2013-11-13 10:51:27  來源: .NET編程 

  雙擊button添加button_Click點擊事件

  private void button_Click(object sender SystemEventArgs e)
  {
   try
   {
    if(openFileDialogShowDialog()==DialogResultOK)
    thiscrystalReportViewerReportSource = @openFileDialogFileName;
    //加載水晶報表將報表文件綁定到CrystalReportView 控件;
   }
   catch(Exception error)
   {
    MessageBoxShow(errorToString()錯誤);
   }
  }

  OK!按Ctrl+F運行吧

  可以浏覽你系統內現有的報表實例
