遇到一个比较严重的问题！！！！

我在c#中
///<summary>
/// 处理请求
/// </summary>
/// <returns>返回当前处理的文本</returns>
  public string Proc() 
  {
 
   HttpWebRequest 请求=CreateRequest();//请求
   HttpWebResponse 响应=null;;  
   System.IO.StreamReader sr=null;   
   try
   {
    //这里得到响应
   
    响应 =(HttpWebResponse)请求.GetResponse();
            
    sr=new System.IO.StreamReader(响应.GetResponseStream(),this.encoding);
    
    this._ResHtml=sr.ReadToEnd();    }
   catch (System.Exception ex)
   {
    this._strErr=ex.Message;//发生错误就返回空文本
    return "";
   }      
   //得到cookie
   if( 响应.Cookies.Count > 0)
   {
    this._cookieGet =响应.Cookies;
   }
   return this.ResHtml ;
  }
里面获得的Cookies是：AspNetForums-UserCookie=; AspNetRoles=6C3DF1A3360335513D32AB5F92B6D893BE10A8F0CB3B8E1F2DEF9875897139798531490A8C7613D7A95C6E7D8FB23A852F2E5E89637795D34CC332A65E2230F1EE42984A667FBACBD17511C8A75BD360; AspNetAnonymous=;

而我在网页中截取到的Cookies是：cck_lasttime=1132112110296; cck_count=1; AspNetForums-UserCookie=; AspNetRoles=6C3DF1A3360335513D32AB5F92B6D893BE10A8F0CB3B8E1F2DEF9875897139798531490A8C7613D7A95C6E7D8FB23A852F2E5E89637795D34CC332A65E2230F1EE42984A667FBACBD17511C8A75BD360; AspNetAnonymous=; TxNet=CB656CBF7206E97A050E09060855226929DF0028BD5D87B0C57F67045961D433CC53453EC193D381144F0AE10B9FAF441E777AF97772B2E9B97EF21D6EE602F2EA641223521DC5C17FB89D0A00FDB15
