Question

Is there a better way to require that an argument is not null in a method? I keep checking if any of the arguments that my method requires are null, as show below. But I’m wondering if there is a better way.

public void MyMethod(string a, int b) {    if(a==null){throw new ArgumentNullException('a');}    if(b==null){throw new ArgumentNullException('b');}     //more stuff here }
