I try to create a string extension with the method Space(int) in it. If I have an instance of a string, then its no problem. But without I have no Idea.

The call should be: string.Space(2) or String.Space(2)

Not "".Space(2)!!!

In this example, the method should return 2 space characters (" ").

Anybody to help?

>Solution :

An extension method is supposed to act on an object instance, that’s how and why it has the syntax it got.

But in your case, your method does not act on a string instance, so what’s the point of trying to define it as a string extension method? Just keep it an old boring static method. There’s nothing wrong with ye’ole static methods…
