Generic DBNull function

Hi folks,

I usually use c# so I'm stuck on this.

I want a generic method that can handle dbnull's and return the default value for the type

I'n c# you can use the default key word but I can't find any vb version.

The following is what I would want to wrap up into a single method but without using lots of if, cases and gettypes if possible.

Public Function IntegerDefault(ByVal i As Integer) As Integer
        If (IsDBNull(i)) Then
            Return -1
        Else
            Return i
        End If
    End Function

    Public Function StringDefault(ByVal s As String) As String
        If (IsDBNull(s)) Then
            Return ""
        Else
            Return s
        End If
    End Function

Cheers
Jon
