的HandleError属性没有任何影响 [英] HandleError attribute doesn't have any effect

问题描述

在我的web.config我已经包括：

In my web.config I have included:

<customErrors mode="On" />

现在死亡的黄色屏幕不​​再显示。
我想我必须包含的HandleError属性我控制器方法或类本身：

Now the yellow screen of death isn't shown anymore. I thought I'd have to include the HandleError attribute to my controller methods or the class itself:

[HandleError]
public ActionResult About()
{
    throw new Exception("Just an exception");
    return View();
}

但它没有任何效果，这是一样的：

But it doesn't have any effect, it's the same as:

public ActionResult About()
{
    throw new Exception("Just an exception");
    return View();
}

在这两种情况下显示自定义错误页。那么什么是对的HandleError属性？

In both cases the custom error page is shown. So what is it about the HandleError attribute?

推荐答案

这可能发生，如果FilterConfig.cs的MVC项目App_Start文件夹下，包含：

That can happen if FilterConfig.cs, under App_Start folder of the MVC project, contains:

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

由于过滤器的HandleError注册的应用程序启动时，你不必装饰与此属性的每个控制器动作。

Since the HandleError filter is registered when the App starts, you don't have to decorate each controller action with this attribute.
