C#控制台 用*号显示密码输入

Code
 static void Main(string[] args)
        {
            ArrayList al = new ArrayList();
            ConsoleKeyInfo cki = Console.ReadKey(true);
            while (cki.Key.ToString() != "Enter")
            {
                al.Add(cki);
                Console.Write("*");
                cki = Console.ReadKey(true);
            }

            Console.WriteLine();

            foreach (object o in al)
            {
                cki = ((ConsoleKeyInfo)o);
                Console.Write(cki.KeyChar);
            }
            Console.ReadLine();
        }
    }

//泛型实现：

        static void Main(string[] args)
        {
            List<ConsoleKeyInfo> ls = new List<ConsoleKeyInfo>();
            ConsoleKeyInfo cki = Console.ReadKey(true);
            while (cki.Key.ToString() != "Enter")
            {
                ls.Add(cki);
                Console.Write("*");
                cki = Console.ReadKey(true);
            }

            Console.WriteLine();

            foreach (ConsoleKeyInfo o in ls)
            {
                Console.Write(o.KeyChar);
            }
            Console.ReadLine();
