定義

命名空間:
Windows.ApplicationModel.Background
編輯

這可讓您以程式設計方式從應用程式內觸發背景工作。

備註

重要

應用程式在任何指定時間只能向BackgroundTaskBuilder註冊一個ApplicationTrigger。

建構函式

ApplicationTrigger()

建立新的 ApplicationTrigger 類別

方法

RequestAsync()

這個方法會嘗試設定觸發程式並啟動已註冊的背景工作。
RequestAsync(ValueSet)

這個方法會嘗試設定觸發程式，並使用指定的引數啟動已註冊的背景工作。
