Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name extensions to ASP.NET. Note In the example, the mode att

So I simply do this in global.asax: void Application_error(object sender, EventArgs e) { SendMessageToAdministarator(Server.GetLastError().ToString()); } But actually many times Application_Error is called even though the application won't crash. And I wish to send mail to admin ONLY when the application crashed. Also, do I have a simple way to lift the application back on? I'm http://stackoverflow.com/questions/434859/handling-application-error-in-asp-net-apps-global-asax looking for the simplest solution. asp.net share|improve this question edited Nov 14 '11 at 14:57 Jason Plank 2,12242338 asked Jan 12 '09 at 9:06 Hanan 6973927 add a comment| 1 Answer 1 active oldest votes up vote 48 down vote accepted What kind of errors are send when the application is not crashed? You could check the type of exception and don't send emails on the exceptions that don't crash the app (for example a redirect can throw the ThreadAbortException which I manually filter in code): protected void Application_Error(Object sender, EventArgs e) { Exception ex = Server.GetLastError(); if (ex is ThreadAbortException) return; Logger.Error(LoggerType.Global, ex, "Exception"); Response.Redirect("unexpectederror.htm"); } You could add a redirect to an error page with a message for the user that an error has occured and some links to relevant pages in the site. This is for the 'lift the application back on' - I hope this is what you wanted. Also you might look into logging with log4net which can also log errors on the server and send emails on errors. share|improve this answer edited Oct 20 '11 at 15:43 Josh Stodola 54.5k33147204 answered Jan 12 '09 at 9:18 rslite 35.6k43444 Thank you very much.

This article demonstrates a generic error handler in the global.asax which will be implemented for anyapplication error generated by the web application for whicha custom error http://odetocode.com/articles/69.aspx handler has not been written. There are three parts to this error handling routine1.It writes the error message to the event log2.It sends the development team an email with the error details3.It has a ‘pretty’ message on the web page, letting the user know that an error occurred and that the development team has been notified. We are going to use the asp net Application_Error event of the global.asax file. The HttpApplication class in the System.Web namespace implements this Error event handler, so make sure to add a reference to this namespace. We also need to add a reference to the System.Diagnosistics namespace --- protected void Application_Error(Object sender, EventArgs e) { // declare an exeception object and get the original exception Exception exception = asp net application Server.GetLastError().GetBaseException(); // now we are going to be nice to ourselves and format that stack trace. // It would be easy tojust do a string stackTrace = exception.StackTrace, but after// you’ve tried to read a fewof these spending time formatting it – is time well spent string stackEntryDelimiter = " at "; string topStackEntry = String.Empty; string stackTrace = exception.StackTrace; try { int nextStackEntry = stackTrace.IndexOf(stackEntryDelimiter, stackEntryDelimiter.Length); if(nextStackEntry > 0) { topStackEntry = stackTrace.Substring(0, nextStackEntry); } else { topStackEntry = stackTrace; } } catch(Exception ex) { // if for whatever reason our error handler decides to generate an error – well we just eat it Debug.Write(ex.Message); } try {string eventLogFormat = "Error in {0} User: {1} Error Message: {2} Line: {3}";string[] eventLogArgs = { Request.Url.ToString(), Context.User.Identity.Name, exception.Message, topStackEntry }; string eventLogMessage = String.Format(eventLogFormat, eventLogArgs); EventLog objLog = new EventLog(); objLog.Source = "appname"; // change this to the application name for which you’re trapping errors objLog.WriteEntry(eventLogMessage, EventLogEntryType.Error); // write to the event log } catch(Exception ex) { // just eat it Debug.Write(ex.Message); } try { // Again we want t
