C#在WinFrom程序实现Get和Post请求及QQ农场的Cookie保存

意Cookie的绑定，此处Cookie为获取验证码时记录的Cookie值。
 

以下是实现代码：

#region 提交数据方法       // 公用Cookie信息       public static CookieContainer myCookie;       //返回的Html代码或结果       public static string html;       /// <summary>       /// Get方式提交       /// </summary>       /// <param name="strUrl">目的资源链接</param>       /// <returns>String:Response返回值</returns>       public static string GetModel(string strUrl, string server)       {           string strRet = null;           try           {               HttpWebRequest request = (HttpWebRequest)WebRequest.Create(strUrl);               request.Timeout = 2000; HttpWebResponse response = (HttpWebResponse)request.GetResponse();               System.IO.Stream resStream = response.GetResponseStream();               Encoding encode = System.Text.Encoding.UTF8;               StreamReader readStream = new StreamReader(resStream, encode);               Char[] read = new Char[256];               int count = readStream.Read(read, 0, 256);               while (count > 0)               {                   String str = new String(read, 0, count);                   strRet = strRet + str;                   count = readStream.Read(read, 0, 256);               }               resStream.Close();           }           catch (Exception e)           {               strRet = "";           }           return strRet;       }       /// <summary>       /// 绑定Cookie、获取验证码       /// </summary>       /// <param name="strUrl">链接地址（验证码获取地址）</param>       /// <param name="server">Referer地址</param>       /// <returns>Stream:验证码的数据流</returns>       public static Stream GetModelStream(string strUrl, string server)//, string proxy, bool isProxy)       {           System.IO.Stream resStream = null;           string cookie;           try           {               HttpWebRequest httpRequest = (HttpWebRequest)HttpWebRequest.Create(strUrl);               httpRequest.Timeout = 2000;               httpRequest.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";               httpRequest.Referer = server;               httpRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322)";               HttpWebResponse httpResponse = (HttpWebResponse)httpRequest.GetResponse();               cookie = httpResponse.Headers.Get("Set-Cookie");               myCookie = new CookieContainer();               myCookie.SetCookies(new Uri(server), cookie);               resStream = httpResponse.GetResponseStream();           }           catch { }           return resStream;       }       /// <summary>       /// Post方法提交       /// </summary>       /// <param name="strUrl">目的资源链接</param>       /// <param name="strParm">传递的参数和值</param>       /// <returns>String:Response返回值</returns>       public static string PostModel(string strUrl, string server, string strParm)       {           Encoding encode = System.Text.Encoding.UTF8;           byte[] arrB = encode.GetBytes(strParm);           HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(strUrl);           myReq.Method = "POST";           myReq.ContentType = "application/x-www-form-urlencoded";           myReq.Timeout = 2000;           myReq.Referer = server;           myReq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322)";           myReq.ContentLength = arrB.Length;           myReq.CookieContainer = myCookie;           Stream outStream = myReq.GetRequestStream();           outStream.Write(arrB, 0, arrB.Length);           outStream.Close();           WebResponse myResp = null;           try           {               //接收HTTP做出的响应                      myResp = myReq.GetResponse();           }           catch (Exception e)           {           }           Stream ReceiveStream = myResp.GetResponseStream();           StreamReader readStream = new StreamReader(ReceiveStream, encode);           Char[] read = new Char[256];           int count = readStream.Read(read, 0, 256);           string str = null;           while (count > 0)           {               str += new String(read, 0, count);               count = readStream.Read(read, 0, 256);           }           readStream.Close();           myResp.Close();           return str;       }       #endregion
