C # class code loaded in RAM?

I would like to know if the actual C # class code is loaded into RAM when creating the class instance?

So, for example, if I have 2 classes CLASS A, CLASS B, where class A has 10,000 lines of code, but only 1 field, int. And class B has 10 lines of code, as well as 1 int int field. If I create an instance of class A, will it take more memory than class B because of its lines of code?

Additional question: if lines of code are loaded into memory along with the class, will they be loaded for each instance of the class? or only once for all instances?

Thanks in advance.
