You can also System.Web.Script.Serialization; as below

using System.Web.Script.Serialization;

public ActionResult MyAction(string myParam)
{

    return  new JavaScriptSerializer().Serialize(myObject);
}

Ajax 

$.ajax({
    type: 'POST',
    url: '@Url.Action("MyAction","MyMethod")',
    dataType: 'json',
    contentType: "application/json; charset=utf-8",
    data: JSON.stringify({ "myParam": "your data" }),
    success: function(data)
    {
        console.log(data)
    },
    error: function (request, status, error) {

    }
});

If you need to send JSON in response to a GET, you'll need to explicitly allow the behavior by using JsonRequestBehavior.AllowGet.

public JsonResult Foo()
{
    return Json("Secrets", JsonRequestBehavior.AllowGet);
}

Depending on your syntax preferences, the following also works:

public ActionResult MyAction()
{
    return Json(new {Data = myObject});
}

From the controller you can just return a JsonResult:

public ActionResult MyAction()
{
    ... // Populate myObject
    return new JsonResult{ Data = myObject };
}

The form of the Ajax call will depend on which library you're using, of course. Using jQuery it would be something like:

$.getJSON("/controllerName/MyAction", callbackFunction);

where the callbackFunction takes a parameter which is the data from the XHR request.
