Question

i have this problem.

my function is this

$.ajax({
            type: "POST",
            url: "/controller/CreateList",
            contentType: "application/json; charset=utf-8",
            traditional: true,
            data: JSON.stringify(myvar),
            success: function (returnArray) {
            }
.....

in my controller i have this action:

public int[] CreateList(List<ERoleCommission> erolecommission){
        List<int> intList= new List<int>();
        ...//populate the List
        return  intList.ToArray();
}

with debug i see that intList has filled with the right value, so it isn’t a c# error,
after calling this action from controller the debug return to js function and returnArray = “System.Int32[]”, it contains only type.
why?
thanks

Without seeing your controller/action I only guess, but my first guess would be that you forget to JSON-encode the data before you return it as an ActionResult from your action. Try something like this in your action:

public JsonResult YourAction() {
    // ... do stuff
    var yourArrayOfData = CreateList(yourListOfData);
    return Json(yourArrayOfData);
}
