Refactoring Guard Clauses

A lot of projects that I’ve seen use a static Guard class.

public static class Guard {
    public static void ArgumentIsNotNull(object value, string argument) {
        if (value == null)
            throw new ArgumentNullException(argument);
    }
}

It makes the code a lot cleaner, in my opinion.

Guard.ArgumentIsNotNull(arg1, "arg1");
