如何在Url.Action中传递一些参数？

Question

Url.Action("CreatePerson", "Person", new { id = 6, name = "rachel", grade="a" });

When I get the parameters in the action, I get only the first value (value of id ), but I don't get the values of name and grade . Why?

Answer 1

You need to define the additional parameters on the controller method like so:

 public ActionResult SuccessfulPostData(int id, string name, string grade)
        {

            ViewBag.name= name;
            return View();
        }

In the View you can display the value:

 @Viewbag.name

Also sometimes you need to explicitly define route parameters. This is found in the RouteConfig.cs file.

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}/{name}/{grade}",
        defaults: new { controller = "Home", action = "SuccessfulPostData", id = UrlParameter.Optional, name = UrlParameter.Optional, grade = UrlParameter.Optional }
    );
