export as a pdf file using crystal report
提问by sakir
I have code sample here, I can save as a PDF file directly but what I want to do is to show client first pdf file, and allow users to save it. How do I achieve this?
我这里有代码示例，我可以直接保存为 PDF 文件，但我想要做的是显示客户端第一个 pdf 文件，并允许用户保存它。我如何实现这一目标？
ReportDocument rpt = new ReportDocument();
rpt.Load(@"C:\CrystalReport2.rpt");
rpt.SetDataSource(datatablesource);
ExportOptions rptExportOption;
DiskFileDestinationOptions rptFileDestOption = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions rptFormatOption = new PdfRtfWordFormatOptions();
string reportFileName = @"C:\SampleReport.pdf";
rptFileDestOption.DiskFileName = reportFileName;
rptExportOption = rpt.ExportOptions;
{
rptExportOption.ExportDestinationType = ExportDestinationType.DiskFile;
//if we want to generate the report as PDF, change the ExportFormatType as "ExportFormatType.PortableDocFormat"
//if we want to generate the report as Excel, change the ExportFormatType as "ExportFormatType.Excel"
rptExportOption.ExportFormatType = ExportFormatType.PortableDocFormat;
rptExportOption.ExportDestinationOptions = rptFileDestOption;
rptExportOption.ExportFormatOptions = rptFormatOption;
}
rpt.Export();

ExportOptions CrExportOptions ;
DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();
CrDiskFileDestinationOptions.DiskFileName = "C:\SampleReport.pdf";
CrExportOptions = doc.ExportOptions;
{
CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
CrExportOptions.FormatOptions = CrFormatTypeOptions;
}
doc.Export();

Here is my code:
这是我的代码：
dbObj = new ConnectDB();
query = "SELECT Student.*, School.*FROM Student where admissionnumber = '" + reg_number + "'";
DataSet ds = dbObj.Fetch_Data(query, "DataView");
ReportDocument rd;
rd = new ReportDocument();
rd.Load(Application.StartupPath + "\StudentReg.rpt");
//rd.Load("StudentReg.rpt");
rd.SetDataSource(ds);
crv.ReportSource = rd;
crv.Refresh();
if(File.Exists(@"D:\" + reg_number + ".pdf"))
File.Delete(@"D:\" + reg_number + ".pdf");
rd.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, @"D:\" + reg_number + ".pdf");
