VB.net Automatically convert a Nothing value into something else


In VB.net is there a way to automatically convert a "Nothing" value into something else?
For example if I have
Dim oString = X
where X is nothing
How do I automatically assign a blank string "" to that
In Access VBA it would be oString = nz(X,"")

If you want to assign an empty string as a default value, rather than nothing use

Dim oString As String = ""

What about this
If String.IsNullOrEmpty(oString) Then
    oString = "Something"
End If

Try this:
