解析Action返回的Json数据

WebRequest和HttpClient的Get、post方式解析：

namespace Fractalist.Benz.Controllers
{
    public class ResolveResultController : Controller
    {
        public void WebRequestPost()
        {
            HttpWebResponse response = null;
            try
            {
                string url = "http://localhost:8022/ResolveResult/PostTest";
                dynamic expando = new System.Dynamic.ExpandoObject();
                expando.name = "gw";
                var jsonInfo = JsonConvert.SerializeObject(expando);
                byte[] byteArray = Encoding.UTF8.GetBytes(jsonInfo);
                //string result = new HttpClient().GetStringAsync(url).Result;
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                request.Method = "POST";
                request.ContentType = "application/json";
                request.ContentLength = byteArray.Length;
                Stream newStream = request.GetRequestStream();
                newStream.Write(byteArray, 0, byteArray.Length); //写入参数 
                newStream.Close();
                response = (HttpWebResponse)request.GetResponse();
            }
            catch (WebException ex)
            {
                response = (HttpWebResponse)ex.Response;
            }
            StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
            string textResponse = sr.ReadToEnd(); // 返回的数据
            JsonResultInfo deinfo = JsonConvert.DeserializeObject<JsonResultInfo>(textResponse);
            var results = deinfo.Result;
            var message = deinfo.message;
        }

        {
            string url = "http://localhost:8022/ResolveResult/GetTest";
            //封装请求参数  
            Task<string> response = new HttpClient().GetStringAsync(url + "?name=gw");
            string result = response.Result;
            JsonResultInfo deinfo = JsonConvert.DeserializeObject<JsonResultInfo>(result);
            var results = deinfo.Result;
            var message = deinfo.message;
        }
        public async Task<ActionResult> HttpClientPost()
        {

            using (var client = new HttpClient(handler))
            {
                //第一种方式
                var content = new FormUrlEncodedContent(new Dictionary<string, string>()
                {
                    {"name","glw"}
                });
                //第二种方式
                //string jsonData = ReturnJson("name", "glw");
                //var content = new StringContent(jsonData, Encoding.UTF8, "application/json");
                //封装请求参数  
                var response = await client.PostAsync(url, content);
                string result = await response.Content.ReadAsStringAsync();

                JsonResultInfo deinfo = JsonConvert.DeserializeObject<JsonResultInfo>(result);
                var results = deinfo.Result;
                var message = deinfo.message;
                return Content(message);
            }
        }
