예제

다음 예제에서는 백그라운드 작업에 조건을 추가하여 SystemTrigger 에 표시된 예제를 확장합니다.

//
// A friendly task name.
//
string name = "ExampleTaskName";

//
// Must be the same entry point that is specified in the manifest.
//
string taskEntryPoint = "ExampleNamespace.ExampleTaskName";

//
// A system trigger that goes off whenever the time zone is changed, or a change occurs with daylight savings time.
//
IBackgroundTrigger trigger = new SystemTrigger(SystemTriggerType.TimeZoneChange, false);

//
// A system condition indicating that the background task shouldn't run until the user is present.
//
SystemCondition condition = new SystemCondition(SystemConditionType.UserPresent)

//
// Builds the background task.
//
BackgroundTaskBuilder builder = new BackgroundTaskBuilder();

builder.Name = name;
builder.TaskEntryPoint = taskEntryPoint;
builder.SetTrigger(trigger);
builder.AddCondition(condition);

//
// Registers the background task, and get back a BackgroundTaskRegistration object representing the registered task.
//
BackgroundTaskRegistration task = builder.Register();

설명

참고

이 클래스는 민첩하지 않으므로 스레딩 모델 및 마샬링 동작을 고려해야 합니다. 자세한 내용은 스레딩 및 마샬링(C++/CX) 및 다중 스레드 환경(.NET)에서 Windows 런타임 개체 사용을 참조하세요.

생성자

SystemCondition(SystemConditionType)

시스템 조건의 새 instance 초기화합니다.

속성
