private string HttpPost(string Url, string postDataStr) 
    { 
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); 
      request.Method = "POST"; 
      request.ContentType = "application/x-www-form-urlencoded"; 
      request.ContentLength = Encoding.UTF8.GetByteCount(postDataStr); 
      request.CookieContainer = cookie; 
      Stream myRequestStream = request.GetRequestStream(); 
      StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312")); 
      myStreamWriter.Write(postDataStr); 
      myStreamWriter.Close(); 
 
      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
 
      response.Cookies = cookie.GetCookies(response.ResponseUri); 
      Stream myResponseStream = response.GetResponseStream(); 
      StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8")); 
      string retString = myStreamReader.ReadToEnd(); 
      myStreamReader.Close(); 
      myResponseStream.Close(); 
 
      return retString; 
    } 
 
    public string HttpGet(string Url, string postDataStr) 
    { 
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr); 
      request.Method = "GET"; 
      request.ContentType = "text/html;charset=UTF-8"; 
 
      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
      Stream myResponseStream = response.GetResponseStream(); 
      StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8")); 
      string retString = myStreamReader.ReadToEnd(); 
      myStreamReader.Close(); 
      myResponseStream.Close(); 
 
      return retString; 
    }

在post的時刻有時也用的到cookie，像登錄163發郵件時刻就須要發送cookie，所以在內部一個cookie屬性隨時保留 CookieContainer cookie = new CookieContainer();

留意：有時刻要求會重定向，但我們就須要從重定向url獲得器械，像QQ登錄勝利後獲得sid，但下面的會主動依據重定向地址跳轉。我們可以用：

request.AllowAutoRedirect = false;設置重定向禁用，你便可以從headers的Location屬性中獲得重定向地址
