Question

Difference between redirectresult and redirecttorouteresult in mvc

Answer 1

RedirectToAction lets you construct a redirect url to a specific action/controller in your application, that is, it'll use the route table to generate the correct URL.

Redirect requires that you provide a full URL to redirect to.

If you have an action Index on controller Home with parameter Id:

You can use RedirectToAction("Index", "Home", new { id = 5 }) which will generate the URL for you based on your route table.

You can use Redirect but must construct the URL yourself, so you pass Redirect("/Home/Index/5") or however your route table works.

You can't redirect to google.com (an external URL) using RedirectToAction, you must use Redirect.

RedirectToAction is meant for doing 302 redirects within your application and gives you an easier way to work with your route table.

Redirect is meant for doing 302 redirects to everything else, specifically external URLs, but you can still redirect within your application, you just have to construct the URLs yourself.
