Asp.net Web Api 2 - how to get access_token from C# code

I am preparing a C# Api for my website. When I call the following code to login and get the access token, response.IsSuccessStatusCode is ok (200), but I could not find any access_token from the response. I assume the access token comes through response body, but could not find a proper function to get the response body.

var token = new Dictionary<string, string> { {"grant_type", "password"}, {"username", "[email protected]"}, 
{"password", "OOKKUUc564$"},};

var tknModel = new FormUrlEncodedContent(token);

var resp = await client.PostAsync("http://parkatstreet.com/Token", tknModel);
if (response.IsSuccessStatusCode)
{
    string responseStream = response.Headers.ToString();
}

The response I am getting is:

{StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Pragma: no-cache

And the response I expect is:

You can create a new Console Application and use the following code:

namespace APIClientConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            RunAsync().Wait();
        }

        static async Task RunAsync()
        {
            using (var client = new HttpClient())
            {
                // TODO - Send HTTP requests              
                client.BaseAddress = new Uri("http://localhost:24780/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));                
                // HTTP POST                
                var body = new List<KeyValuePair<string, string>>
                {
                    new KeyValuePair<string, string>("grant_type", "password"),
                    new KeyValuePair<string, string>("username", "bnk"),
                    new KeyValuePair<string, string>("password", "bnk123")                    
                };
                var content = new FormUrlEncodedContent(body);
                HttpResponseMessage response = await client.PostAsync("token", content);
                if (response.IsSuccessStatusCode)
                {
                    string responseStream = await response.Content.ReadAsStringAsync();
                    Console.WriteLine(responseStream);   
                    Console.ReadLine();                 
                }
            }
        }
    }        
}

In your comment you use javascript to access to response content (or body as you call it)

$.post(url, data).success(saveAccessToken).always(showResponse);

In C# you access can get the content with

string responseStream = await response.Content.ReadAsStringAsync();

If you have Microsoft.AspNet.WebApi.Client referenced you can parse the content with

ResponseType result = await response.Content.ReadAsAsync<ResponseType>();
