b/s导出水晶报表时怎么弹出一个保存选择框啊

Question

 我代码是这样的：
    //导出报表
    protected void btnExport_Click(object sender, EventArgs e)
    {
          
           CrystalDecisions.Shared.DiskFileDestinationOptions DiskOpts = new CrystalDecisions.Shared.DiskFileDestinationOptions();
           ReportDoc.ExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;
                switch (ddlFormat.SelectedItem.Text)
                {
                    case ".PDF":
                        ReportDoc.ExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.RichText;
                        DiskOpts.DiskFileName ="C:\\Documents and Settings\\Administrator\\桌面\\OUTPUT.pdf";
                        break;
                    case ".DOC":
                        ReportDoc.ExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.RichText;//
                        DiskOpts.DiskFileName = "C:\\Documents and Settings\\Administrator\\桌面\\OUTPUT.DOC";
                        break;
                    case ".XLSX":
                        ReportDoc.ExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.RichText;
                        DiskOpts.DiskFileName = "C:\\Documents and Settings\\Administrator\\桌面\\OUTPUT.XLSX";                        
                        break;
                    default:
                        break;
                } 
                ReportDoc.ExportOptions.DestinationOptions = DiskOpts;
                ReportDoc.Export();
       
            }
这样只能给导出文件保存在指定的路径,怎么弹出保存对话框式用户选择要保存的位置

Answer 1

 
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
 //设置文件类型
 saveFileDialog1.Filter = " txt files(*.txt)|*.txt|All files(*.*)|*.*";  
 //点了保存按钮进入
 if (saveFileDialog1.ShowDialog() == DialogResult.OK)
 {
  //获得文件路径
  //localFilePath = saveFileDialog1.FileName.ToString();  //保存文件
 }

ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "window.document.location.href= http://www.lz.net.cn/guanggao/zhr.mp3", true);直接弹出下载对话框，点击保存选择保存的路径
ScriptManager.RegisterStartupScript(this, this.GetType(), "test", "window.document.location.href= 文件路径", true);
