asp.net mvc gets the value of the Url parameter in the View

If the url is /home/index?id=3, direct Request is OK.
But if the route is set to: {controller}/{action}/{id}
The url is /home/index/3
How do I get the value of the parameter id in the page view?

After checking the information, many people use Action to obtain the parameter value and use Viewdata to transfer it to View
For example
phonelist in Controlers
public ActionResult phonelist(int id)
  {
  ViewData["id"] = id;
  return View();
  }

Actually, it's not necessary, just get it like this in the view:
<%=Html.ViewContext.RouteData.Values["id"]%>
Even if there is no ID parameter, the error will not be reported.

Similarly: <%=Request.RequestContext.RouteData.Values["id"] %>sum
<%=Html.ViewContext.RouteData.Route.GetRouteData(Html.ViewContext.HttpContext). Values["id"]%>
can also be picked up.

Note: RouteData cannot be directly accessed in the user control, RouteData is a property in the Page object.
So you need to use this. Page.RouteData to get the parameters
Use this. Page.RouteData.Values["id"]to get the value of the parameter
