如何创建C#登录处理程序

using System;

public class LoginHandler
{
    public bool Login(string username, string password)
    {
        if (username == "admin" && password == "password")
        {
            Console.WriteLine("登录成功！");
            return true;
        }
        else
        {
            Console.WriteLine("用户名或密码错误！");
            return false;
        }
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        Console.WriteLine("请输入用户名：");
        string username = Console.ReadLine();
        Console.WriteLine("请输入密码：");
        string password = Console.ReadLine();

        LoginHandler loginHandler = new LoginHandler();
        loginHandler.Login(username, password);
    }
}
