String.IsNullOrWhiteSpace 02/11/2011 Gérald Barré .NETA new feature in the framework .NET 4.0: String.IsNullOrWhiteSpace(string value). It comes in addition to the function String.IsNullOrEmpty(string value). I think there's no need to clarify what it does, the name is quite explicit.Even in the base classes there are some new features 😃 Do you have a question or a suggestion about this post?
