How to return a object in HttpResponseMessage in Web api mvc?

Question

In one of my Get request, I want to return an HttpResponseMessage with some content. Currently I have it working as follows:

// GET api/Account/5
[HttpGet]
[ActionName("GetAccount")]
public HttpResponseMessage GetAccount(int id)
{
    Account value;
    try
    {
        var myque = from x in db.Accounts where x.idUser==id select x;
        value= myque.FirstOrDefault();

    }
    catch (Exception)
    {
        return new HttpResponseMessage { Content = new StringContent("[{\"Success\":\"Fail\"},{\"Message\":\"Login Fail\"}]", System.Text.Encoding.UTF8, "application/json") };
    }
    return new HttpResponseMessage { Content = new StringContent("[{\"Success\":\"Success\"},{\"Message\":\"Login successfully\"}],{\"Data\":"+value+"}", System.Text.Encoding.UTF8, "application/json") };
}

I want to add value to HttpResponseMessage. Value will return a json normal.

[
    {
    "Success": "Success"
    },
    {
    "Message": "successfully"
    }
    Value will display at here  
]

Answer 1

Since you are using [ActionName("GetAccount")]... you should use IActionResult as the return type.

Otherwise if you want to use HttpResponseMessage, use -

[Route("api/GetAccount")]

Also, you can construct the output result like

return new HttpResponseMessage { StatusCode = HttpStatusCode.OK, Content = data };

Use Jobject to return

return new JObject(<your dynamic object here>);
