c#窗体应用程序通过HTTP协议访问服务器,来验证用户名和密码

用C#写的一个登录程序，我用php写的一个网站，想通过http协议来完成登录客户端到网页的一个用户名和密码的验证，我是菜鸟，求大神们写下详细代码

}追问

比如这个登陆框，我想传递用户名和密码到服务器（php文件）中，然后服务器判断用户名和密码是否正确，返回一个参数。想知道这个代码，不用写那么复杂，能不能帮我简化一点，只写个传递到服务器就好。

追答

System.Net.ServicePointManager.Expect100Continue = false;

到

Console.WriteLine("网关注册成功！"); 之间的代码是必需的。

回复不了，说字数限制，只能上面简单点
