How to flatten an ExpandoObject returned via JsonResult in asp.net mvc?

by

Using JSON.NET you can call SerializeObject to “flatten” the expando object:

dynamic expando = new ExpandoObject();
expando.name = "John Smith";
expando.age = 30;

var json = JsonConvert.SerializeObject(expando);

Will output: 

{"name":"John Smith","age":30}

In the context of an ASP.NET MVC Controller, the result can be returned using the Content-method:

public class JsonController : Controller
{
    public ActionResult Data()
    {
        dynamic expando = new ExpandoObject();
        expando.name = "John Smith";
        expando.age = 30;

        var json = JsonConvert.SerializeObject(expando);

        return Content(json, "application/json");
    }
}
