Converting empty strings to Null

An empty string is not the same as a null (in practically any language).  Tell us what you're trying to do (perhaps there is a better way to accomplish the goal).

Converting that to VB.NET, you can use: Return vbnull and Return str instead of getnull = vbnull and getnull = str.

Mayank.

Public Function ConvertStr(ByVal str As String) As String
        If IsNothing(str) Then
            ConvertStr = str
        ElseIf str.Length = 0 Then
            ConvertStr = Nothing
        Else
            ConvertStr = str
        End If
    End Function
