Hello I want to return an anchor from Mvc Controller

Controller name= DefaultController;

public ActionResult MyAction(int id)
{
        return RedirectToAction("Index", "region")
}

So that the url when directed to index is 

http://localhost/Default/#region

So that 

<a href=#region>the content should be focus here</a>

I am not asking if you can do it like this: How can I add an anchor tag to my URL?

I found this way:

public ActionResult MyAction(int id)
{
    return new RedirectResult(Url.Action("Index") + "#region");
}

You can also use this verbose way:

var url = UrlHelper.GenerateUrl(
    null,
    "Index",
    "DefaultController",
    null,
    null,
    "region",
    null,
    null,
    Url.RequestContext,
    false
);
return Redirect(url);

    You are a genious mate! Here what I ended doing: return new RedirectResult(Url.Action("Index",new{ PKMvrEmployeeId = MvrId }) + "#region"); – hidden May 21 '12 at 21:32

    +1 for using RedirectResult instead of calling Redirect(..) method. In MVC under release and IIS6 you can end up with exceptions caused by redirecting because a request is perhaps already redirected, or part of a child action, or content is already sent. – Jaans Aug 08 '13 at 02:55

    In MVC 5, when using RedirectToAction it appears to escape the # to a %23. Is no one else experiencing this? – jakejgordon Oct 20 '17 at 01:04
  • For me, it's going back up again when I use the same method. – Zeeshan Ahmad Khalil May 05 '20 at 16:10

Great answer gdoron. Here's another way that I use (just to add to the available solutions here).

return Redirect(String.Format("{0}#{1}", Url.RouteUrl(new { controller = "MyController", action = "Index" }), "anchor_hash");

Obviously, with gdoron's answer this could be made a cleaner with the following in this simple case;

return new RedirectResult(Url.Action("Index") + "#anchor_hash");

A simple way in dot net core

public IActionResult MyAction(int id)
{
    return RedirectToAction("Index", "default", "region");
}

The above yields /default/index#region. The 3rd parameter is fragment which it adds after a #.

To Expand on Squall's answer: Using string interpolation makes for cleaner code. It also works for actions on different controllers.

return Redirect($"{Url.RouteUrl(new { controller = "MyController", action = "Index" })}#anchor");
