试图给用户反馈时的循环

Question

我想用 "while "功能，让用户每次输入错误的用户名或密码时，CMD都会告诉用户 "用户名错了。"或者 "密码错了"。我现在算是做到了，用户可以多次输入，直到得到正确的答案，问题是CMD并没有告诉用户他们使用的用户名密码是错误的! 我将把整个代码贴在这里。

namespace Hello
{
    class Program
    {
        static void Main(string[] args)
        {

            string name = "Michael";
            string pass = "coolguy";
            int time = 12;
            string NameInput;
            string PassInput;
            string Exit = "Y";
            string ExitInput;

            Console.Write("\nPlease, enter the time: ");
            time = int.Parse(Console.ReadLine());
            if (time <= 12)
            {
                Console.WriteLine("\nGood Morning. It's " + time + " AM");
            }

            else if (time > 12)
            {
                Console.WriteLine("\nGood Evening. It's " + time + " PM");
            }

            Console.WriteLine("\nPlease, enter your name.");
            do NameInput = Console.ReadLine();
            while (NameInput != name);

            Console.WriteLine("\n Welcome, Michael. Please, enter your password: ");
            do PassInput = Console.ReadLine();

            while (PassInput != pass);

            Console.WriteLine("\nYou successfully have logged in.");
            Console.WriteLine("\nType (Y) to log out.");
            ExitInput = Console.ReadLine();
            if (ExitInput == Exit)
            {
                return;
            }



        }
    }
}

通过在 "do-while "语句里面嵌套一个 "if "语句来修正。

Console.WriteLine("\n Welcome, Michael. Please, enter your password: ");
        do
        {
            PassInput = Console.ReadLine();
            if(PassInput != pass)
            {
                Console.WriteLine("\nWrong password.");
            }

        } while (PassInput != pass);
