Question

The value (parameter) of ABC can be NULL. I’m struggling with how to set it to null. The statement below is not working. If I trying to set type Nullable(OfInteger), I get the error that the value is the ‘wrong type.’ Thanks in advance.

 Dim ABC as Integer = Nothing

 Public Function RunStoredProce(ByVal **ABC** As Integer, ByVal DEF As String) _
               As IEnumerable(Of MyProjectStoredProcResults) Implements MyFunction.GetThatDataResult

        Dim y = (From p In dc.uspReportMyFunction(**ABC**, DEF)
            Select p).ToList

        Return y

    End Function

Answer 1

Dim ABC As Nullable(Of Integer)

Public Function RunStoredProce(ByVal ABC As Nullable(Of Integer), ByVal DEF As String) _
           As IEnumerable(Of MyProjectStoredProcResults) Implements MyFunction.GetThatDataResult

    Dim y = (From p In dc.uspReportMyFunction(ABC, DEF)
        Select p).ToList

    Return y

End Function

I believe linqtosql will handle the nullable translation automatically.
