I love the new String.IsNullOrEmpty() method; however, I need something that will go one step further. I want to know when a string is null, empty, or only has white space characters in it. The custom library that I've been working on for several years uses IsEmpty() to check null/empty and IsBlank() to check for null, empty, and whitespace. Give me something like that. This could be very helpful and encourage people to check for whitespace. All to many times I see whitespace-accepting textboxes in applications. Having such a handy feature might help alleviate that. While I would like to see String.IsEmpty() and String.IsBlank() methods, which are less wordy, I'd be happy with something like String.IsNullOrEmpty(string, bool) where the second parameter would indicate whether to trim the content.
