Sending n number of parameters in api (aspnet core)

I am trying to call an Web API which is in aspnet core Problem is , the number of parameters are not fixed in this. Parameter can be 2 or 10 ( no of parameters will be between 0 to 15 , a guess ) Below is JS code

$(function () {
            $('#btn').click(function () {
                var src = [
                    {
                        "Question1": "Answer1",
                        "Question2": "Answer2",
                        "Question3": "Answer3",
                        "Question4": "Answer4",
                        "Question5": "Answer5"
                    }
                ];
                $.ajax(
                    {
                        url: 'api/Default/',
                        method: 'POST',
                        dataType: 'JSON',
                        data: JSON.stringify(src),
                        contentType: "application/json",
                        success: function (d) {
                            alert("Success");
                        },
                        error: function (e) {
                            alert("Error please try again");
                        }
                    });
            })
        })

And API 

[Produces("application/json")]
[Route("api/Default/")]
public class DefaultController : Controller
{
    [HttpPost]
    public JsonResult apc(string [][] s)
    {
        string str;
        //Code Here
        return Json(true);
    }
}

I also tried adding a list of class as parameter instead of string array

public class param
{
    public string key { get; set; }

    public string Value { get; set; }
}

But Parameter value is always null. I used the same concept in MVC5 and it works perfectly there but not working in .Net Core How can we send multiple parameter here ??

Because of the dynamic nature of the data to be posted you can use an array of Dictionary

[Produces("application/json")]
[Route("api/Default/")]
public class DefaultController : Controller {
    [HttpPost]
    public JsonResult apc([FromBody]Dictionary<string,string>[] data) {
        var value = data[0]["Question1"]; // Should be "Answer1"
        //Code Here
        return Json(true);
    }
}

Try to send the JSON as string and send it like bellow :

 [HttpPost]
public JsonResult apc(string s)
{
    string str;
    //Code Here
    return Json(true);
}

then handle the json from the .NET side
