If you want to check if your variable is not 'Nothing' and does not

This is my recommended way too. For all the new features and functionality offered in .NET, I'll still go for good ol' Len() every time.

The Len function is just a wrapper for the String.Length method.

If s.Length > 0 Then
...
End If

No, it's more than that. It will return 0 if the value passed to it is 'Nothing'. The code you posted would throw a 'NullReferenceException' in this case.


Yes, ok, it's almost only a wrapper.
