ASP .Net Core Call Controller Function from Javascript with redirect from Controller

Question

I am breaking my head on this and cant find a solution. In short I have a ASP .Net Core MVC page that has a Javascript list. I need to pass that list to a redirect. I have this in place and it is working so not the solution I am looking for as it is not secure.

So what I am trying to do is calling the Controller function from Javascript passing the list. I can only do this with Ajax but the controller wont redirect on an Ajax call. Is there anyone that has encountered a similar problem and possibly a solution for this?

Javascript var -> Controller -> redirect.

Thank you in advance guys

Is it possible for you to make a redirect on ajax call return (for example, by using Jquery ajax success setting you can implement some code at the return of a call really easily), or do you absolutely have to redirect with C# ? — Error 404 Brain not found

I kind of need to redirect from C# as I ned to pass a model to the page that is generated based on the list that was sent from the initial javascript list. I have started looking at the following but not much luck eg: window.location.href = '@Url.Action("Index", "Sandbox")' + list; — Martin

I have searched for: asp net core window location href with parameters asp.net mvc best results but not working as expected — Martin

window.location.href ="Sandbox/Index?test=" + 'My test string' This code sends a single string as expected. I want to send a list. So a dirty solution would be to add list items to string and coma delimit. But is that the best solution? — Martin

I found the solution. So leaving the answer here for any future guys having the same problem.

Javascript

    $("#btn").click(function () {
       var PostData = ["1","2","3","4","5","6","7","8","9"]
       if (PostData != "") {            
          window.location.href ="Controller/Function?test=" + PostData
                   
       } else
         alert('Oops.!!');});

C# Controller

 public IActionResult Test(string test)
    {
        return RedirectToAction("function", "Controller", new { test });
    }
