asp.net|打印|水晶报表　　在ASP.NET中水晶报表没有象在Windows Form中那样提供报表的导出和打印功能，需要我们自己动手添加代码来控制，下面给个DEMO：

　　导出：
myReport  ReportDoc = new myReport();//表表的名称
private void btnExport_Click(object sender, System.EventArgs e)
  {
   CrystalDecisions.Shared.DiskFileDestinationOptions DiskOpts = new  CrystalDecisions.Shared.DiskFileDestinationOptions();
   ReportDoc.ExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;
   switch (DropDownList1.SelectedItem.Text)
   {
    case "Rich Text (RTF)":
　      ReportDoc.ExportOptions.ExportFormatType =   CrystalDecisions.Shared.ExportFormatType.RichText;
　      DiskOpts.DiskFileName = "d:\\demo.rtf";
     break;
    case "Portable Document (PDF)":
　      ReportDoc.ExportOptions.ExportFormatType =   CrystalDecisions.Shared.ExportFormatType.PortableDocFormat;
　      DiskOpts.DiskFileName = "d:\\demo.pdf";
     break;
    case "MS Word (DOC)":
　      ReportDoc.ExportOptions.ExportFormatType =   CrystalDecisions.Shared.ExportFormatType.WordForWindows;
　      DiskOpts.DiskFileName = "d:\\demo.doc";
     break;
    case "MS Excel (XLS)":
　      ReportDoc.ExportOptions.ExportFormatType =   CrystalDecisions.Shared.ExportFormatType.Excel;
　      DiskOpts.DiskFileName = "d:\\demo.xls";
     break;
    default:
     break;
   }
   ReportDoc.ExportOptions.DestinationOptions = DiskOpts;
　   ReportDoc.Export();
  }

　　打印：
private void btnPrint_Click(object sender, System.EventArgs e)
  {
     string strPrinterName; // 指定打印机名称     
   strPrinterName = "Canon Bubble-Jet BJC-210SP"; 
   PageMargins margins;  // 设置打印页边距
   margins = ReportDoc.PrintOptions.PageMargins;
   margins.bottomMargin = 250;
   margins.leftMargin = 350;
   margins.rightMargin = 350;
   margins.topMargin = 450;    
   ReportDoc.PrintOptions.ApplyPageMargins(margins);     
   ReportDoc.PrintOptions.PrinterName = strPrinterName;  //应用打印机名称    
     // 打印报表.startPageN 和 endPageN
   // 参数设置为 0 表示打印所有页。
   ReportDoc.PrintToPrinter(1, false,0,0);     
   }
