Global Error Handling

Global error handling is a technique used in ASP.NET to handle unhandled exceptions that occur in an application. When an unhandled exception occurs, ASP.NET normally displays an error page to the user that includes information about the exception, the stack trace, and other debugging information. This can be helpful for developers, but it can also expose sensitive information and provide a poor user experience.

To implement global error handling in an ASP.NET application, you can use the Application_Error event in the Global.asax file. This event is raised whenever an unhandled exception occurs in the application. You can handle the event by writing code to log the exception, send an email notification, or redirect the user to a custom error page.

Here’s an example of how to implement global error handling in an ASP.NET application:

void Application_Error(object sender, EventArgs e)

{

Exception ex = Server.GetLastError();

// Log the exception

// Send an email notification

// Redirect the user to a custom error page

}

In this example, the Application_Error method is called whenever an unhandled exception occurs. The Server.GetLastError() method is used to get the details of the exception. You can then use this information to log the exception, send an email notification, or redirect the user to a custom error page.

To redirect the user to a custom error page, you can use the Server.Transfer method to transfer control to the error page. For example:

void Application_Error(object sender, EventArgs e)

{

Exception ex = Server.GetLastError();

// Log the exception

// Send an email notification

Server.Transfer(“~/Error.aspx”);

} By implementing global error handling in your ASP.NET application, you can provide a better user experience and ensure that sensitive information is not exposed to users.
