예제

다음 예제에서는 폼을 ThreadException 클릭하여 이벤트를 발생시키는 방법을 button1 설명합니다. 이 예제에서는 두 개의 클래스를 만듭니다. 클래스는 ErrorHandler 폼과 이벤트를 발생시키는 단추를 만듭니다. 클래스는 CustomExceptionHandler 예외를 처리하는 메서드를 제공합니다.

Main 클래스에서 ErrorHandler 코드는 예외 처리 클래스의 새 instance 만듭니다. 즉, 의 CustomExceptionHandlerinstance. 이벤트를 인스턴스에 추가 되는 다음 하 고 애플리케이션이 실행 됩니다.

클래스의 OnThreadException 메서드에서 CustomExceptionHandler 예제에서는 문을 사용하여 try...catch...finally 예외를 처리합니다. 메서드는 ShowThreadExceptionDialog 표시할 메시지를 만들고 메시지 상자에 표시합니다.
