     Console.ReadLine();

  }

   public static void ranguess()
  {
     int yn, rn; 
     int con=1; 
     Random rd = new Random(); //create random object
     while (con == 1)
      {
         Console.Write("Enter your guess number:");
         yn = int.Parse(Console.ReadLine());
         rn =rd.Next(1,7);//generate random number from 1 t 6
         Console.WriteLine(rn);
        if (yn == rn)
        {
          Console.WriteLine("You won.");

        }
      else
        {
           Console.WriteLine("You lost.");
           Console.WriteLine("My number is {0}.", rn);

        }

       Console.Write("Press 1 to continue:");
       con = int.Parse(Console.ReadLine());


    }

  }
