How to hide content in the console using C#?

In C#, you can use the Console.ReadKey method to hide the user’s input. The specific code is shown below:

using System;

class Program
{
    static void Main()
    {
        Console.Write("请输入密码：");
        
        string password = "";
        ConsoleKeyInfo key;

        do
        {
            key = Console.ReadKey(true);

            if (key.Key != ConsoleKey.Backspace && key.Key != ConsoleKey.Enter)
            {
                password += key.KeyChar;
                Console.Write("*");
            }
            else
            {
                if (key.Key == ConsoleKey.Backspace && password.Length > 0)
                {
                    password = password.Substring(0, (password.Length - 1));
                    Console.Write("\b \b");
                }
            }
        }
        while (key.Key != ConsoleKey.Enter);

        Console.WriteLine();
        Console.WriteLine("您输入的密码是：" + password);
    }
}

When users enter their password in the code above, the console will display asterisks (*) instead of the actual characters entered by the user to hide the password content.
