Exception Handling In Asp Net C# With Example
.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 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.GetT

Currently in my project I have a controller called Error with action methods HTTPError404(), HTTPError500(), and General(). They all accept a string parameter error. Using or modifying the code below. What is http://stackoverflow.com/questions/1171035/asp-net-mvc-custom-error-handling-application-error-global-asax the best/proper way to pass the data to the Error controller for processing? I would like to have a robust solution as possible. protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); Response.Clear(); HttpException httpException = exception as HttpException; if (httpException != null) { RouteData routeData = new RouteData(); routeData.Values.Add("controller", "Error"); switch (httpException.GetHttpCode()) { case 404: // page not found routeData.Values.Add("action", "HttpError404"); break; case 500: // server error routeData.Values.Add("action", "HttpError500"); break; default: routeData.Values.Add("action", "General"); break; } routeData.Values.Add("error", exception); // clear error on server Server.ClearError(); // at this point how to properly pass route data to error controller? } } c# asp.net asp.net-mvc error-handling user-experience share|improve this question edited Sep 10 '14 at 17:54 Oualid KTATA 52138 asked Jul 23 '09 at 11:07 aherrick 7,7081772115 add a comment| 9 Answers 9 active oldest votes up vote 80 down vote accepted Instead of creating a new route for that, you could just redirect to your controller/action and pass the information via querystring. For instance: protected void Application_Error(object sender, EventArgs e) { Exception exception = Server.GetLastError(); Response.Clear(); HttpException httpException = exception as Htt

Here's how it looks: Global.asax: protected void Application_Error(object sender, EventArgs e) { Exception ex = Server.GetLastError(); string path = "N/A"; if (sender is HttpApplication) path = ((HttpApplication) sender).Request.Url.PathAndQuery; string args = string.Format("Path: {0}", path); // Custom code that generates an HTML-formatted exception dump string message = Email.GenerateExceptionMessage(ex, args); // Custom code that sends an email to the dev team. Email.SendUnexpectedErrorMessage("Some App", message); } One "minor" problem, though - when I intentionally have a part of the code throw an exception in order to test this mechanism... public static void GetMuffinsByTopping(string topping) { throw new Exception("Test Exception!", new Exception("Test Inner Exception!!!")); // Actual repository code is unreachable while this test code is there } The front-end JavaScript is immediately intercepting an HTTP 500 request, but the global.asax.cs code noted above is not being reached (I set a breakpoint on the first executing line of the method.) Question: In what way can I get the "old" Application_Error handler to dispatch error emails, so that our team's developers can more easily debug our application? c# asp.net-web-api error-reporting share|improve this question asked Feb 27 '15 at 15:34 Andrew Gray 1,3701630 1 Y

I add the following to my Global.asax file: protected void Application_Error(object sender, EventArgs e) { Exception objErr = Server.GetLastError().GetBaseException(); Session["Test"] = "Message:" + objErr.Message.ToString(); } (The Session is only for tests. Im gonna use a database to log error, if i get this to work.) Then i try to throw an exception from my HomeController and my Home/Index View, but it only triggers Debug. public ActionResult Index() { ViewData["Message"] = "Welcome to ASP.NET MVC!"; throw (new Exception()); return View(); } In my Webconfig file i set a defaulterror page but it doesn't redirect to the view:
