Study Notes
Purpose of Error Handling in ASP.NET
- Ensure application reliability by managing unexpected issues without crashing.
- Maintain a seamless user experience by preventing abrupt program terminations.
Automatic Exception Handling Mechanism
- ASP.NET provides a built-in feature called "Global.asax" that automatically catches unhandled exceptions.
- Utilize the Application_Error event to handle errors globally across the application.
Best Practices for Logging Errors
- Implement structured logging to capture detailed error information for troubleshooting.
- Store error logs in a secure and accessible location to facilitate easy monitoring and analysis.
Consequences of Unhandled Errors
- Unhandled errors can lead to application crashes, resulting in a negative user experience.
- Potential exposure of sensitive information through error messages if not properly managed.
User-Friendly Error Message Approach
- Use custom error pages to display friendly messages rather than technical details.
- Implement the
customErrorsmode in web.config to direct users to specific error handling pages based on the HTTP status code.
