備註

PlaybackRate或DefaultPlaybackRate變更時引發RateChanged事件。

事件資料中未提供新的 PlaybackRate 或 DefaultPlaybackRate 值，無論屬性變更為何。 應用程式應該查詢RateChangedRoutedEventHandler內的PlaybackRate或DefaultPlaybackRate，以取得新的速率。

建構函式

RateChangedRoutedEventArgs()

初始化 RateChangedRoutedEventArgs 類別的新實例。

屬性

OriginalSource

取得引發事件之 物件的參考。 這通常是控制項的範本部分，而不是在應用程式 UI 中宣告的專案。
