int x; double y;
            string s;
            s = Console.ReadLine();
            if (int.TryParse(s))
                x = int.Parse(s);
            else
                y = double.Parse(s);
            int a, b; double c, d;
            a = int.Parse(Console.ReadLine());
            b = int.Parse(Console.ReadLine());
            c = double.Parse(Console.ReadLine());
            d = double.Parse(Console.ReadLine());

错误    1    “TryParse”方法没有任何重载采用“1”个参数   

  应该如何解决？
