Web API 2反序列化对象，其中包含Dictionary <string，dynamic =“”>

Question

我有一个接受JObject的Web API2帖子操作。

    [Route("api/Sendemail")]
    public void Post([FromBody]JObject value)
    {
        var personalisation = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(value.First.ToString());
        var recipientEmail = JsonConvert.DeserializeObject<string>(value.GetValue("Email").ToString());
        var templateId = JsonConvert.DeserializeObject<string>(value.GetValue("TemplateId").ToString());

        var response = _client.SendEmail(recipientEmail, templateId, personalisation);
    }

我从我的控制器传入此内容：

    [HttpPost]
    public async Task<IActionResult> Index(FeedbackForm model)
    {
        //Send feedback to address

        var client = new HttpClient();

        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        try
        {
            var personalisation = new Dictionary<string, dynamic>
            {
                {"feedback",model.Feedback},
                {"name",model.Name},
                {"email",model.Email},
                {"response",""},
                {"referrer",model.Referrer}
            };

            var formContent = new FormUrlEncodedContent(new[]
            {
                new KeyValuePair<string, string>("Personalisation", personalisation.ToString()),
                new KeyValuePair<string, string>("Email", "someone@example.com"),
                new KeyValuePair<string, string>("TemplateId", "blah")
            });

            //Sending POST 
            var response = await client.PostAsync("http://localhost/api/sendemail", formContent);

        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }


        return RedirectToAction("Thanks");
    }

请求看起来正确，但我似乎无法正确反序列化，特别是Dictionary对象。正在正确检索Email和TemplateId。

我想我可能必须为帖子请求设一个强类型对象？
