C# 在代码里调用其他Webapi

Get方法 （url拼接方式传值）

try
            {
                var url = "www.baidu.com";
                WebClient MyWebClient = new WebClient();
                MyWebClient.Credentials = CredentialCache.DefaultCredentials;
                Byte[] pageData = MyWebClient.DownloadData(AiNengLocation_Url);
                MemoryStream ms = new MemoryStream(pageData);
                using (StreamReader sr = new StreamReader(ms, Encoding.GetEncoding("UTF-8")))
                {
                    returnValue = sr.ReadLine();
                }
                if (returnValue != null && returnValue != "")
                {
                    #region 解析返回接口
                    var all = JsonConvert.DeserializeObject<IDictionary<string, object>>(returnValue);

                    var neList = JsonConvert.SerializeObject(all["xxxx"]);

                    JavaScriptSerializer Serializer = new JavaScriptSerializer();
                    List<RealModel> objs = Serializer.Deserialize<List<RealModel>>(neList);//RealModel是类对象
                    #endregion
                }
            }
            catch (Exception e)
            {
            }

Post方法(用json方式传值)

 var url = "http://xxxx:123/api/Aaa";
            string strData = "[{"name":"" + "tag" + "","value":" + "11" + ","datetime":"" + "1999-01-01 00:00:00" + ""}]";
            string result = "";
            //将实时数据转发到一级平台
            HttpWebRequest wbRequest = (HttpWebRequest)WebRequest.Create(url);
            wbRequest.Method = "POST";
            wbRequest.ContentType = "application/x-www-form-urlencoded";
            string paramData =
                "data=" + strData;
            byte[] byteArray = Encoding.UTF8.GetBytes(paramData);
            wbRequest.ContentLength = byteArray.Length;
            IDictionary<string, object> all;
            try
            {
                using (Stream requestStream = wbRequest.GetRequestStream())
                {
                    using (StreamWriter swrite = new StreamWriter(requestStream))
                    {
                        swrite.Write(paramData);
                    }
                }
                HttpWebResponse wbResponse = (HttpWebResponse)wbRequest.GetResponse();
                Stream stream = wbResponse.GetResponseStream();
                //获取响应内容
                using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
                {
                    result = reader.ReadToEnd();
                }
                all = JsonConvert.DeserializeObject<IDictionary<string, object>>(result);
            }
            catch (Exception e)
            {
            }
