I want to know if you find methods to avoid save the temp pdfs, that will waste a lot of useless space. Thanks. – fish-404
I find the temp files seems mandatory. And I add a logic to delete them. – fish-404

Something like this

 {
        ExportOptions CrExportOptions ;
        DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
        PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();
        CrDiskFileDestinationOptions.DiskFileName = "c:\\csharp.net-informations.pdf";
        CrExportOptions = cryRpt.ExportOptions;
        {
            CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
            CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
            CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
            CrExportOptions.FormatOptions = CrFormatTypeOptions;
        }
        cryRpt.Export();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
