   public static int StaticProperty
   {
      set { myValue = value; }
      get { return myValue; }
   }

}

class MainClass
{
   static void Main()
   {

      MyClass.StaticProperty = 10;
      Console.WriteLine("New Value : {0}", MyClass.StaticProperty);
   }
}

class Color/*from  w  w w  . j a v a2s.c  o m*/
