I had created some string features like String.Try[Method] versions of some standard methods (like TryParse) where I don't care if the string is null or not and it is annoying check for null before calling the method.
StringBuilder fullName = new StringBuilder(); //StringBuilder consume null strings without problem
String a = null;
String b = " abdc ";
String c = " ";
fullName.ToString(); // returns "abdc"
Is it possible merge this features in your library?
