As you may or may not know, static methods are usually faster than instance methods. This alone should be a good enough reason to use the static string.Equals method in .NET, but if that doesn’t do it for you, allow me to present a simple example. string a = "hello"; string b = "hi"; bool result = a.Equals(b); What is the expected result of these lines? A boolean value of false, of course. And it’d be true if the strings were identical. It’s also false if b is null. But what if a is null?
