AppBroadcastTrigger 類別

定義

命名空間:

Windows.ApplicationModel.Background

表示當應用程式開始播放廣播時，觸發背景工作執行的事件。

public ref class AppBroadcastTrigger sealed : IBackgroundTrigger

/// [Windows.Foundation.Metadata.Activatable(Windows.ApplicationModel.Background.IAppBroadcastTriggerFactory, 65536, "Windows.Media.Capture.AppBroadcastContract")]
/// [Windows.Foundation.Metadata.ContractVersion(Windows.Media.Capture.AppBroadcastContract, 65536)]
/// [Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
/// [Windows.Foundation.Metadata.Threading(Windows.Foundation.Metadata.ThreadingModel.Both)]
class AppBroadcastTrigger final : IBackgroundTrigger

[Windows.Foundation.Metadata.Activatable(typeof(Windows.ApplicationModel.Background.IAppBroadcastTriggerFactory), 65536, "Windows.Media.Capture.AppBroadcastContract")]
[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.Media.Capture.AppBroadcastContract), 65536)]
[Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
[Windows.Foundation.Metadata.Threading(Windows.Foundation.Metadata.ThreadingModel.Both)]
public sealed class AppBroadcastTrigger : IBackgroundTrigger

備註

重要

只有第一方應用程式應該使用此類別。

必須先在資訊清單中宣告背景工作，才能成功註冊。 這個類別的實例會傳遞至 其 Run 方法中的背景工作。
