範例

下列範例會建立 MediaElement 物件，並回應其 MarkerReached 事件。 每次到達時間軸標記時，此範例會顯示時間軸標記的時間、類型和文字值。

<MediaElement Name="Media" Source="video.mp4" MarkerReached="Media_MarkerReached" />
<TextBlock Name="txOutput" />

private void Media_MarkerReached(object sender, TimelineMarkerRoutedEventArgs e)
{
    txOutput.Text =
        string.Format("{0},{1},{2}", e.Marker.Time, e.Marker.Text, e.Marker.Type);
}
