使用水晶报告导出为pdf文件
我在这里有代码示例，我可以直接保存为PDF文件，但我想要做的是显示客户端的第一个pdf文件，并允许用户保存它。 我该如何实现这一目标？
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();
像这样的代码………..
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");
