How to add link parameter to asp tag helpers in AS

问题:

I have a lot of experience with ASP.NET MVC 1-5. Now I learn ASP.NET Core MVC and have to pass a parameter to link in page. For example I have the following Action

 [HttpGet]
 public ActionResult GetProduct(string id)
 {
      ViewBag.CaseId = id;
      return View();
 }

How can I implement the link for this action using tag helpers?

<a asp-controller="Product" asp-action="GetProduct">ProductName</a>

You can use the attribute prefix asp-route- to prefix your route variable names.

Example:

<a asp-controller="Product" asp-action="GetProduct" asp-route-id="10"> ProductName</a>
