Can I convert a JSON string into JsonResult ?

Question

I have some stored JSON strings stored in the DB which I want to return to the client as JsonResult . I know that Json(object) turns an object into JsonResult but what if I already have the result in a string ? can I cast it to JsonResult

Answer 1

You could return the string to the client and then use the $.parseJSON() (jquery) to parse it to an actual json object.

Answer 2

You don't want to return a JsonResult because it's job it to serialize an object into JSON string. You already have the JSON string, so just return it in a ContentResult and specify the correct content type:

string json = //get some json from your DB
return new ContentResult { Content = json, ContentType = "application/json" };

Remember that your MVC action methods should all have ActionResult as a return type, so you can return ContentResult just as easily as JsonResult.
