如何在.net中调用web api,以get方法为例：

 [WebMethod]
        public static string LoadData()
        {
            //创建请求
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://10.0.0.163/api/map/get");

            //GET请求
            request.Method = "GET";
            request.ReadWriteTimeout = 5000;
            request.ContentType = "text/html;charset=UTF-8";
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));

            //返回内容
            string retString = myStreamReader.ReadToEnd();
            return retString;
        } [WebMethod]
