# Why?

I think it would be helpful if you'd explain why these approaches are better. Is something inherently better about a static method call versus providing a string literal? Are you suggesting this changes the behavior of string interning? Thanks.

From a performance point of view, Setting: (String.Length == 0) is twice as fast as using String.Empty.

If you've used FxCop one of the performance rules states that, Constructs such as "".Equals(someString) and String.Empty.Equals(someString) are less efficient than testing the string length. Replace these with checks for someString.Length == 0. Check it out here:

i suggest using Dim StranEmpty As String = "" is better and faster than using
Dim StranEmpty As String = String.Empty
