如何将JSON返回反序列化为从RestSharp调用到API的对象数组？

Question

I am trying to deserialize a JSON return from a RestSharp call to an API.

This is a C# console application. Here is my code so far:

using System;
using RestSharp;
using RestSharp.Authenticators;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json;
using RestSharp.Deserializers;
using System.Collections.Generic;

namespace TwilioTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var client = new RestClient("https://api.twilio.com/2010-04-01");
            var request = new RestRequest("Accounts/{{Account Sid}}/Messages.json", Method.GET);
            request.AddParameter("To", "{{phone number}}");
            request.AddParameter("From", "{{phone number}}");
            client.Authenticator = new HttpBasicAuthenticator("{{account sid}}", "{{auth token}}");
            var response = client.Execute(request);
            var jsonResponse = JsonConvert.DeserializeObject(response.Content);
            Console.WriteLine(jsonResponse);
        }
    }
}

The response is a JSON-formatted list of messages, with keys including "to" , "from" , "body" , and "status" . Here's sort of what that looks like:

{
  "to": "{{phone number}}",
  "from": "{{phone number}}",
  "body": "Sent from your Twilio trial account - Message 1!",
  "status": "delivered"
},
{
  "to": "{{phone number}}",
  "from": "{{phone number}}",
  "body": "Sent from your Twilio trial account - Message 2",
  "status": "delivered"
},

I want to turn that into an array of Message objects, with a Message class that looks like this:

class Message
{
    public string To { get; set; }
    public string From { get; set; }
    public string Body { get; set; }
    public string Status { get; set; }
}

I've been looking around for how to turn JSON into objects and found this page: http://blog.atavisticsoftware.com/2014/02/using-restsharp-to-deserialize-json.html . The third example on the page is along the lines of what I want.

I made some changes to the program and now it looks like this:

    class Program
    {
        static void Main(string[] args)
        {
            // same as above until this point
            ...
            var response = client.Execute(request);
            JsonDeserializer deserial = new JsonDeserializer();
            var messageList = deserial.Deserialize<List<Message>>(response);
            foreach (Message element in messageList)
            {
                Console.WriteLine("To: {0}", element.To);
                Console.WriteLine("From: {0}", element.From);
                Console.WriteLine("Body: {0}", element.Body);

            }
            Console.ReadLine();
        }
    }

However, messageList is empty when I run the program. What am I missing to turn the JSON response into a list of objects? The RestSharp Documentation makes it look fairly straightforward.

I don't know much about RestSharp, but you can get the response content string like that :

var responseContent = client.Execute(request).Content;

And use Json.Net to deserialize your json string :

JObject jsonResponse = (JObject)JsonConvert.DeserializeObject(response.Content);
var messageList = JsonConvert.DeserializeObject<List<Message>>(jsonResponse["messages"].ToString()‌​);
