在我的一个Get请求中，我想返回一个包含一些内容的HttpResponseMessage。

// 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") };
}

我想将值添加到HttpResponseMessage。值将返回一个json正常值。

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