c# StringExtension with Method Space-CodePudding

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?

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...

Thank you Sweeper:

namespace Exp.Util.Extension 
{
    public static class IntegerExtension 
    {
        public static string ToSpaces(this int aData) 
        {
            return new string(' ', aData);
        }
    }
}

For this concrete example I think you can simply work with the string constructor:

var spaces = new string(' ', 2);
