What thing you have to remeber while dealing with static member?

A static member cannot be marked as override, virtual, or abstract.

Take this example

class  Base
    {
        public static virtual  void  fun()
        {
            Console.WriteLine("Base");
        }
     }
  class child : Base
    {
     public   override void fun()  //error: Static methods never be override
        {
            Console.WriteLine("child");
        }
       }
