jQuery getJSON with .NET MVC not working

I have setup a getJSON call when page loads in my .NET MVC app like this:

$(document).ready(function(){
   $.getJSON("/Administrator/GetAllUsers", function (res) {

            // getting internal server error here...
        });

});

And the action looks like this:

  [HttpGet]
    [ActionName("GetAllUsers")]
    public string GetAllUsers()
    {
        return new JavaScriptSerializer().Serialize(ctx.zsp_select_allusers().ToList());
    }

I'm getting this error:

500 (Internal Server Error)

What am I doing wrong here???

try it 

$.getJSON('@Url.Action("GetAllUsers", "Administrator")', function (res)   {

            alert(res);
        });

 [HttpGet]
    public ActionResult GetAllUsers( ) {

          //get the data from db , then send it
          //i'm passing dummy text 'got it'

        return Json("got it", JsonRequestBehavior.AllowGet);
    }

Change your return type in method and return Json, like bellow,

[HttpGet]
[ActionName("GetAllUsers")]
public ActionResult GetAllUsers()
{
    var data = ctx.zsp_select_allusers().ToList();
    return Json(data, JsonRequestBehavior.AllowGet);
}

As you have mentioned in your comment, you are still getting 500 error. I think this controller have [Authorize] attribute and you are calling this method without login. In this case you can use [AllowAnonymous] attribute in GetAllUsers() to access the method.

In MVC, json result only returned if you make post request to it for some security purposes, until and unless you explicitly specify JsonRequestBehavior.AllowGet, also change your return type

[HttpGet]
    [ActionName("GetAllUsers")]
    public JsonResult GetAllUsers()
    {
        return Json(ctx.zsp_select_allusers(), JsonRequestBehavior.AllowGet);
    }
