c# - 控制台应用程序代码错误

Question

在我的代码中，

            int x;
            int y;
            x = 7;



            if (x == y)
            {
                Console.WriteLine("The numbers are the same!");

            }
            else
            {
                Console.WriteLine("The numbers are different.");
            }
            Console.ReadLine();


            for (int i = 0; i < y; i--)
            {
                Console.WriteLine("{0} sheep!", i);
            }
            Console.ReadLine();


            string[] colors = new string[y];
            colors[0] = "green";
            colors[1] = "yellow";
            colors[y] = "red";


            Console.WriteLine("Your new code is {0}.", Code(x, y));
            Console.ReadLine();

        }   

            static int Code(int myX, int myY)
            {
                int answer = myX * myX - myY;
            }
    }
}

有一个错误指出:

'ConsoleApplication1.Program.Code(int, int)': not all code paths return a value'.

我不确定代码有什么问题。解决方案？

Answer 1

非常简单。你的功能:

static int Code(int myX, int myY)
{
    int answer = myX * myX - myY;
}

要求您返回一个整数。我想你是想这样做:

static int Code(int myX, int myY)
{
    return myX * myX - myY;
}
