我是用我的Global.asax文件中ELMAH记录的事件给用户时未处理的异常发生时转移到一个反馈表。

I am using the Elmah Logged event in my Global.asax file to transfer users to a feedback form when an unhandled exception occurs.

有时候我登录其他处理的异常。例如：

Sometimes I log other handled exceptions. For example:

ErrorSignal.FromCurrentContext().Raise(new System.ApplicationException("Program code not found: " + Student.MostRecentApplication.ProgramCode));

// more code that should execute after logging this exception

我遇到的问题是，记录的事件被炒鱿鱼为未处理而这些处理，产生的异常。有没有一种方法来确定，在记录的事件处理程序，通过ErrorSignal类的异常是否提高或只是未处理？是否有其他ELMAH事件，我可以利用？

The problem I am having is that the Logged event gets fired for both unhandled and these handled, raised exceptions. Is there a way to determine, in the Logged event handler, whether the exception was raised via ErrorSignal class or was simply unhandled? Are there other Elmah events that I can take advantage of?

推荐答案

厌倦了试图找到正确的方式做到这一点，所以我结束了创建我自己的异常类型：

Tired of trying to find the "right" way to do this, so I ended up creating my own exception type:

public class HandledElmahException : Exception
{
    public HandledElmahException() : base() { }
    public HandledElmahException(string message) : base(message) { }
    public HandledElmahException(string message, Exception innerException) : base(message, innerException) { }
}

然后，在ErrorLog.Logged事件处理我只是检查，看看是否异常的类型是 HandledElmahException 。

void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args)
{
    if (args.Entry.Error.Exception is HandledElmahException)
        return;

    // my code to transfer to custom error page to collect feedback...

}

所以，如果我不想带他们去的errorPage，当记录一个例外，我用我特殊的 HandledElmahException 类的一个实例，它可以是来自

So, if I don't want to take them to the ErrorPage, when an exception is logged, I use an instance of my special HandledElmahException class, which can be derived from.

ErrorSignal.FromCurrentContext().Raise(new HandledElmahException("Program code not found: " + Student.MostRecentApplication.ProgramCode));
