如果Content-Type为“ text / plain”，则GET RestSharp请求返回空值，而如果Content-Type为“ application / json”，则返回数据

Question

I've started to learn some MVC, and am looking at creating a dashboard using a Restful API. So far, everything is going fairly well, however, I've come across what I imagine is a very simple fix which I can't seem to figure out.

If I make a GET request to part of the API which has a application/json as the response body, then everything works fine. If, however, the response body returns a text/plain value, then all I receive is a null value.

When I access the API URL in a web browser or Postman it simply returns a number, so this shouldn't be a complex issue, I'm just missing something obvious because of my lack of knowledge.

How can I return the data of an API using text/plain?

This is the code that I am using within my Controller:

   var client = new RestClient("http://URL:1234/api/");
            client.Authenticator = new HttpBasicAuthenticator("XXXXX", "XXXXX");
            var ErrorQueue = new RestRequest("errorqueue/count", Method.GET);
            ErrorQueue.AddHeader("Accept", "text/plain");
            ViewBag.errorQueueTotal = client.Execute<DashboardModel>(ErrorQueue).Data;

This is the code within my Model:

public class DashboardModel
{

    public DataModel data { get; set; }

}

public class DataModel
{
    public string version { get; set; }
    public string name { get; set; }
    public string uptime { get; set; }
    public int errors { get; set; }
}

And just for reference, here is my view which is calling the ViewBag:

 <div class="container">
    <h3>Error Queue</h3>
    <div class="panel panel-default panel-default-Messages">
        <div class="panel-body">
            <label>Error Queue: </label>
            <span id="errorSpanID">@ViewBag.errorQueueTotal.data.errors</span>
        </div>
    </div>
</div>

I believe that the issue lies with how I'm trying to return the data once the API has been requested, but some clarification on where I'm going wrong would be really helpful.

Quick thanks to Fran for taking the time to comment and assist.

The code below is what I have used to resolve the issue. I'm not totally sure why RestSharp was returning a null value, when it worked for all the other GET requests I've made. None the less, this works perfectly for me! :)

var clienttest = new WebClient();
            clienttest.Credentials = new NetworkCredential("XXXXX", "XXXXX");
            var response = clienttest.DownloadString("http://XXXXX:1234/api/Test/1234/state");
            ViewBag.details = response.ToString();
