C# Language Exception Handling Unhandled and Thread Exception
Example
AppDomain.UnhandledException This event provides notification of uncaught exceptions.It allows the application to log information about the exception before the system default handler reports the exception to the user and terminates the application.If sufficient information about the state of the application is available, other actions may be undertaken — such as saving program data for later recovery.Caution is advised, because program data can become corrupted when exceptions are not handled.
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
private static void Main(string[] args)
{
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(UnhandledException);
}
Application.ThreadException This event allows your Windows Forms application to handle otherwise unhandled exceptions that occur in Windows Forms threads. Attach your event handlers to the ThreadException event to deal with these exceptions, which will leave your application in an unknown state. Where possible, exceptions should be handled by a structured exception handling block.
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
private static void Main(string[] args)
{
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(UnhandledException);
Application.ThreadException += new ThreadExceptionEventHandler(ThreadException);
}
And finally exception handling
static void UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
Exception ex = (Exception)e.ExceptionObject;
// your code
}
static void ThreadException(object sender, ThreadExceptionEventArgs e)
{
Exception ex = e.Exception;
// your code
}
