Override static derived variable


Hello.

I have a problem with C# language. I want to define an algorithm on a static function inside an abstract class. This function calls a static variable inside the same class. Then I want to define some derived classes wich inherit the function and override the variable, but it doesn't work.

Testcase:

using System;

namespace Test
{

  abstract public class X {
    protected static string var = "x";

    public static void print_my_var(){
      Console.WriteLine("my var is " + var);
    }
  }

  public class A : X {
    protected static new string var = "a";
  }

  public class B : X
  {
    protected static new string var = "b";
  }

  class ClassTest {

    [STAThread]
    static void Main(string[] args)
    {
      X.print_my_var();
      A.print_my_var();
      B.print_my_var();
    }
  }
}


result:
my var is x
my var is x
my var is x

expected results:
my var is x
my var is a
my var is b

How can obtain the expected results using static methods and static variables and without creating the static method A or B?

Thanks in advance.

	Andrew
