用C# HttpWebRequest时，本地IP可以伪造吗？ (除了用代理IP方法外)

            Stream stream = null;

            HttpWebResponse response = null;

            HttpWebRequest request = null;

   

    

                

                request = WebRequest.Create(string.Format("http://xx.New") as HttpWebRequest;              

                string strPostData = "name=游客&SEX=0";

                byte[] wrBuffer = Encoding.GetEncoding("gb2312").GetBytes(string.Format(strPostData));



                request.Method = "POST";

                request.ContentType = "application/x-www-form-urlencoded";

                request.ContentLength = wrBuffer.Length;

               // request.Referer = string.Format("http://xx.cn/");

                request.UserAgent = "MSIE 6.0";

                request.Timeout = 8000;

                



               



                ////设置一个代理 

                  //System.Net.WebProxy myproxy = new System.Net.WebProxy("218.63.252.219", 80);

                //request.Proxy = myproxy;

               

                stream = request.GetRequestStream();

                stream.Write(wrBuffer, 0, wrBuffer.Length);

                stream.Close();



                response = request.GetResponse() as HttpWebResponse;

                stream = response.GetResponseStream();

                StreamReader sr = null;

                sr = new StreamReader(stream, big5);

                sr.Close();

                stream.Close();
