elmah也处理了异常 [英] Does elmah handle caught exceptions as well

问题描述

ELMAH 是否记录了例外情况，即使他们不鼓励应用程序？当异常发生时，我想弹出一条消息，并且仍然记录异常。目前，我一直把所有内容都放在try块中，然后吐出消息，但这样做很繁琐。

Does ELMAH logged exceptions even when they do not bubble up to the application? I'd like to pop up a message when an exception occurs and still log the exception. Currently I've been putting everything in try catch blocks and spitting out messages, but this gets tedious.

推荐答案

ELMAH已被更新支持一个名为信令的新功能。

ELMAH has been updated to support a new feature called Signaling.

这可以让您处理异常，同时仍然将它们记录到ELMAH。

This allows you to handle exceptions how you want, while still logging them to ELMAH.

try
{
    int i = 5;
    int j = 0;
    i = i / j; //Throws exception
}
catch (Exception ex)
{
    MyPersonalHandlingCode(ex);
    ErrorSignal.FromCurrentContext().Raise(ex); //ELMAH Signaling
}

重新抛出异常可能是一个坏的做法，因为它很难跟踪应用程序的流程。使用信号是一种更好的方法，如果您打算以某种方式处理错误，只需要记录它。

Re-throwing exceptions can be a bad practice as it makes it difficult to trace the flow of an application. Using Signaling is a much better approach if you intended to handle the error in some fashion and simply want to document it.
