MVC3重载指标的行动得到500错误 [英] MVC3 Overloading the Index action getting 500 errors

问题描述

我有一些问题超载控制器Index操作。在控制器我有以下动作：

I having some problems overloading the Index action in a controller. In the controller I have the following actions:

public ActionResult Index(int id)
{
    return View();
}

public ActionResult Index()
{
    return View();
}

要或者URL（controllername /或controllername / 1），导致500错误。然而，当我使用：

Going to either URL (controllername/ or controllername/1) results in a 500 error. However when I use:

public ActionResult Index(int? id)
{
    return View();
}

该controllername / URL的作品，但controllername / 1的结果在404错误。我的Global.asax是pretty香草：

The controllername/ URL works but controllername/1 results in a 404 error. My global.asax is pretty vanilla:

routes.MapRoute(
    "Default", // Route name
    "{controller}/{action}/{id}", // URL with parameters
    new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);

我想要做的就是能够处理空ID以及值的整数ID。任何建议将不胜AP preciated。

What I would like to do is be able to handle a null id as well as an integer id value. Any suggestions would be greatly appreciated.

谢谢！

推荐答案

我想你会需要明确的是，路线：

I think you will need to explicit the routes for that:

routes.MapRoute(
    "ControllerName", // Route name
    "ControllerName/{id}", // URL with parameters
    new { controller = "ControllerName", action = "Index", id = UrlParameter.Optional }
);

如果它不工作，你可能需要更明确之前补充一点：

if it doesn't work, you may need to be more explicit and add this before:

routes.MapRoute(
    "ControllerName",
    "ControllerName",
    new { controller = "ControllerName", action = "Index"}
);
