一个关于C#利用HTTP传输xml字符串的有关问题

一个关于C#，利用HTTP传输xml字符串的问题
刚接触项目，有个问题请教下各位大侠~对方要求将解析完的xml利用http传给他，url已给，http://ip:port/nms/upload，然后我序列化的部分也做完了：
         public string Serialize()
        {
            string strSource = "";
            try
            {
                Snapshot = null;
                XmlSerializer s = new XmlSerializer(typeof(MSG_PU_VIDEO_DEVICE_ALARM));
                Stream stream = new MemoryStream();
                s.Serialize(stream, this);
                stream.Seek(0, SeekOrigin.Begin);
                using (StreamReader reader = new StreamReader(stream))
                {
                    strSource = reader.ReadToEnd();
                }

            }
            catch (Exception ex)
            {
                throw ex;
            }
            return strSource;
            }
        
        public static MSG_PU_VIDEO_DEVICE_ALARM Deserialize(string xmlSource)
        {
            MSG_PU_VIDEO_DEVICE_ALARM obj = new MSG_PU_VIDEO_DEVICE_ALARM();
            try
            {
                XmlSerializer x = new XmlSerializer(typeof(MSG_PU_VIDEO_DEVICE_ALARM));
                Stream stream = ProtocolHelper.GetStream(xmlSource);
                stream.Seek(0, SeekOrigin.Begin);
                obj = (MSG_PU_VIDEO_DEVICE_ALARM)x.Deserialize(stream);
                stream.Close();
            }
            catch (Exception ex)
            {
                throw ex;
            }
            return obj;
        }
        }
然后我将如何将序列化完的结果传出去呢，可以给个或者写个简单的demo呢，谢谢啦！
------解决方案--------------------
把XML保存为文本文件,再上传就好了.
