Convert List to JSon and return it in Web API action

Question

I have the following:

var data = new List<DataModel>();

Where DataModel is the following:

public class DataModel {
  public DateTime Date { get; set; }
  public Int32 Users { get; set; }
}

How turn this List into a JSON forma and return it in a WebAPI 2.0 action?

Thank you, Miguel

You can do it the magic way...

  public class JsonListObjectController : ApiController
  {
      public List<DataModel> Get()
      {
          var data = new List<DataModel>()
        {
            new DataModel() {Date = DateTime.Today, Users = 100},
            new DataModel() {Date = DateTime.Today, Users = 120}
        };

          return data;
      }

  }

or you can do it the "I want to stay in control way"

    public HttpResponseMessage Get()
    {
        var data = new List<DataModel>()
        {
            new DataModel() {Date = DateTime.Today, Users = 100},
            new DataModel() {Date = DateTime.Today, Users = 120}
        };

        return new HttpResponseMessage()
            {
                Content = new StringContent(JArray.FromObject(data).ToString(), Encoding.UTF8, "application/json")
            };
    }
