Page Level Error Handling In Asp.net Example
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 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(Ht

I have viewed the question Good error handling practice and it doesn't really say too much about this. My experience has been excluding some very specific circumstances (such as transactions) most of the ASP.NET applications we are writing are along the lines of void ButtonEventHandler(object sender, EventArgs e) { Page.Validate(); if (Page.IsValid) { //Do a database insert or update thru relevant datalayers. //If its a transaction then we rollback internally and rethrow //the handling in asp exception. } } Why not just have a global exception handler? Usually (at this point) the only thing I can do is abort the operation gracefully and tell the user to try again. c# asp.net error-handling share|improve this question asked Oct 24 '11 at 12:55 Maxim Gershkovich 12.6k2791182 stackoverflow.com/questions/155203/good-error-handling-practice –ChrisBint Oct 24 '11 at 13:02 At the same point, I usually catch known possible exceptions and display a message to the user, leaving unexpected exceptions for global handling. You could catch all exceptions (most people argue against this) and display a message as long as you've logged the exception. If you don't log the exception, it will be a huge pain to track down the error. You may spend weeks trying to reproduce an error caused by a rare database/services hiccup. –Jim Schubert Oct 24 '11 at 13:06 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted The global place to handle uncatched Exceptions would be in Global.asax by handling Application_Error. As John pointed out, you should always handle exceptions as close as possible to where they might occur and react appropriately. share|improve this answer answered Oct 24 '11 at 13:26 Icarus 45.4k85385 But hold on, my point is this....

In asp.net, one can define one in global.asax, and in windows applications /services, one can define as below AppDomain currentDomain = AppDomain.CurrentDomain; currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyExceptionHandler); But how can I define a global exception handler for a console application ? currentDomain seems not to work (.NET 2.0) ? Edit: Argh, stupid mistake. In VB.NET, one needs to add the "AddHandler" keyword in front of currentDomain, or else one doesn't see the UnhandledException event in IntelliSense... That's because the VB.NET and C# compilers treat event handling differently. c# .net vb.net console console-application share|improve this question edited Jan 30 '14 at 17:09 asked Jun 28 '10 at 14:25 Stefan Steiger 26.2k38185286 add a comment| 4 Answers 4 active oldest votes up vote 174 down vote accepted No, that's the correct way to do it. This worked exactly as it should, something you can work from perhaps: using System; class Program { static void Main(string[] args) { System.AppDomain.CurrentDomain.UnhandledException += UnhandledExceptionTrapper; throw new Exception("Kaboom"); } static void UnhandledExceptionTrapper(object sender, UnhandledExc
