您好Shailendra，

Crystal Report提供了内置的方法，可以将其转换为不同的格式

绑定水晶报表后，下面是将其导出为pdf格式的代码.
ExportOptions exportOpts = doc.ExportOptions;
exportOpts.ExportFormatType = ExportFormatType.PortableDocFormat;
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
exportOpts.DestinationOptions =新的DiskFileDestinationOptions();

Hi Shailendra,

There is built in methods available from crystal report to convert it into different formats

After binding your crystal report below is the code for exporting it into pdf format.
ExportOptions exportOpts = doc.ExportOptions;
exportOpts.ExportFormatType = ExportFormatType.PortableDocFormat;
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
exportOpts.DestinationOptions = new DiskFileDestinationOptions();

DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
            ( ( DiskFileDestinationOptions )doc.ExportOptions.DestinationOptions ).DiskFileName = Server.MapPath("fin.pdf");
            doc.Export();
            Response.Write(dt.Rows.Count);
            Response.Write("<a href=\"" + pdfFile + "\">" + pdfFile + "</a>"

);


如果要选择导出格式，则在Crystal Report Viewer中内置选项.

希望这有助于

If you want to provide selection of export format there is built in option in crystal report viewer.

Hope this helps

Crystal报表本身支持此功能.据我所知，您只需要导出水晶报表，它就会询问格式和路径

Crystal reports itself support this . As far as i know you just need to export crystal report and it will ask for the format and path

您好Shailendra，

要将Crystal Report转换为PDF，请执行以下步骤:

将Crystal Report View添加到您的页面

并尝试我的代码进行转换

DataTable dt = new DataTable();

//在Datatable下面调用您的类和方法，
dt = Designation.fillgrid();
尝试
{
如果(dt.Rows.Count& gt; 0)
{
ReportDocument rptdoc = new ReportDocument();
//在这里，您将给出您的路径，就像我给了There文件夹报告一样，其中保存了DesignationReport.rpt

rptdoc.Load(Server.MapPath(〜\\ Report \\ DesignationReport.rpt"));
rptdoc.SetDataSource(dt);

//crv是Crystal Report查看器的ID
crv.ReportSource = rptdoc;
crv.DataBind();


ExportOptions exportOpts1 = rptdoc.ExportOptions;
rptdoc.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
rptdoc.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
rptdoc.ExportOptions.DestinationOptions = new DiskFileDestinationOptions();
(((DiskFileDestinationOptions)rptdoc.ExportOptions.DestinationOptions).DiskFileName = Server.MapPath("DesignationReport.pdf");
rptdoc.Export();
rptdoc.Close();
rptdoc.Dispose();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType =应用程序/pdf";
Response.AppendHeader("Content-Disposition"，"attachment; filename = DesignationReport.pdf");
Response.WriteFile("DesignationReport.pdf");
Response.Flush();
Response.Close();
System.IO.File.Delete(Server.MapPath("DesignationReport.pdf"));
}
其他
{
Messagebox1.Show(该区域没有记录");
}
}
赶上{}
}

尝试上述代码后，给出反馈
