Converting int output to JSON

I have created an ASP.NET Web API which finds the sum of two integers using an addition function from a dll file. When i run the application (http://localhost:52241/api/dlladdition/9/6) i get results as "15". The result i want is something like { "result" : 15} (JSON format). How do i achieve that? The JSON codes that i have included in my codes does not seem to work.

Here are my codes:

Addition.cs

using ClassLibraryDll;
public class Addition
{
    static int num1;
    static int num2;
    int sum = MathClass.Add(num1, num2);
}

DllAdditionController.cs

public class Temp
{
    public int num1 { get; set; }
    public int num2 { get; set; }
    public int sum { get; set; }
}

public class DllAdditionController : ApiController
{
    private Addition addition = new Addition();

    public int GET(int num1, int num2)
    {
        int result = ClassLibraryDll.MathClass.Add(num1, num2);
        string json = JsonConvert.SerializeObject(result);
        return (json);
    }
}

Someone please help me. Thank you so much in advance.

my project manager insists for it to be in JSON format :/

It is valid JSON. Your project manager needs to read up on the current JSON specs.

If you want your result wrapped in an object with a result property, you are free to define a class with a single property result and return this class instead.

You can set the response to by JSON by using the JSON Media-Type Formatter

var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.UseDataContractJsonSerializer = true;

If you like to restrict your Web API response to either JSON or XML only, you can call this from your Application_Start method, defined in Global.asax. 

void ConfigureApi(HttpConfiguration config)
{
    // Remove the JSON formatter
    config.Formatters.Remove(config.Formatters.JsonFormatter);

    // or

   // Remove the XML formatter
   config.Formatters.Remove(config.Formatters.XmlFormatter);
}

You may refer to https://learn.microsoft.com/en-us/aspnet/web-api/overview/formats-and-model-binding/json-and-xml-serialization#removing-the-json-or-xml-formatter for more information.
