Complete Example for Error 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 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 exten

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 errors while processing a https://msdn.microsoft.com/en-us/library/24395wz3.aspx 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"); } // For other kinds of errors give the user some inf

Join them; it only takes a minute: Sign up How do you log errors (Exceptions) in your ASP.NET apps? up vote 21 down error handling vote favorite 12 I'm looking for the best way to log errors in an ASP.NET application. I want to be able to receive emails when errors occurs in my application, with detailed information about the Exception and the current Request. In my company we used to have our own ErrorMailer, catching everything in the Global.asax Application_Error. It was "Ok" but not very flexible nor configurable. We swithed recently to NLog. error handling and It's much more configurable, we can define different targets for the errors, filter them, buffer them (not tried yet). It's a very good improvement. But I discovered lately that there's a whole Namespace in the .Net framework for this purpose : System.Web.Management and it can be configured in the healthMonitoring section of web.config. Have you ever worked with .Net health monitoring? What is your solution for error logging? Thanks, Vincent asp.net error-handling nlog health-monitoring share|improve this question edited Jan 23 '09 at 9:45 edosoft 9,6672063103 asked Aug 15 '08 at 4:05 Costo 2,84262235 I've also seen System.Web.Management, but I've never used it. I'd love to hear any feedback on whether it works well. –Ben Mills Dec 4 '08 at 22:00 add a comment| 8 Answers 8 active oldest votes up vote 25 down vote accepted I use elmah. It has some really nice features and here is a CodeProject article on it. I think the StackOverflow team uses elmah also! share|improve this answer answered Aug 15 '08 at 4:34 Dale Ragan 16.1k24469 3 I wrote an ELMAH Tutorial last year, which I think describes this scenario in more detail than the CodeProject article. –ThomasArdal Sep 27 '14 at 18:30 add a comment| up vote
