Trackback with C#

        private void Button1_Click(object sender, System.EventArgs e)
        {
            HttpWebRequest HttpWReq=(HttpWebRequest)WebRequest.Create("http://tb.donews.net/TrackBack.aspx?PostId=527773");
            HttpWReq.Method="POST";
            HttpWReq.ContentType="application/x-www-form-urlencoded";

        //    string p="title=引用到的文章标题&url=引用到的地址&excerpt=正文&blog_name=作者";
            string p="title=title1&url=http://www.gmail.com&excerpt=mainpart&blog_name=me";
            ASCIIEncoding encoding=new ASCIIEncoding();
            byte[]  byte1=encoding.GetBytes(p);
            Stream sm=HttpWReq.GetRequestStream();
            sm.Write(byte1,0,byte1.Length);
            sm.Close();
            HttpWebResponse HttpWResp = (HttpWebResponse)HttpWReq.GetResponse();
            StreamReader sr = new StreamReader(HttpWResp.GetResponseStream());
    //        StreamReader sr = new StreamReader(HttpWResp.GetResponseStream(),Encoding.GetEncoding("GB2312"));
            foreach(string i in HttpWReq.Headers)
            Response.Write(i+"="+HttpWReq.Headers[i]+"<br>");
            Response.Write(sr.ReadToEnd());
            HttpWResp.Close();
        }

说实话真觉得不如在脚本中方便。
看着sm.Write(byte1,0,byte1.Length);就觉得不爽。
xmlhttp.send("title=title1&url=http://www.gmail.com&excerpt=mainpart&blog_name=me");多直接！
