Action Result

public class MovieController : Controller
{
	// GET: Movies/Random
	public ActionResult Random()
	{
		var movie = new Movie() { Name = "Shrek!" };
		return View(movie);
		// return new EmptyResult();
	}
}

ActionResult is the base class for all types of results that can be returned from an Controller
EmptyResult does not have an helper class

Redirects do not support POST Verb so data can only be sent in the URL

public class MovieController : Controller
{
	// GET: Movies/Random
	public ActionResult Random()
	{
		var movie = new Movie() { Name = "Shrek!" };
		// Controller Name, Action Name
		return new RedirectToRouteResult("Index", "Home", new {
			name = "David", age = 1
		})
	}
}

Action Arguments

If an Action Method takes an parameter then MVC framework looks for request data with the same parameter
This parameter can be in the URL, Query String or Embedded in request from Form

To make parameter optional we should mark them as Nullable

public ActionResult Index(int? pageIndex, string? sortBy)
{
	if (!pageIndex.HasValue)
		pageIndex = 1;
 
	if (string.IsNullOrWhiteSpace(sortBy))
		sortBy = "Name";
 
	return Content($"pageIndex={pageIndex}&sortBy={sortBy}");
}

Attribute Routing

Attribute Routing allows us to specify an Custom Route for an Action
Routing Constrains With Attribute Routing in MVC 5.0

[HttpGet]
[Route("Movies/Released/{year}/{month:regex(\\d{2}):range(1, 12)}")]
public ActionResult ByReleaseDate(int year, int month)
{
	return Content($"{year}/{month}");
}
