我想实现错误使用Action过滤器属性的处理按照ScottGu的的博客
I am trying to implement Error handling using Action Filters Attributes as per ScottGu's blog
我的code是如下:
[HandleError] [HandleError(ExceptionType = typeof(NullReferenceException), View = "CustomError")] public class ArticlesController : Controller { public object OhDearACrash() { throw new Exception("Oh Dear"); } public object NullRefCrash() { throw new NullReferenceException(); }我遇到了在那里我从来没有能够作为我收到一个异常时,抛出异常击中CustomError查看问题
I am encountering an issue where I am never able to hit the CustomError view as I receive an exception when the exception is thrown
OhDearACrash:异常是由用户code
OhDearACrash: Exception was unhandled by user code
NullRefCrash:NullReferenceException异常是由用户code
NullRefCrash: NullReferenceException was unhandled by user code
等未处理的异常是由默认拿起[的HandleError]查看哪些路由/共享/ Error.aspx它处理错误。
and so the unhandled exception is picked up by the Default [HandleError] which routes to View/Shared/Error.aspx which handles the error.
我如何处理未处理的异常?
How do I handle the unhandled exception?
推荐答案动作过滤器逐一执行。在你的情况,问题很可能是通用的HandleError行为过滤器是具体的人之前执行。
The action filters are executed one by one. In your case, the problem is probably that the generic HandleError action filter is executed before the specific one.
您可以通过设置过滤器作用的秩序属性影响执行的顺序:
You can influence the order of execution by setting the 'Order' property of your action filter:
[HandleError(Order = 2)] [HandleError(Order = 1, ExceptionType = typeof(NullReferenceException), View = "CustomError")] public class ArticlesController : Controller { }更多推荐
