参数设置 HttpWebResponse response = (HttpWebResponse)httprequest.GetResponse();//使用HttpWebResponse获取请求的还回值 Stream steam = response.GetResponseStream();//从还回对象中获取数据流 StreamReader reader = new StreamReader(steam, Encoding.GetEncoding("gb2312"));//读取数据Encoding.GetEncoding("gb2312")指编码是gb2312，不让中文会乱码的 PageStr = reader.ReadToEnd(); reader.Close();

//Post请求方式，于Get的方式写法相似，所以解释就些少一点了
