Crystal Report在发布数据库时请求数据库登录

Question

我正在WPF中开发一个应用程序，它需要从中获取报告，我完成并在我的电脑中一切正常，没有数据库登录对话框出现，并且完全没问题。但是，当我想通过Crystal Report Viewer显示报表时，在客户端PC上发布数据库登录对话框时！我做了所有想到的事情，并在网络上到处搜索，尽我所能，但无法解决这个问题。 这是我的代码：

ReportDocument CryRpt1 = new ReportDocument(); 
string Path1 = System.Windows.Forms.Application.StartupPath + "\\CryReportSendItems.rpt"; 
CryRpt1.Load(Path1, OpenReportMethod.OpenReportByDefault); 
AssignConnection(CryRpt1); 
CryRpt1.Refresh(); 
Crv.ViewerCore.ReportSource = CryRpt1; 

这是AssignConnection方法：

private void AssignConnection(ReportDocument rpt) 
     { 
      ConnectionInfo connection = new ConnectionInfo();   
      connection.ServerName = "*ServerName*"; 
      connection.DatabaseName = "*DBName*"; 
      connection.UserID = "*User*"; 
      connection.Password = "*Password*"; 

      foreach (CrystalDecisions.CrystalReports.Engine.Table table in rpt.Database.Tables) 
      { 
       AssignTableConnection(table, connection); 
      } 

      foreach (CrystalDecisions.CrystalReports.Engine.Section section in rpt.ReportDefinition.Sections) 
      { 

       foreach (CrystalDecisions.CrystalReports.Engine.ReportObject reportObject in section.ReportObjects) 
       { 
        if (reportObject.Kind == ReportObjectKind.SubreportObject) 
        { 
         SubreportObject subReport = (SubreportObject)reportObject; 
         ReportDocument subDocument = subReport.OpenSubreport(subReport.SubreportName); 

         foreach (CrystalDecisions.CrystalReports.Engine.Table table in subDocument.Database.Tables) 
         { 
          AssignTableConnection(table, connection); 
         } 

         subDocument.SetDatabaseLogon(connection.UserID, connection.Password, connection.ServerName, connection.DatabaseName); 
        } 
       } 
      } 
      rpt.SetDatabaseLogon(connection.UserID, connection.Password, connection.ServerName, connection.DatabaseName); 
     } 

     private void AssignTableConnection(CrystalDecisions.CrystalReports.Engine.Table table, ConnectionInfo connection) 
     { 
      // Cache the logon info block 
      TableLogOnInfo logOnInfo = table.LogOnInfo; 

      connection.Type = logOnInfo.ConnectionInfo.Type; 

      // Set the connection 
      logOnInfo.ConnectionInfo = connection; 

      // Apply the connection to the table! 

      table.LogOnInfo.ConnectionInfo.DatabaseName = connection.DatabaseName; 
      table.LogOnInfo.ConnectionInfo.ServerName = connection.ServerName; 
      table.LogOnInfo.ConnectionInfo.UserID = connection.UserID; 
      table.LogOnInfo.ConnectionInfo.Password = connection.Password; 
      table.LogOnInfo.ConnectionInfo.Type = connection.Type; 
      table.ApplyLogOnInfo(logOnInfo); 
     } 

*注：我的Windows版本是10（64）和客户端的Windows版本是7（64位）。

有些人可以帮我吗？

我找到了答案，可能会有人利用这个：

使用实体框架的代码填入再次报告。

 using (var db = new DatabaseContext()) 
     { 
      CryRpt1.SetDataSource(db.VwSendItems); 
     } 

，并在此之前：

 SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder("Data Source=*Server*;Initial Catalog=*DBCenter*;Persist Security Info=True;User ID=*User*;password=*Password*"); //from config.xml 
     crConnectionInfo.ServerName = builder.DataSource; 
     crConnectionInfo.DatabaseName = builder.InitialCatalog; 
     crConnectionInfo.IntegratedSecurity = true; 

     CrTables = CryRpt1.Database.Tables; 
     foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables) 
     { 
      crtableLogoninfo = CrTable.LogOnInfo; 
      crtableLogoninfo.ConnectionInfo = crConnectionInfo; 
      CrTable.ApplyLogOnInfo(crtableLogoninfo); 
     } 

     //AssignConnection(CryRpt1); 
     ConnectionInfo connection = new ConnectionInfo 
     { 
      ServerName = "10.20.1.41", 
      DatabaseName = "DBCenterMostafavi", 
      UserID = "site", 
      Password = "123!@#a" 
     }; 
     CryRpt1.SetDatabaseLogon(connection.UserID, connection.Password, connection.ServerName, connection.DatabaseName); 

     foreach (CrystalDecisions.CrystalReports.Engine.Table table in CryRpt1.Database.Tables) 
     { 
      AssignTableConnection(table, connection); 
     } 

就是这样。
