How can I use Url.Action() in a class file of MVC project?

Like:

namespace _3harf
{
    public class myFunction
    {
        public static void CheckUserAdminPanelPermissionToAccess()
        {
            if (ReferenceEquals(HttpContext.Current.Session["Loged"], "true") &&
                myFunction.GetPermission.AdminPermissionToLoginAdminPanel(
                    Convert.ToInt32(HttpContext.Current.Session["UID"])))
            {
                HttpContext.Current.Response.Redirect(Url.Action("MainPage", "Index"));
            }
        }
    }
}

@Simon Belanger's answer is perfectly working, but UrlHelper.Action() generates relative URLs and in my case i need the fully qualified absolute URL. So what i need to do is - i have to use one of the overload provided by UrlHelper.Action() method.

var requestContext = HttpContext.Current.Request.RequestContext;
string link = new UrlHelper(requestContext).Action("Index", "Home", null, HttpContext.Current.Request.Url.Scheme);

So let say if your application hosted on "https://myexamplesite.com" then above code will give you full url like this - "https://myexamplesite.com/Home/Index". Hope this answer will help those readers who will come across this link.

For those arriving late to this post, using .Net Core and .Net 5.0, You should try this;

private readonly IUrlHelperFactory _urlHelperFactory;
private readonly IActionContextAccessor _actionContextAccessor;

 public EmailSenderService(IUrlHelperFactory urlHelperFactory,
            IActionContextAccessor actionContextAccessor)
        {
            _urlHelperFactory = urlHelperFactory;
            _actionContextAccessor = actionContextAccessor;
        }

 private string GenerateUrl(string action, string controller, object routeValues = null)
        {
            var urlHelper = _urlHelperFactory.GetUrlHelper(_actionContextAccessor.ActionContext);
            return urlHelper.Action(action, controller, routeValues, _actionContextAccessor.ActionContext.HttpContext.Request.Scheme);
        }

I tried to use @simion's answer and I was getting an invalid type in the constructor for UrlHelper. "cannot convert from System.Web.Routing.RequestContext to System.Net.Http.HttpRequestMessage"

So I used this

var urlHelper = new System.Web.Mvc.UrlHelper(HttpContext.Current.Request.RequestContext); string url = urlHelper.Action("MainPage", "Index");

worked out for me.

You can also use this

return RedirectToAction("Index", "MainPage");

You simply need to pass Url property from your controller to your class file,

string CreateRoutingUrl(IUrlHelper url)
{
    return url.Action("Action", "Controller");
}

and on your controller :

MyClass.CreateRoutingUrl(Url);
