昨天嘗試了一下，不使用Web Service，本地使用同樣的方法
????????string?strCon;

????????DataSet?ds?=?new?DataSet();
????????XmlDataDocument?xmlDataDoc;

????????strCon?=?"Server=10.100.3.248;initial?catalog=IGS-SMP-WorkTest;User?Id=WorkDeveloper;Password=developer;";

????????string?selectText?=?"SELECT?*?FROM?SMP_WorkItem";

????????SqlDataAdapter?dataAdapter?=?new?SqlDataAdapter(selectText,?strCon);


????????try
????????{
????????????dataAdapter.Fill(ds);

????????????xmlDataDoc?=?new?XmlDataDocument(ds);

????????????using(XmlTextWriter?writer?=?new?XmlTextWriter("Your?Report?Location",System.Text.Encoding.UTF8))
????????????{

?????????
????????????xmlDataDoc.WriteTo(writer);
???????
????????????writer.Flush();
????????????}

????????}
????????catch
????????{
????????????xmlDataDoc?=?null;
????????}
????????finally
????????{
????????????strCon?=?null;
????????????ds.Dispose();
????????}
????}

然后在Shared Data Source里指定生成的文件路徑，Query String根據微軟的說明，為空就可以了。
但是不能正確識別XML文件格式，參照向導生成的格式，缺少了很多元素。

通過查找資料的時候發現一個解決方案，我們可以自己制作一個報表生成器，步驟如下：

1. 新建一個Console Application,建立報表生成器：
using?System;
using?System.Collections;
using?System.Data;
using?System.Data.SqlClient;
using?System.IO;
using?System.Text;
using?System.Xml;

namespace?RDLGenerator
{
????class?RdlGenerator
????{
????????SqlConnection?m_connection;
????????string?m_connectString;
????????string?m_commandText;
????????ArrayList?m_fields;

????????public?static?void?Main()
????????{
????????????RdlGenerator?myRdlGenerator?=?new?RdlGenerator();
????????????myRdlGenerator.Run();
????????}

????????public?void?Run()
????????{
????????????try
????????????{
????????????????//?Call?methods?to?create?the?RDL
????????????????this.OpenConnection();
????????????????this.GenerateFieldsList();
????????????????this.GenerateRdl();

????????????????Console.WriteLine("RDL?file?generated?successfully.");
????????????}

????????????catch?(Exception?exception)
????????????{
????????????????Console.WriteLine("An?error?occurred:?"?+?exception.Message);
????????????}

????????????finally
????????????{
????????????????//?Close?the?connection?string
????????????????m_connection.Close();
????????????}
????????}

????????public?void?OpenConnection()
????????{
????????????TODO:OpenConnection
????????}


????????public?void?GenerateFieldsList()
????????{
????????????TODO:GenerateFieldsList
????????}


????????public?void?GenerateRdl()
????????{
???????????TODO:?GenerateRdl
????????}


????}
}
2.創建你自己的數據庫連接：
????????public?void?OpenConnection()
????????{
????????????//?Create?a?connection?object
????????????m_connection?=?new?SqlConnection();

????????????//?Create?the?connection?string
????????????m_connectString?=?"Your?Connnection?String
????????????m_connection.ConnectionString?=?m_connectString;

????????????//?Open?the?connection
????????????m_connection.Open();
????????} 3.獲取你需要的數據：

????????public?void?GenerateFieldsList()
????????{
????????????SqlCommand?command;
????????????SqlDataReader?reader;

????????????//?Executing?a?query?to?retrieve?a?fields?list?for?the?report
????????????command?=?m_connection.CreateCommand();
????????????m_commandText?=
???????????????"Your?SELECT?STRING";
????????????command.CommandText?=?m_commandText;

????????????//?Execute?and?create?a?reader?for?the?current?command
????????????reader?=?command.ExecuteReader(CommandBehavior.SchemaOnly);

????????????//?For?each?field?in?the?resultset,?add?the?name?to?an?array?list
????????????m_fields?=?new?ArrayList();
????????????for?(int?i?=?0;?i?<=?reader.FieldCount?-?1;?i++)
????????????{
????????????????m_fields.Add(reader.GetName(i));
????????????}
????????}

4.創建報表XML：
????????public?void?GenerateRdl()
????????{
????????????//?Open?a?new?RDL?file?stream?for?writing
????????????FileStream?stream;
????????????stream?=?File.OpenWrite("Report1.rdl");
????????????XmlTextWriter?writer?=?new?XmlTextWriter(stream,?Encoding.UTF8);

????????????//?Causes?child?elements?to?be?indented
????????????writer.Formatting?=?Formatting.Indented;

????????????//?Report?element
????????????writer.WriteProcessingInstruction("xml",?"version=\"1.0\"?encoding=\"utf-8\"");
????????????writer.WriteStartElement("Report");
????????????writer.WriteAttributeString("xmlns",?null,?"http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition");
????????????writer.WriteAttributeString("xmlns:rd",?null,?"http://schemas.microsoft.com/SQLServer/reporting/reportdesigner");
????????????writer.WriteElementString("Width",?"6in");

????????????//?DataSource?element
????????????writer.WriteStartElement("DataSources");
????????????writer.WriteStartElement("DataSource");
????????????writer.WriteAttributeString("Name",?null,?"DataSource1");
????????????writer.WriteStartElement("ConnectionProperties");
????????????writer.WriteElementString("DataProvider",?"SQL");
????????????writer.WriteElementString("ConnectString",?m_connectString);
????????????writer.WriteElementString("IntegratedSecurity",?"false");
????????????writer.WriteEndElement();?//?ConnectionProperties
????????????writer.WriteEndElement();?//?DataSource
????????????writer.WriteEndElement();?//?DataSources

????????????//?DataSet?element
????????????writer.WriteStartElement("DataSets");
????????????writer.WriteStartElement("DataSet");
????????????writer.WriteAttributeString("Name",?null,?"DataSet1");

????????????//?Query?element
????????????writer.WriteStartElement("Query");
????????????writer.WriteElementString("DataSourceName",?"DataSource1");
????????????writer.WriteElementString("CommandType",?"Text");
????????????writer.WriteElementString("CommandText",?m_commandText);
????????????writer.WriteElementString("Timeout",?"30");
????????????writer.WriteEndElement();?//?Query

????????????//?Fields?elements
????????????writer.WriteStartElement("Fields");
????????????foreach?(string?fieldName?in?m_fields)
????????????{
????????????????writer.WriteStartElement("Field");
????????????????writer.WriteAttributeString("Name",?null,?fieldName);
????????????????writer.WriteElementString("DataField",?null,?fieldName);
????????????????writer.WriteEndElement();?//?Field
????????????}

????????????//?End?previous?elements
????????????writer.WriteEndElement();?//?Fields
????????????writer.WriteEndElement();?//?DataSet
????????????writer.WriteEndElement();?//?DataSets

????????????//?Body?element
????????????writer.WriteStartElement("Body");
????????????writer.WriteElementString("Height",?"5in");

????????????//?ReportItems?element
????????????writer.WriteStartElement("ReportItems");

????????????//?Table?element
????????????writer.WriteStartElement("Table");
????????????writer.WriteAttributeString("Name",?null,?"Table1");
????????????writer.WriteElementString("DataSetName",?"DataSet1");
????????????writer.WriteElementString("Top",?".5in");
????????????writer.WriteElementString("Left",?".5in");
????????????writer.WriteElementString("Height",?".5in");
????????????writer.WriteElementString("Width",?(m_fields.Count?*?1.5)?+?"in");

????????????//?Table?Columns
????????????writer.WriteStartElement("TableColumns");
????????????for?(int?i?=?0;?i?<?m_fields.Count;?i++)
????????????{
????????????????writer.WriteStartElement("TableColumn");
????????????????writer.WriteElementString("Width",?"1.5in");
????????????????writer.WriteEndElement();?//?TableColumn
????????????}
????????????writer.WriteEndElement();?//?TableColumns

????????????//?Header?Row
????????????writer.WriteStartElement("Header");
????????????writer.WriteStartElement("TableRows");
????????????writer.WriteStartElement("TableRow");
????????????writer.WriteElementString("Height",?".25in");
????????????writer.WriteStartElement("TableCells");

????????????foreach?(string?fieldName?in?m_fields)
????????????{
????????????????writer.WriteStartElement("TableCell");
????????????????writer.WriteStartElement("ReportItems");

????????????????//?Textbox
????????????????writer.WriteStartElement("Textbox");
????????????????writer.WriteAttributeString("Name",?null,?"Header"?+?fieldName);

????????????????writer.WriteStartElement("Style");
????????????????writer.WriteElementString("TextDecoration",?"Underline");
????????????????writer.WriteEndElement();?//?Style

????????????????writer.WriteElementString("Top",?"0in");
????????????????writer.WriteElementString("Left",?"0in");
????????????????writer.WriteElementString("Height",?".5in");
????????????????writer.WriteElementString("Width",?"1.5in");
????????????????writer.WriteElementString("Value",?fieldName);
????????????????writer.WriteEndElement();?//?Textbox

????????????}

????????????writer.WriteEndElement();?//?TableCells
????????????writer.WriteEndElement();?//?TableRow

????????????//?Flush?the?writer?and?close?the?stream
????????????writer.Flush();
????????????stream.Close();
????????}

5.編譯運行你的程序，選擇Start Without Debugging.

然后一個rdl格式的報表文件就生成在你制定的目錄了，你只要在Report Services Project中添加這個報表進一步設計就可以了。

不過我們可以主要到GenerateRdl方法中的XML基本都是手動方式添加元素，如果把前面的SqlDataReader換成DataSet，那么GenerateRdl方法中的語句也要重寫，所以不是特別方便。

這里只是提供一種選擇，是好事壞，是否選擇，那就是使用者自己的事情了。
