C#求助

Question

帮我看看下面的代码，为什么总是提示字符类型格式不对啊！
 Console.WriteLine("我是一个简单的计算器，可以实现两个整数的加、减、乘、除、取余");
            Console.WriteLine("请输入第一个操作数：");
             int no1 = int.Parse(Console.ReadLine());
            Console.WriteLine("请输入第二操作数：");
             int no2 = int.Parse(Console.ReadLine());
            Console.WriteLine("请运算符<+ - * / %>：");
            string type = Console.ReadLine();
            if (type == "+"){
                Console.WriteLine("{0}加上{1]等于{2}", no1, no2,no1 + no2);
            }
            else if (type == "-"){
                Console.WriteLine("{0}减{1]等于{2}", no1, no2, no1 - no2);
            }
            else if (type == "*")
            {
                Console.WriteLine("{0}乘以{1]等于{2}", no1, no2, no1 * no2);
            }
            else if (type == "/")
            {
                if (no2 == 0)
                {
                    Console.WriteLine("输入错误！除数不能为0");
                }
                else
                {
                    Console.WriteLine("{0}除以{1]等于{2}", no1,no2,no1 / no2);
                }
            }
            else if (type == "%")
            {
                if (no2 == 0)
                {
                    Console.WriteLine("输入错误！除数不能为0");
                }
                else
                {
                    Console.WriteLine("{0}除以{1]取余等于{2}",no1, no2, no1 * no2);
                }
            }
            else
            {
                Console.WriteLine("输入错误！");
            }
            Console.ReadLine();
