Nullable Types in .NET Objects


I want to produce a report using an arraylist of .net objects as datasource. For this I defined a public class in my project having some properties. Now my question is: Is it possible to use nullable types as types for the properties? E.g. is it possible to use "int?" or "long?" as type for a property?

If not, is it planned to support nullable types in the next release of crystal reports?

Thank you for your help!

Best Regards,

Joachim Lukasser

    I don't know. Have you attempted this at all? If so, did you get errors or other issues?

    I'd also recommend looking at the CHM file for the CR SDK. As you have not given me the version of CR you are working with I'm guessing either CR XI r2:

    C:\Program Files\Business Objects\Crystal Reports 11.5\Help\en\crsdk_net_doc\doc\crsdk_net_doc.chm

    Or CR 2008:

    Search for "Connecting to Object Collections"
