c# extend String Class with static method

Question

I was wondering if there is a way to extend the string class with a method called GenerateRandom() which generates a random string. Maybe this would look like

string.CreateRandom();

As I have read there is no way than creating an instance of a string and then calling the extension method. Maybe there is one and you know it.

Thanks for your help!

You can't add extension method to a static class. – Ofir Winegarten Apr 07 '17 at 13:07 — Ofir Winegarten, Apr 07 '17 at 13:07

You can't.

The same question was asked here: Static extension methods

You can also read there, why you cannot do that.
