Should my MVC controller really know about JSON?

Question

The JsonResult class is a very useful way to return Json as an action to the client via AJAX.

public JsonResult JoinMailingList(string txtEmail)
{
        // ...

Alternatively, if you don't want to get into using reflection, you can create a RouteValueDictionary with the result's Data property. Going with the OP's data...

var jsonData = new RouteValueDictionary(result.Data);
Assert.IsNotNull(jsonData);

Assert.AreEqual(2,
                jsonData.Keys.Count);

Assert.AreEqual("123",
                jsonData["foo"]);

Assert.AreEqual(true,
                jsonData["success"]);
