Timer.AutoReset 속성

Source:

Timer.cs

Timer에서 Elapsed 이벤트를 한 번만(false) 발생시켜야 하는지 반복해서(true) 발생시켜야 하는지 나타내는 부울을 가져오거나 설정합니다.

public:
 property bool AutoReset { bool get(); void set(bool value); };

public bool AutoReset { get; set; }

member this.AutoReset : bool with get, set

Public Property AutoReset As Boolean

속성 값

Boolean

간격이 경과할 때마다 Timer에서 Elapsed 이벤트를 발생시켜야 하면 true이고, 첫 번째 간격이 경과한 후 한 번만 Elapsed 이벤트를 발생시켜야 하면 false입니다. 기본값은 true입니다.

예제

다음 예제에서는 이벤트가 1.5초 후에 실행되는 을 만듭니다 TimerElapsed . 그러면 해당 이벤트 처리기가 콘솔에 "헬로 월드!"를 표시합니다.

설명

가 이 falseStart 면 AutoReset 수를 다시 시작하려면 메서드를 호출해야 합니다.

간격을 다시 설정하면 이벤트가 발생할 때 Elapsed 영향을 줍니다. 예를 들어 간격을 5초로 설정한 다음 속성을 true로 설정 Enabled 하면 횟수가 설정된 시간에 Enabled 시작됩니다. 개수가 3초일 때 간격을 10초 Elapsed 로 다시 설정하면 속성이 로 설정된 true후 처음으로 13초 동안 Enabled 이벤트가 발생합니다.
