ApplicationTrigger 类

  • 参考

定义

命名空间:
Windows.ApplicationModel.Background
编辑

这样，就可以从应用程序内部以编程方式触发后台任务。

注解

重要

在任何给定时间，一个应用只能向 BackgroundTaskBuilder 注册一个 ApplicationTrigger。

构造函数

ApplicationTrigger()

创建新的 ApplicationTrigger 类

方法

RequestAsync()

此方法尝试设置触发器并启动已注册的后台任务。
RequestAsync(ValueSet)

此方法尝试设置触发器，并使用指定的参数启动已注册的后台任务。
