C# Memory usage of classes

Given is a class with several static and several internal methods.

As far as i know, the static ones are only created once, no matter how many instances of the class i have, right?
Consequently the internal methods should be created every time one creates an instance of this class, right?
Would it then not be better to declare all methods of a class as static and hand them over the instance of the class every time we call them?

Well, yes and no. It'd be procedural programming then. You get that when you use C and have only a bunch of methods and pass structures around :)

I doubt that when you instantiate a class that all the methods are copied in memory, too. Why are you worrying about this?

Making methods static has no effect on memory.  The code for a class only exists once, whether static or not.  The _fields_ of a class, however, will only exist once if they are static.  

The only reason to make a _Method_ static is if does not use any instance data.
