Deserializing Json in Console App

2018-07-03 02:37:37

I am creating a Web API endpoint that will act as a service to retrieve our application configurations, do logging, etc. The problem I am running into is being able to deserialize the Json in the console applications.

Setup

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public DateTime DateOfBirth { get; set; }
}

Web API

[HttpGet]
[Route("Person")]
public IHttpActionResult GetPerson()
{
    Person person = new Person
    {
        FirstName = "Steve",
        LastName = "Rogers",
        DateOfBirth = new DateTime(1920, 7, 4)
    };

    return Ok(JsonConvert.SerializeObject(person));
}

Console Application

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost");

    var response = client.GetAsync("api/Person").Result;
    var data = response.Content.ReadAsStringAsync().Result;
    var person = DeserializeJson<Person>(data);
}

public static T DeserializeJson<T>(string input)
{
    var result = JsonConvert.DeserializeObject(input);
    var result2 = JsonConvert.DeserializeObject(result.ToString());
    return JsonConvert.DeserializeObject<T>(result2.ToString());
}

Values

data = ""{"FirstName":"Steve","LastName":"Rogers","DateOfBirth":"1920-07-04T00:00:00"}""

result = "{"FirstName":"Steve","LastName":"Rogers","DateOfBirth":"1920-07-04T00:00:00"}"

result2 = {{ "FirstName": "Steve", "LastName": "Rogers", "DateOfBirth": "1920-07-04T00:00:00" }}

The issue that I am having is that I cannot deserialize into the Person object until I have deserialized for the 3rd time. The value in result2 is the only one I have been able to successfully deserialize into Person . Is there a more efficient way to accomplish this deserialization? Preferably without having 3 iterations.

I was able to get the following to run successfully (based on this Microsoft article):

Console App:

    static void Main(string[] args)
    {
        RunAsync().Wait();
    }

    static async Task RunAsync()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://localhost:3963/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpResponseMessage response = await client.GetAsync("api/Person");
            Person product = await response.Content.ReadAsAsync<Person>();
        }
    }

Controller:

public class PersonController : ApiController
{
    public Person GetPerson()
    {
        Person person = new Person
        {
            FirstName = "Steve",
            LastName = "Rogers",
            DateOfBirth = new DateTime(1920, 7, 4)
        };
        return person;
    }
}
