Visual Studio的输入小问题

vs中的控制台程序,如何让输入的东西显示为*号,不管怎都谢谢，看本问题的人，棒棒哒

 // Backspace Should Not Work
if (key.Key != ConsoleKey.Backspace && key.Key != ConsoleKey.Enter)
{
   pass += key.KeyChar;
   Console.Write("*");
}
else
{
   if (key.Key == ConsoleKey.Backspace && pass.Length > 0)
   {
      pass = pass.Substring(0, (pass.Length - 1));
      Console.Write("\b \b");
   }
}
