Generic type checking

Question

Is there a way to enforce/limit the types that are passed to primitives? (bool, int, string, etc.)

Now, I know you can limit the generic typ

@Rob, Enum's will slip through the TypeValid function as it's TypeCode is Integer. I've updated the function to also check for Enum.

Private Function TypeValid() As Boolean
    Dim g As Type = GetType(T)
    Dim code As TypeCode = Type.GetTypeCode(g)

    ' All of the TypeCode Enumeration refer Primitive Types
    ' with the exception of Object and Empty (Nothing).
    ' Note: must also catch Enum as its type is Integer.
    Select Case code
        Case TypeCode.Object
            Return False
        Case Else
            ' Enum's TypeCode is Integer, so check BaseType
            If g.BaseType Is GetType(System.Enum) Then
                Return False
            Else
                Return True
            End If
    End Select
End Function
