我的代码对数字进行阶乘，但由于某种原因，每当我输入 13 或更高的数字时，它要么给出错误的数字，要么以某种方式得到负数。有什么建议么？

        List<int> myList = new List<int>();
        Console.WriteLine("My Job is to take the factorial of the number you give");
        Console.WriteLine("What is the number?");
        string A = Console.ReadLine();
        int C = Convert.ToInt32(A);
        int k = C;
        int B = C;
        int U = C - 1;
        Console.Write("{0} ", B);
        while (U != 0)
        {
           k *= U;
           Console.Write("* {0} ", U);
            U--;
        }
        Console.WriteLine(" = {0}", k);
        Console.ReadLine();
