Troubleshooting an ASP .NET Application

Error Handling

• Error handling is a collection of techniques that allow you to identify errors
  in your code.
• Many errors are caused by incorrect syntax or spelling errors.
• These are easily handled by Visual Studio .NET's intellisense feature.
• To handle errors that arise in execution, you can write code that interprets error
  messages and that executes when an error is detected, and generates custom
  error messages and global error handlers.
