Post a json object to mvc controller with jquery and ajax

Question

I am trying to submit some values from a form to my mvc controller.

Here is my controller:

 //Post/ Roles/AddUser
    [HttpPost]       
    public Ac         


        

Answer 1

instead of receiving the json string a model binding is better. For example:

[HttpPost]       
public ActionResult AddUser(UserAddModel model)
{
    if (ModelState.IsValid) {
        return Json(new { Response = "Success" });
    }
    return Json(new { Response = "Error" });
}
