what the point of declaring a static method in a non-static class?

Question

The way I understand it, having a member variable declared as static in a no-static class causes that member variable to be unique no-matter the number of instances of that class.

Now, what happen to a static method declared in non-static class? And (Most importantly), what the point of declaring a static method in a non-static class?

Thanks for helping

Answer 1

If the method has something to do with the type but not the instance then it can be static.

DateTime.Parse and Int32.Parse are examples.

Answer 2

It's useful for creating factory methods which are not members of any object but which need access to the internals of an object in order to initialize it.
