Mvc4 Querystring参数不起作用

Question

In Asp.net MVC4 I have created below URL showing 404 error with IIS8.0

http://{ParentURL}/Areas/Admin/Menu/Index?actoin=Add

Please help me on it.

Answer 1

You URL http://{ParentURL}/Areas/Admin/Menu/Index?mode=Add goes to:

Area: Admin

Controller: Menu

Action + View: Index

Parameter: mode

So in MenuController.cs (under Admin area) you should have this:

public ActionResult Index(string mode)
{
   //code
   return View();
}

UPDATE:

Change your URL to: http://{ParentURL}/Admin/Menu/Index?mode=Add

The parameters of your Action must have the same name as in your route declaration. Also another mistake is to use Areas in your URL, you can remove it or change your default route.

Controller:

public ActionResult Index(string mode)
{
   return View(ViewMenuModel);
}

View:

var JsSuccessAction = '@Url.Content("~/Admin/Menu/Index?mode=Add")';

Route:

public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute( "Admin_default", "Admin/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } );
}

Answer 2

You need to set a route in route config :

context.MapRoute(
    "Areas",
    "Areas/{controller}/{action}/{id}",
    new { action = "Index", id = UrlParameter.Optional }
);

add this to your root config and try .. will work
