예제
다음 예제에서는 사용 ConsoleCancelEventArgs 하는 방법에 설명 합니다 클래스를 처리 하는 이벤트입니다.
using namespace System;

// terminating.

// Announce the new value of the Cancel property.

설명
사용자를 동시에 눌러 콘솔 애플리케이션 프로세스를 중단할 수는 Control 보조키 및 C 콘솔 키 (Ctrl + C) 또는 Control 보조키 및 Break 콘솔 키 (Ctrl + Break). 따라서 .NET은 이벤트의 이벤트 처리기에 Console.CancelKeyPress 개체를 제공하여 ConsoleCancelEventArgs 프로세스를 취소할지 여부를 지정합니다.
속성이 Cancel 이벤트 처리기에서 로 true
설정되면 프로세스가 다시 시작되고, 그렇지 않으면 프로세스가 종료됩니다. 기본적으로 속성의 ConsoleCancelEventArgs 값은 이며 false
프로세스가 종료됩니다.
속성
Cancel |
Control 보조키와 C 콘솔 키(Ctrl+C) 또는 Ctrl+Break 키를 동시에 누르면 현재 프로세스가 종료되는지 여부를 나타내는 값을 가져오거나 설정합니다. 기본값은 현재 프로세스를 종료하는 |
SpecialKey |
현재 프로세스를 중단한 보조키와 콘솔 키의 조합을 가져옵니다. |
메서드
Equals(Object) |
지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object) |
GetHashCode() |
기본 해시 함수로 작동합니다. (다음에서 상속됨 Object) |
GetType() |
현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object) |
MemberwiseClone() |
현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object) |
ToString() |
현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object) |
