问题 When specifying asp-controller and asp-action on a link, what's the syntax for also passing an id attribute? E.g. If I wanted to link to the edit URL for a given object, the required URL would be /user/edit/5 for example. Is there a method to achieve this using TagHelpers, or do we still have to fall back to @Html.ActionLink() ? 回答1: You can use the attribute prefix asp-route- to prefix your route variable names. Example: <a asp-action="Edit" asp-route-id="10" asp-route-foo="bar">Edit</a> 回答2

In previous version of Asp MVC it could be done like this: Request.Browser.IsMobileDevice The problem is that the namespace System.Web is not used by Asp.Net 5 . The Request variable in the controller actions is now of type Microsoft.AspNet.Http.HttpRequest , the old version was of type System.Web.HttpRequestBase. Microsoft.AspNet.Http.HttpRequest does not contain the Browser property. I tried looking through
