How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 This code example shows how to create an error handler in the Global.asax file that will catch all unhandled ASP.NET https://msdn.microsoft.com/en-us/library/24395wz3.aspx errors while processing a request — in other words, all the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site. C#VB Copy void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs // Get the exception object. Exception exc = Server.GetLastError(); // Handle HTTP errors if (exc.GetType() == typeof(HttpException)) { // The Complete Error Handling Example generates // some errors using URLs with "NoCatch" in them; // ignore these here to simulate what would happen // if a global.asax handler were not implemented. if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength")) return; //Redirect HTTP errors to HttpError page Server.Transfer("HttpErrorPage.aspx"); } // F

How do I, through minimal effort, catch all unhandled exceptions? this question seems to say it's impossible, but that doesn't make sense to me (and it's about .NET 1.1 in windows apps): c# asp.net share|improve this question edited Jul 29 '09 at 6:03 unhandled exception error Corey Ross 1,29311012 asked Nov 17 '08 at 14:49 adambox 8,02662332 3 Isn't that treating the symptoms, and not the cause? i.e. shouldn't you be looking at the cause of the SQL timeouts by running a SQL Profiler trace on the database server? –Mitch Wheat Nov 17 '08 at 14:58 1 I think you need to clarify what you mean by "catch": As in try..catch where you can handle the exception, or if you merely want to be informed an unhandled exception occurred, and log where/when (e.g. ELMAH) –Robert Paulson Jul 29 '09 at 6:05 add a comment| 13 Answers 13 active oldest votes up vote 24 down vote All unhandled exceptions finally passed through Application_Error in global.asax. So, to give general exception message or do logging operations, see Application_Error. share|improve this answer edited Nov 17 '08 at 15:01 answered Nov 17 '08 at 14:54 Ali Ersöz 9,49184055 10 look into the the first sentence; "I have a website built in C#.NET that tends..." –Ali Ersöz Nov 17 '08 at 22:03 1 To anyone trying to figure out what the previous comment is saying - I assume it's answering a now deleted comment.
