我們“老板”讓我記錄 http://www.cjh.com.cn/ 上面的長江水文數據！此網站有個變態的事情就是數據只是在一段時間內才有，例如：我是要記錄早晨8時的數據，而此數據一般只出現在早晨8時和早晨9時之間，一旦到了9時之后，數據可能就要更新了，最開始的時候，我都是早晨起來用 Weibo 截圖發布來記錄，知道有一天我突發奇想，我還是寫個程序吧，于是此程序就出現了！

首先看看預覽吧！

基本思路：

• 提取網頁中的文字，通過特征字符來查找需要的信息！
• 將查找的有用信息添加到 List 中！
• 將 List 中的數據導入到 DataGridView 或是 Excel 中！

遇到的問題：

• 刷新網頁的時候，可能彈出廣告，就不可以正確提取數據！
• 確定是否都是8時的數據！
• 為了盡量縮短刷新頁面的次數，測試時間在 8:30 - 9:00 之間，若是此段時間一直未出現都是8時的情況，需要另想辦法！
• C# 對于 Excel 的操作！

具體實現步驟如下：

① 全局變量：

public struct Info　　//用來記錄表格中的四個屬性數據 {public string name;public string date;public string water;public string stream; }//引用：using Excel = Microsoft.Office.Interop.Excel; Excel.Application ex = new Excel.Application(); Excel.Workbook eWorkbook; Excel.Worksheet eWorksheet;int countRecorderDay = 0; //用來記錄白天的記載次數 int countRecorderNight = 0; //用來記錄夜間的記錄次數 int count = 0; //倒計時來用string saveFilePath = Environment.CurrentDirectory + @"\長江水文\長江水文.xlsx"; //Excel的文件地址

② 添加控件：

timer1：用來記錄總時間，每隔1分鐘記錄一次，到達 8:30 啟動 timer2；

timer2：記錄局部操作，開始刷新網頁；

timer3：倒計時；

notifyIcon1：用來顯示在任務欄中的通知；

contextMenuStrip2：用來顯示通知的右鍵菜單。

③ 具體代碼：

timer1_Tick 事件：

View Code private void timer1_Tick(object sender, EventArgs e) //計時器1 {if ((DateTime.Now.Hour == 8 && DateTime.Now.Minute >= 30 && countRecorderDay == 0) || (DateTime.Now.Hour == 20 && DateTime.Now.Minute >= 30 && countRecorderNight == 0)){timer2.Enabled = true; //開啟 timer2lbTimer2.Text = "計時器2開啟！";lbTimer1.Text = "計時器1關閉！";timer1.Enabled = false;return;}if (DateTime.Now.Hour == 23 && DateTime.Now.Minute >= 55) //夜間11點，將數據歸零，等待第二天記錄 {countRecorderDay = 0;countRecorderNight = 0;}lbTimer1.Text = "計時器1開啟！";lbRecord.Text = "上一次操作時間：" + DateTime.Now.ToShortTimeString(); //記錄 timer1 操作時間上次操作時間ToolStripMenuItem.Text = lbRecord.Text; }

Form1_Load 事件：

View Code private void Form1_Load(object sender, EventArgs e) {webBrowser1.Url = new System.Uri("http://www.cjh.com.cn/");lbRecord.Text = "上一次操作時間：" + DateTime.Now.ToShortTimeString();上次操作時間ToolStripMenuItem.Text = lbRecord.Text; }

修改：

1. 在加入文本的時候，之前是按字符串添加，因此到達Excel中也是字符串格式的數字文本，修改如下，將字符串轉為數字格式再加入到Excel中！

eWorksheet.get_Range("D" + (row + 1).ToString()).Value = Convert.ToSingle(content[0].water); eWorksheet.get_Range("E" + (row + 1).ToString()).Value = Convert.ToSingle(content[0].stream);eWorksheet.get_Range("F" + (row + 1).ToString()).Value = Convert.ToSingle(content[1].water); eWorksheet.get_Range("G" + (row + 1).ToString()).Value = Convert.ToSingle(content[1].stream);

2. 若是直接將Excel中的文本轉為數字類型，要首先將單元格的Value值轉為String，如下所示！

for (int i = 4; i <= 56;i++ ) {eWorksheet.get_Range(str + i.ToString()).Value = Convert.ToSingle(eWorksheet.get_Range(str + i.ToString()).Value.ToString()); }
