我试图通过以下方式获得价值,但没有奏效:
private void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{
TaskbarManager.Instance.SetProgressState(TaskbarProgressBarState.Normal);
axWindowsMediaPlayer1.Ctlcontrols.play();
axWindowsMediaPlayer1.Ctlcontrols.currentItem =
axWindowsMediaPlayer1.currentPlaylist.Item[listBox1.SelectedIndex];
backgroundWorker2.RunWorkerAsync();
}
private void backgroundWorker2_DoWork(object sender, DoWorkEventArgs e)
{
double val = 100*axWindowsMediaPlayer1.Ctlcontrols.currentPosition/axWindowsMediaPlayer1.currentMedia.duration;
TaskbarManager.Instance.SetProgressValue((int)val,100);
}
我也不确定,我应该在哪里停止进度,但我想现在考虑还为时过早,因为无论如何我都无法让进度正常工作。
问题是我如何使用 backgroundWorker 或我如何更新值,还是其他问题?
提前致谢,

编辑:
private void TaskbarProgressValueDeterminator()
{
TaskbarManager.Instance.SetProgressState(TaskbarProgressBarState.Normal);
while (axWindowsMediaPlayer1.Ctlcontrols.currentPosition < axWindowsMediaPlayer1.currentMedia.duration)
{
TaskbarManager.Instance.SetProgressValue((int)(100 * axWindowsMediaPlayer1.Ctlcontrols.currentPosition / axWindowsMediaPlayer1.currentMedia.duration), 100);
}
TaskbarManager.Instance.SetProgressState(TaskbarProgressBarState.NoProgress);
}
