C# Add method to system class

[Eriedor]

Is it possible to add my own method to say the Array system class?

If so how would i go about doing it? can't seem to find anything explaining on t'internet.

 

[toString]

You can do it by creating a new class which 'extends' the Array Class.

class MyArrayClass: Array
{
    public aNewMethod() { 
        blahh; 
    }
}

That way the new class will contain all of the Array methods, plus any new ones you make.
