2105311 - ExportToStream throws exception in SP 12 in Crystal Reports for Visual Studio

Exception "Unable to cast object of type 'FileStreamDeleteOnClose' to type 'System.IO.MemoryStream'." with SP12 version

Crystal Reports for Visual Studio .NET - Service Pack 12

• Use the following code to export a report:

 

Dim Report As New ReportDocument
Dim oStream As New MemoryStream

Report.Load(reportPath + reportName)
Report.FileName = reportPath + reportName
Report.Database.Tables(0).SetDataSource(dataTableName)

oStream = CType(Report.ExportToStream(ExportFormatType.PortableDocFormat), MemoryStream)

• Export to memory stream was never supported by the CrystalDecisions.CrystalReports.Engine.ReportDocument.ExportToStream API

 

 

• This issue will not be "fixed".
• There are no enhancements planned at this time.

• CrystalDecisions.CrystalReports.Engine.ReportDocument.ExportToStream only returns System.IO.Stream.

• For more information see the Crystal Reports .NET API Guide:

 

 

• Use:

    System.IO.Stream stream = reportDocument.ExportToStream (CrystalDecisions.Shared.ExportFormatType.PortableDocFormat)
