaa, 0xcc, 0xbb);//設置背景色 style1.Pattern = BackgroundType.Solid; //設置背景樣式 style1.IsTextWrapped = true;//單元格內容自動換行 style1.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin; //應用邊界線 左邊界線 style1.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin; //應用邊界線 右邊界線 style1.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin; //應用邊界線 上邊界線

style1.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin; //應用邊界線 下邊界線

cells.Merge(0, 0, 1, 5);//合并單元格 cells[0, 0].PutValue("內容");//填寫內容 cells[0, 0].SetStyle(style1);//給單元格關聯樣式cells.SetRowHeight(0, 20);//設置行高 cells.SetColumnWidth(1, 30);//設置列寬 cells[1, 0].Formula = "=AVERAGE(B1:E1)";//給單元格設置計算公式

//從Cells[0,0]開始創建一個2行3列的RangeRange range = ws.Cells.CreateRange(0, 0, 2, 3);Cell cell = range[0, 0];cell.Style.Font = 9;range.Style = style;range.Merge();

注意Range不能直接設置Style.必須先定義style再將style賦給Style.其他設置和Cell基本一致. Range的Style會覆蓋Cell定義的Style.另外必須先賦值再傳Style.否則可能不生效.

sheet.Cells[0,0].PutValue(1);sheet.Cells[1,0].PutValue(20);sheet.Cells[2,0].Formula="SUM(A1:B1)";sheet.CalculateFormula(true);Save Excel文件的時候必須調用CalculateFormula方法計算結果.

?

//********************************************************************************

1.創建execl（不需要服務器或者客戶端安裝office）

public void DCExexl(DataTable dt){Workbook wb = new Workbook();Worksheet ws = wb.Worksheets[0];Cells cell = ws.Cells;

?

?cell[0, 0].PutValue("ID");//添加數據到第0行和第0列

?cell.SetRowHeight(0, 0);設置行高

?Aspose.Cells.Style style1 = wb.Styles[wb.Styles.Add()];style1.HorizontalAlignment = TextAlignmentType.Right;//文字居中

?style1.Font.Name = "宋體";style1.Font.IsBold = true;//設置粗體style1.Font.Size = 12;//設置字體大小

?cell[0, 0].SetStyle(style1);

?cell.SetColumnWidth(0, 10.00);//列寬

Range range = cell.CreateRange(0, 0, 1, 1);//合并單元格 range.Merge();

?string FileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";HttpResponse response = Page.Response;response.Buffer = true;response.Charset = "utf-8";response.AppendHeader("Content-Disposition", "attachment;filename=" + FileName);response.ContentEncoding = System.Text.Encoding.UTF8;response.ContentType = "application/ms-excel";response.BinaryWrite(wb.SaveToStream().ToArray());response.End();

}

2.讀取execl

public DataTable GetDataTable(string path){Workbook workbook = new Workbook();workbook.Open(path);Cells cells = workbook.Worksheets[0].Cells;DataTable dt = new DataTable();bool d = true;//防止表頭重復加載for (int i = 0; i < cells.MaxDataRow + 1; i++){DataRow row = dt.NewRow();for (int j = 0; j < cells.MaxDataColumn + 1; j++){if (d) {dt.Columns.Add(cells[0, j].StringValue.Trim()); }row[j] = cells[i + 1, j].StringValue.Trim();}dt.Rows.Add(row); d = false;}return dt;}

基于Aspose.Cells.dll 封裝了對于導出的Excel的各種樣式設置，內容填充操作，目前支持邊框樣式，顏色，字體，合并單元格等操作,簡化Aspose.Cells.dll的使用

導出例子

GitHub地址

2017/11/15更新后 不再對所謂的標題行標題列作區分(在ExcelFormat對象中只保留SCells屬性，即可配置樣式的單元格集合。除此之外，新增了數據行，數據列，數據區塊的概念，方便一組規則且具有相同樣式的數據區塊插入。為確保配置樣式和插入的靈活性，所有的單元格最終匯總到SCells中等待寫入)

C# 讀寫Excel的一些方法,Aspose.Cells.dll

需求：現有2個Excel，一個7000，一個20W，7000在20W是完全存在的。現要分離20W的，拆分成19W3和7000。

條件：兩個Excel都有“登錄名”，然后用“登錄名”去關聯2個Excel

引用：Aspose.Cells.dll

public void Excel() { //獲取第一個Excel,20Wstring filePath = AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/測試20W.xlsx";System.Data.DataTable table = GetTableFromExcel("sheet1", filePath);//克隆System.Data.DataTable table20W_new = table.Clone();System.Data.DataTable table7000_new = table.Clone(); //獲取第二個Excel,7000string filePath_7000 = AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/測試7000.xls";System.Data.DataTable table_7000 = GetTableFromExcel("sheet1", filePath_7000);//循環20W人中的挑出來for (int i = 0; i < table.Rows.Count; ++i){//20WDataRow dateRow = table.Rows[i];string login_name = dateRow["登錄名"].ToString();//7000DataRow[] drss = table_7000.Select("登錄名 = '" + login_name + "'");if (drss.Length > 0){table7000_new.ImportRow(dateRow);}else{table20W_new.ImportRow(dateRow);}}//導出ExcelDataTableExport(table7000_new, AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/7000.xlsx");DataTableExport(table20W_new, AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/22W.xlsx"); }

獲取Excel內容，轉成DataTable。

/// <summary> /// 獲取Excel內容。 /// </summary> /// <param name="sheetName">工作表名稱，例：sheet1</param> /// <param name="filePath">Excel路徑</param> /// <returns></returns> private DataTable GetTableFromExcel(string sheetName, string filePath) {const string connStrTemplate = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0;HDR=Yes;\"";DataTable dt = null;if (!System.IO.File.Exists(filePath)){// don't find filereturn null;}OleDbConnection conn = new OleDbConnection(string.Format(connStrTemplate, filePath));try{conn.Open();if (sheetName == null || sheetName.Trim().Length == 0){DataTable schemaTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);sheetName = schemaTable.Rows[0]["TABLE_NAME"].ToString().Trim();}else{sheetName += "$";}string strSQL = "Select * From [" + sheetName + "]";OleDbDataAdapter da = new OleDbDataAdapter(strSQL, conn);DataSet ds = new DataSet();da.Fill(ds);dt = ds.Tables[0];}catch (Exception ex){throw ex;}finally{conn.Close();}return dt; }

將DataTable的數據寫進Excel里(用的Aspose.Cells.dll)

/// <summary> /// DataTable數據導出Excel /// </summary> /// <param name="data"></param> /// <param name="filepath"></param> public static void DataTableExport(DataTable data, string filepath) {try{Workbook book = new Workbook();Worksheet sheet = book.Worksheets[0];Cells cells = sheet.Cells;int Colnum = data.Columns.Count;//表格列數 int Rownum = data.Rows.Count;//表格行數 //生成行 列名行 for (int i = 0; i < Colnum; i++){cells[0, i].PutValue(data.Columns[i].ColumnName);}//生成數據行 for (int i = 0; i < Rownum; i++){for (int k = 0; k < Colnum; k++){cells[1 + i, k].PutValue(data.Rows[i][k].ToString());}}book.Save(filepath);GC.Collect();}catch (Exception e){logger.Error("生成excel出錯：" + e.Message);} }

將List的數據寫進Excel里(用的Aspose.Cells.dll)

/// <summary> /// 導出excel /// </summary> /// <typeparam name="T"></typeparam> /// <param name="data">Ilist集合</param> /// <param name="filepath">保存的地址</param> public static void Export<T>(IList<T> data, string filepath) {try{Workbook workbook = new Workbook();Worksheet sheet = (Worksheet)workbook.Worksheets[0];PropertyInfo[] ps = typeof(T).GetProperties();var colIndex = "A";foreach (var p in ps){// sheet.Cells[colIndex + 1].PutValue(p.Name);//設置表頭名稱 要求表頭為中文所以不用 p.name 為字段名稱 可在list第一條數據為表頭名稱int i = 1;foreach (var d in data){sheet.Cells[colIndex + i].PutValue(p.GetValue(d, null));i++;}colIndex = getxls_top(colIndex); //((char)(colIndex[0] + 1)).ToString();//表頭 A1/A2/ }//workbook.Shared = true; workbook.Save(filepath);GC.Collect();}catch (Exception e){logger.Error("生成excel出錯：" + e.Message);} } /// <summary> /// 生成新的對應的列 A-Z AA-ZZ /// </summary> /// <param name="top">當前列</param> /// <returns></returns> private static string getxls_top(string top) {char[] toplist = top.ToArray();var itemtop = top.Last();string topstr = string.Empty;if ((char)itemtop == 90)//最后一個是Z {if (toplist.Count() == 1){topstr = "AA";}else{toplist[0] = (char)(toplist[0] + 1);toplist[toplist.Count() - 1] = 'A';foreach (var item in toplist){topstr += item.ToString();}}}else//最后一個不是Z 包括top為兩個字符 {itemtop = (char)(itemtop + 1);toplist[toplist.Count() - 1] = itemtop;foreach (var item in toplist){topstr += item.ToString();}}return topstr; }

將DataTable的數據寫進Excel里(用的Microsoft.Office.Interop.Excel.dll)(此方法在大量數據的時候很慢，例如22W條數據，建議使用Aspose.Cells.dll，速度快很多)

/// <summary> /// 將DataTable的數據寫進Excel里 /// </summary> /// <param name="tmpDataTable">DataTable數據</param> /// <param name="strFileName">Excel路徑</param> public static void DataTabletoExcel(System.Data.DataTable tmpDataTable, string strFileName) {if (tmpDataTable == null){return;}int rowNum = tmpDataTable.Rows.Count;int columnNum = tmpDataTable.Columns.Count;int rowIndex = 1;int columnIndex = 0;//需要引用Microsoft.Office.Interop.Excel.dllMicrosoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.ApplicationClass();xlApp.DefaultFilePath = "";xlApp.DisplayAlerts = true;xlApp.SheetsInNewWorkbook = 1;Microsoft.Office.Interop.Excel.Workbook xlBook = xlApp.Workbooks.Add(true);//將DataTable的列名導入Excel表第一行foreach (DataColumn dc in tmpDataTable.Columns){columnIndex++;xlApp.Cells[rowIndex, columnIndex] = dc.ColumnName;}//將DataTable中的數據導入Excel中for (int i = 0; i < rowNum; i++){rowIndex++;columnIndex = 0;for (int j = 0; j < columnNum; j++){columnIndex++;xlApp.Cells[rowIndex, columnIndex] = tmpDataTable.Rows[i][j].ToString();}}//xlBook.SaveCopyAs(HttpUtility.UrlDecode(strFileName, System.Text.Encoding.UTF8)); xlBook.SaveCopyAs(strFileName); }

原生的DataTable生成Excel(無需引用第三方dll)

/// <summary> /// 將DataTable的數據寫進Excel里 /// </summary> /// <param name="tdKeChengZhuanJiaTongJi">DataTable</param> /// <param name="sheet">sheet自定義名稱</param> /// <param name="fileName">Excel路徑</param> public static void DataTabletoExcel(DataTable dt, string sheet, string fileName) {String sConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0 Xml;\"";//string sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";Extended Properties='Excel 8.0;HDR=Yes;'";//String sConnectionString = "Provider=Microsoft.ACE.OLEDB.14.0;Data Source=" + fileName + ";Extended Properties=\"Excel 14.0 Xml;\"";//String sConnectionString = "Provider=Microsoft.ACE.OLEDB.16.0;Data Source=" + fileName + ";Extended Properties=\"Excel 16.0 Xml;HDR=YES;\""; OleDbConnection cn = new OleDbConnection(sConnectionString); int rowNum = dt.Rows.Count;//獲取行數int colNum = dt.Columns.Count;//獲取列數string sqlText = "";//帶類型的列名string sqlValues = "";//值string colCaption = "";//列名for (int i = 0; i < colNum; i++){if (i != 0){sqlText += " , ";colCaption += " , ";}sqlText += "[" + dt.Columns[i].Caption.ToString() + "] VarChar";//生成帶VarChar列的標題colCaption += "[" + dt.Columns[i].Caption.ToString() + "]";//生成列的標題 }try{//打開連接 cn.Open();string sqlCreate = "CREATE TABLE [" + sheet.ToString() + "] (" + sqlText + ")";OleDbCommand cmd = new OleDbCommand(sqlCreate, cn);//創建Excel文件 cmd.ExecuteNonQuery();for (int srow = 0; srow < rowNum; srow++){sqlValues = "";for (int col = 0; col < colNum; col++){if (col != 0){sqlValues += " , ";}sqlValues += "'" + dt.Rows[srow][col].ToString() + "'";//拼接Value語句 }String queryString = "INSERT INTO [" + sheet.ToString() + "] (" + colCaption + ") VALUES (" + sqlValues + ")";cmd.CommandText = queryString;cmd.ExecuteNonQuery();//插入數據 }}catch{//生成日志}finally{cn.Close();} }

1.添加引用：Aspose.Cells.dll（我們就叫工具包吧，可以從網上下載。關于它的操作我在“Aspose.Cells操作說明 中文版 下載 Aspose C# 導出Excel 實例”一文中的說。這里你暫時也可不理會它。） 即使沒有安裝office也能用噢，這是一個好強的大工具。 2.編寫Excel操作類using System; using System.Collections.Generic; using System.Text; using Aspose.Cells; using System.Data; public class AsposeExcel {private string outFileName = "";private string fullFilename = "";private Workbook book = null;private Worksheet sheet = null;public AsposeExcel(string outfilename, string tempfilename) //導出構造數{outFileName = outfilename;book = new Workbook();// book.Open(tempfilename);這里我們暫時不用模板sheet = book.Worksheets[0];}public AsposeExcel(string fullfilename) //導入構造數{fullFilename = fullfilename;// book = new Workbook();// book.Open(tempfilename);// sheet = book.Worksheets[0];}private void AddTitle(string title, int columnCount){sheet.Cells.Merge(0, 0, 1, columnCount);sheet.Cells.Merge(1, 0, 1, columnCount);Cell cell1 = sheet.Cells[0, 0];cell1.PutValue(title);cell1.Style.HorizontalAlignment = TextAlignmentType.Center;cell1.Style.Font.Name = "黑體";cell1.Style.Font.Size = 14;cell1.Style.Font.IsBold = true;Cell cell2 = sheet.Cells[1, 0];cell1.PutValue("查詢時間：" + DateTime.Now.ToLocalTime());cell2.SetStyle(cell1.Style);}private void AddHeader(DataTable dt){Cell cell = null;for (int col = 0; col < dt.Columns.Count; col++){cell = sheet.Cells[0, col];cell.PutValue(dt.Columns[col].ColumnName);cell.Style.Font.IsBold = true;}}private void AddBody(DataTable dt){for (int r = 0; r < dt.Rows.Count; r++){for (int c = 0; c < dt.Columns.Count; c++){sheet.Cells[r + 1, c].PutValue(dt.Rows[R]-[c].ToString());}}}//導出------------下一篇會用到這個方法public Boolean DatatableToExcel(DataTable dt){Boolean yn = false;try{//sheet.Name = sheetName;//AddTitle(title, dt.Columns.Count);//AddHeader(dt);AddBody(dt);sheet.AutoFitColumns();//sheet.AutoFitRows();book.Save(outFileName);yn = true;return yn;}catch (Exception e){return yn;// throw e;}}public DataTable ExcelToDatatalbe()//導入{Workbook book = new Workbook();book.Open(fullFilename);Worksheet sheet = book.Worksheets[0];Cells cells = sheet.Cells;//獲取excel中的數據保存到一個datatable中DataTable dt_Import = cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, false);// dt_Import.return dt_Import;} }[/R]3.

Aspose.Cells小實例

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();Aspose.Cells.Worksheet sheet = workbook.Worksheets[0];sheet.FreezePanes(1, 1, 1, 0);//凍結第一行sheet.Cells["A1"].PutValue("ID");sheet.Cells["B1"].PutValue("手機號碼");sheet.Cells["C1"].PutValue("姓名");sheet.Cells["D1"].PutValue("出生年月");sheet.Cells["E1"].PutValue("性別");sheet.Cells["F1"].PutValue("訂購份數");sheet.Cells["G1"].PutValue("運營產品ID");sheet.Cells["H1"].PutValue("訂單狀態");sheet.Cells["I1"].PutValue("訂單成功時間");sheet.Cells["J1"].PutValue("批次ID");sheet.Cells["K1"].PutValue("支付方式");sheet.Cells["L1"].PutValue("錯誤代碼");///TODO///設置列1為文本，因為這列全是數字而且很長，不處理會變成自然數了。///這里需要注意Style是設置風格，而StyleFlag是開關，所以即使你設置了Style，沒有打開對應的StyleFlag一樣沒用Aspose.Cells.Style sc1 = workbook.Styles[workbook.Styles.Add()];sc1.ShrinkToFit = true;sc1.Number = 49;Aspose.Cells.StyleFlag scf1 = new Aspose.Cells.StyleFlag();scf1.ShrinkToFit = true;scf1.NumberFormat = true;Aspose.Cells.Column colomn1 = sheet.Cells.Columns[1];colomn1.ApplyStyle(sc1, scf1);dt =getDataTable();//得到DataTablesheet.Cells.ImportDataTable(dt, false, "A2");//從A2開始填充數據sheet.AutoFitColumns();//讓各列自適應寬度，這個很有用。workbook.Save(fileName, Aspose.Cells.FileFormatType.Excel2007Xlsx, Aspose.Cells.SaveType.OpenInExcel, response);//輸出

很多時候輸出的數據排序或者顯示的列并不一定和DataTable得到的列排序數據完全一致，那么我們可以簡單處理一下：比如把上面的

引用內容///TODO///設置列1為文本，因為這列全是數字而且很長，不處理會變成自然數了。///這里需要注意Style是設置風格，而StyleFlag是開關，所以即使你設置了Style，沒有打開對應的StyleFlag一樣沒用Aspose.Cells.Style sc1 = workbook.Styles[workbook.Styles.Add()];sc1.ShrinkToFit = true;sc1.Number = 49;Aspose.Cells.StyleFlag scf1 = new Aspose.Cells.StyleFlag();scf1.ShrinkToFit = true;scf1.NumberFormat = true;Aspose.Cells.Column colomn1 = sheet.Cells.Columns[1];colomn1.ApplyStyle(sc1, scf1);dt =getDataTable();//得到DataTable

替換成：

引用內容DataTable dt1=getDataTable();for (int i = 0; i < dt1.Rows.Count; i++){sheet.Cells[(i + 1), 0].PutValue(dt1.Rows[i]["create_time"].ToString());sheet.Cells[(i + 1), 1].PutValue(dt1.Rows[i]["holder_mobile"].ToString());sheet.Cells[(i + 1), 2].PutValue(dt1.Rows[i]["rec_name"].ToString());sheet.Cells[(i + 1), 3].PutValue(string.IsNullOrEmpty(dt1.Rows[i]["rec_sex"].ToString()) ? "" : (dt1.Rows[i]["rec_sex"].ToString() == "1") ? "男" : "女");sheet.Cells[(i + 1), 4].PutValue(dt1.Rows[i]["rec_birthday"].ToString());sheet.Cells[(i + 1), 5].PutValue(dt1.Rows[i]["base_product_code"].ToString());sheet.Cells[(i + 1), 6].PutValue(dt1.Rows[i]["sell_price"].ToString());sheet.Cells[(i + 1), 7].PutValue(dt1.Rows[i]["pay_count"].ToString());sheet.Cells[(i + 1), 8].PutValue(dt1.Rows[i]["ins_policy"].ToString());sheet.Cells[(i + 1), 9].PutValue(dt1.Rows[i]["ins_end_date"].ToString());sheet.Cells[(i + 1), 10].PutValue(Rondi.Insu.Management.Utility.StateEnum.OrderFrom(dt1.Rows[i]["order_from"].ToString()));sheet.Cells[(i + 1), 11].PutValue(Rondi.Insu.Management.Utility.StateEnum.OrderState(dt1.Rows[i]["order_state"].ToString()));}
