Abstract Vs. Static

Can you create abstract function as Static?
A static member cannot be marked as override, virtual, or abstract.

Can you create static function in Abstract class?
Yes.

Example: 
namespace ConsoleApplication2
{
    public abstract class ps
    {
        public ps()
        {
        }
        public ps(string a)
        {

        }
        public abstract string getMessage();
        public static void Helloworld() { Console.WriteLine("hello"); }

         //A static member cannot be marked as override, virtual, or abstract
        //public static abstract void Helloworld() { Console.WriteLine("hello"); }
        //public static abstract string GetName();

    }

    public class Program :ps
    {
        static void Main(string[] args)
        {
            Program p = new Program();
            Console.WriteLine(p.getMessage());
            Helloworld();
            Console.Read();
        }

        public override string getMessage()
        {
            return "message hello.";
        }
    }

}
