如何用C#登录到这个网站？？？


byte[] PostData = Encoding.Default.GetBytes("user.username=abc&user.password=dsfds&hold=1");


string Interface = "http://www.koubei.com/join/login.html";
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create(Interface);
Request.Method = "POST";
Request.ContentLength = PostData.Length;
Request.ContentType = "application/x-www-form-urlencoded";
Request.AllowAutoRedirect = true;
using (Stream sm = Request.GetRequestStream())
{
sm.Write(PostData, 0, PostData.Length);
sm.Close();
}
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
StreamReader sr = new StreamReader(Response.GetResponseStream(), Encoding.Default);
string s = sr.ReadToEnd();



不能正确登录？？？

我隐藏了正确的帐号和密码。。

不用这样的，用 WEBCLIENT

具体代码：

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Collections.Specialized;

namespace CMD_POST
{
    class Program
    {
        String Url = "";  //提交的网址
        String username = "";  //提交的用户名
        String password = "";  //提交的密码
        String Speacl = "";  //用来保存特殊特征码字符串
        static void Main(string[] args)
        {
            Program p = new Program();
            p.Welcome_Word();
            Console.WriteLine();
            Console.Write("请输入您的提交网址 (请带上 http:// ) ： ");
            p.Url = Console.ReadLine();
            Console.Write("请输入您的特殊字符 (其中请不要包含特殊字符)： ");
            p.Speacl = Console.ReadLine();
            Console.Write("请输入您的用户名： ");
            p.username = Console.ReadLine();
            Console.Write("请输入您的密  码： ");
            p.password = Console.ReadLine();
            p.GetResult();
        }

        //欢迎词
        public void Welcome_Word()
        {
            Console.WriteLine("************* 欢迎使用Ｃ＃　ＰＯＳＴ 提交器 *************");
            Console.WriteLine();
            Console.WriteLine("  作者：剑走偏锋 [E.S.T] ");
            Console.WriteLine();
            Console.WriteLine("************* 请输入如下数据 *************");
        }

        //创建对象
        public void GetResult()
        {
            WebClient web = new WebClient();
            NameValueCollection vc = new NameValueCollection();
            vc.Add("username", this.username);
            vc.Add("password",this.password);
            String ReturnMess = "";
            int i = 0;
            try
            {
                byte[] byRemoteInfo = web.UploadValues(this.Url,"POST",vc);
                ReturnMess = Encoding.UTF8.GetString(byRemoteInfo);
                for (i = 0 ; i < ReturnMess.Length ; i++)
                {
                    if (ReturnMess.IndexOf(this.Speacl) > 0)
                    {
                        Console.WriteLine("密码找到了!");
                        Console.WriteLine("帐户：" + this.username + "  密码：" + this.password);
                        break;
                    }
                    //Length += 9;
                }
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine("出现错误 ： 请检查您所输入的信息是否正确......");
            }
        }
    }
}
