Redirect to a hash from the controller using "RedirectToAction"
提问by hidden
Hello I want to return an anchor from Mvc Controller
你好，我想从 Mvc 控制器返回一个锚点
Controller name= DefaultController;
控制器名称= DefaultController;
public ActionResult MyAction(int id)
{
return RedirectToAction("Index", "region")
}
So that the url when directed to index is
这样当指向索引时的 url 是
http://localhost/Default/#region
So that
以便
<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?
我不是在问您是否可以这样做：如何将锚标记添加到我的 URL？

I found this way:
我找到了这种方式：
public ActionResult MyAction(int id)
{
return new RedirectResult(Url.Action("Index") + "#region");
}
You can also use this verbose way:
您还可以使用这种详细的方式：
var url = UrlHelper.GenerateUrl(
null,
"Index",
"DefaultController",
null,
null,
"region",
null,
null,
Url.RequestContext,
false
);
return Redirect(url);

Great answer gdoron. Here's another way that I use (just to add to the available solutions here).
很好的答案 这是我使用的另一种方式（只是为了添加到此处的可用解决方案中）。
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;
显然，在 gdoron 的回答下，在这个简单的情况下，可以使用以下内容进行清洁；
return new RedirectResult(Url.Action("Index") + "#anchor_hash");

A simple way in dot net core
dot net core中的一个简单方法
public IActionResult MyAction(int id)
{
return RedirectToAction("Index", "default", "region");
}
The above yields /default/index#region. The 3rd parameter is fragmentwhich it adds after a #.
以上产生/default/index#region。第三个参数是它在# 之后添加的片段。

To Expand on Squall's answer: Using string interpolation makes for cleaner code. It also works for actions on different controllers.
扩展 Squall 的答案：使用字符串插值可以使代码更简洁。它也适用于不同控制器上的操作。
return Redirect($"{Url.RouteUrl(new { controller = "MyController", action = "Index" })}#anchor");
