导出为PDF文件使用水晶报告

本文关键字：水晶 报告 文件 PDF | 更新日期: 2023-09-27 18:18:30

我这里有代码样本，我可以直接保存为PDF文件，但我想做的是显示客户端第一PDF文件，并允许用户保存它。我该如何做到这一点?

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();

下面是我的代码:

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");

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...........
