What is the difference between Const and Static in C#?

Question

I am eager to know the difference between a const variable and a static variable.

Answer 1

As you say, both static and const are attached to a type rather than an instance of a type. However, you can still change static items. You cannot change const items.

Be careful with this, though. If your const item is a reference type, the assigned expression has to be evaluated at compile time, and that means that the only possible value you can give the reference is null (with the notable and useful exception of strings).
