How to Get Exception StackTrace in Application_Error ?

[Cramer]

I'm developing a new ASP.NET 3.5 app and I have an http module hooked up to
Application_Err or that logs [otherwise unhandled] detailed exception data.

When it parses and evaluates unhandled exceptions, it "sees" all exceptions
as type "System.Web.Htt pUnhandledExcep tion", with the message:
"Exception of type 'System.Web.Htt pUnhandledExcep tion' was thrown."

At the same time and for the exact same exception, on my development
computer, ASP.NET shows a very informative error message, with the text,
"Server Error in '/MyAppNameHere' Application" -- and that is followed by
the specific exception message (e.g., "Divide by zero error
encountered.") -- and that is followed by the specific line that choked,
incliding the .cs source code line number and .cs file path -- followed by
the stack trace that shows the actual sequence of method calls that lead to
the method that threw the exception.

My question:
In my http module hooked up to Application_Err or, how can I get the same
detailed information that ASP.NET places into the informative "error message
page", rather than simply getting the HttpUnhandledEx ception exception?

Thanks.

Hi Cramer,

Are you looking for System.Diagnost ics.StackFrame?

http://msdn.microsoft.com/en-us/library/system.diagnostics.stackframe.aspx

This should let you look at the kind of information you've specified in your
question. Please note, though, that using StackFrame can seriously slow
down your application, so use it if you really, really, really, really,
really need to.

I don't know what your HttpModule does or how it works. But if you want to
get the "real" exception in Application_Err or, it would be:

Exception ex =
Server.GetLastE rror().GetBaseE xception();
