避免的try / catch地狱在我的网页 [英] Avoiding try/catch hell in my web pages

问题描述

我写一个ASP.NET网站，这对我来说是一个新的框架。我发现，我有我的字面上codebehind的每一个方法的try / catch块。所有这些try / catch块做的是捕获异常，然后弹出一个错误信息给用户。是不是有一些在ASP.NET全局错误处理的？值得注意的是我的错误处理中的控制（ASCX）的页面，我想一个办法简单地让每个ASCX来处理自己的错误，而无须强制所有的错误只是处理单个母版页或重定向...

I am writing an ASP.NET website, which is a new framework for me. I find that I have a try/catch block in literally every method of my codebehind. All these try/catch blocks do is catch the exception and then pop-up an error message to the user. Isn't there some sort of global error handler in ASP.NET? It's worth noting that my error handling is within control (ASCX) pages, and I would like a way to simply get each ASCX to handle its own errors without forcing all error handling just to a single master page or a redirect...

感谢以下建议。我曾尝试Page_Error事件，因为它似乎是一个积极的选择。我跑的测试，我的例外情形现在通过Page_Error事件运行，但事情的倒不工作...我使用'Content.ClearError（）在我Page_Error事件的结束，但是，客户端浏览器仍与未处理的结束PageRequestManagerServerErrorException。任何建议？如果有帮助，我使用Telerik的，并试图弹出一个开放的，只要radalert发生错误...

Thanks for advice below. I did try Page_Error as it seems a positive option. I ran a test and my exceptions do now run through Page_Error, however thing's ain't quite working... I use 'Content.ClearError()' at the end of my Page_Error, however, the client browser still ends up with an unhandled PageRequestManagerServerErrorException. Any advice? If it helps, I am using Telerik and trying to pop open a radalert whenever an error occurs...

推荐答案

您可以实现在页级的 Page_Error事件事件处理程序。这听起来像是一个完美的适合你的要求。

You could implement the Page_Error Event handler at the page level. That sounds like the perfect fit for what you asked.

另外，更在全球范围的应用程序级，您可以尝试的Application_Error 事件处理在Global.asax中。

Otherwise, more globally on the application level, you may try the Application_Error Event Handler in Global.asax.
