//我的程序中犯了3个错误。我希望我的所有错误都显示在最后。所以，如果有任何错误，程序会显示错误并关闭控制台，否则，将进行数学运算

            }

            Console.ForegroundColor = ConsoleColor.Gray;

// i want my error show up here. so if there are any error. show up the error and than close the console, but if there are not any error, will do the math.


        }
    }
}

如果你声明你的字符串错误，最好使用：string error = ""; 在你的情况下：error = "My Error!";

并写下来：

Console.WriteLine(error);
Console.ReadLine(); //wait for input from keyboard.
