Complete Example for Error application_error mvc Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config 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 no

No idea why it's been downvoted. :-( perhaps people are downvoting because they don't think this should be done. That's all very well, but this does actually answer the question. –Sam Meldrum Dec 3 '08 at 17:41 3 @SamMeldrum because this will not catch all exceptions. Only those thrown in the UI thread. –Crono Mar 14 '14 at 18:51 add a comment| up vote 28 down vote I assume you are writing a Windows application in which case, yes, you can do this. I will leave the rights and wrongs of whether or not you should to others. There are already enough answers which look at this and I suggest you consider them carefully before you actually do this. Note, that this code will behave differently in the debugger than it does if you run the application directly (another reason not to do it perhaps). To get the application to show the messagebox and to continue on thereafter you will need to run the application from explorer, not from visual studio. Create a new Windows forms application. The code in Program.cs looks something like this: using System; using System.Collections.Generic; using System.Linq; using System.Threading; using System.Windows.Forms; namespace WindowsFormsApplication2 { static class Program { ///

I've read a few C# books now so I've got a relatively good understanding of what language features C# has to handling in asp deal with exceptions. They're all quite theoretical however so what I haven't got yet is a feel for how to translate the basic concepts into a good exception-handling model in my application. Would anyone like to share any pearls of wisdom on the subject? Post any common mistakes you've seen newbies like myself make, and any general advice on handling exceptions in a way that will my application more stable and robust. The main things I'm currently trying to work out are: When should I re-throw an exception? Should I try to have a central error-handling mechanism of some kind? Do handling exceptions which might be thrown have a performance hit compared with pre-emptively testing things like whether a file on disk exists? Should all executable code be enclosed in try-catch-finally blocks? Are there any times when an empty catch block might be acceptable? All advice gratefully received! c# winforms exception-handling share|improve this question edited Oct 13 '11 at 13:56 Otiel 9,63094491 asked Oct 8 '08 at 16:13 Jon Artus 2,390103039 add a co
