Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework exception handling in asp net c# with example 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

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 https://msdn.microsoft.com/en-us/library/24395wz3.aspx 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"); } // For other kinds of errors give the u

There are enormous articles written earlier for this topic. I have tried writing this article for beginners explaining these concepts in simple language and step-by-step.This is a very basic article for beginners that show exception handling and error handling techniques in ASP.NET.Where there are codes, the chances for exceptions / error always exist so it is very important for developers when developing web applications to understand the errors and implement the error handling techniques to avoid breaking pages or providinig unhandled errors to end uses.What Exceptions areGuys, the MSDN says that an exception is an error condition or unexpected behavior encountered by an executing program. Exceptions can be raised because of a fault in your code or in code that you call (su
