ASP.NET MVC 4错误处理

Question

好的,所以我试图让我的控制器在错误Error.cshtml的Shared文件夹下去.我在启动时配置了过滤器:

Global.asax中

protected void Application_Start()
{
    ...
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    ...
}

FilterConfig.cs

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new HandleErrorAttribute());
}

HomeController.cs

[HandleError(View = "Error")] <---- I have the HandleError attribute
public class HomeController : Controller
{
    IDbConnection _connection = new SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);

    [Authorize]
    public ActionResult Index()
    {
        // get the users current events
        try
        {
            ViewBag.UserEvents = _connection.Query<MyEvents>("select ...)", new { });
        }
        catch (Exception ex)
        {
            throw new HttpException(500, ex.Message);
        }

        return View();
    }
    ...
}

因此,当该Index方法抛出异常因为我没有打开连接时,它只是给了我默认的ASP.NET异常页面.我在这里想念的是什么？

谢谢!

您是否有机会在本地计算机上运行此操作？如果将customErrors设置为Off或RemoteOnly,则默认情况下HandleError不会在本地计算机上显示错误.将其设置为开.
