验证码比较难获得，即使获取了验证码，也不好把值赋值给session,因为session是服务器端的，期待高手。这里有一个post数据的例子，供参考！ public static string GetWebContent(string _firstname, string _lastName, string _sex, string _year, string _month, string _day)
    {
        string html = "";
        try
        {
          
            //--------------------------------------------------------------------------------------------------------------
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@"http://sina.sm.aqioo.com/XingMingPingFen.html?");
            byte[] data = Encoding.UTF8.GetBytes(string.Format("txtMFirstName={5}&txtMLastName={0}&sex1={1}&year1={2}&month1={3}&day1={4}", _lastName, _sex, _year, _month, _day, _firstname));            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;            Stream writer = request.GetRequestStream();
            writer.Write(data, 0, data.Length);
            writer.Close();            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
            html = reader.ReadToEnd();            reader.Close();
            response.Close();
            return html;
        }
        catch
        {
            return ("出错");
        }
    }
