Static Class & Static Method

Question

静态类中的静态方法和非静态类中的静态方法有什么不同？

Answer 1

There is no difference.
Not between the methods anyway.

Answer 2

For the majority of scenarios they are essentially equivalent features. The one notable difference is that only a static method in a static class can be an extension method.

Answer 3

There is no difference.

Unlike a non-static class you cannot modify the static method to be an instance method later, because a static class can only contain static members.

This is not allowed and will not compile

public static class Foo{
    public void test(){}
}

Answer 4

A static class can contain only static methods, whereas a non-static class can contain both. Deciding which way to go is strictly a design issue in C#.
