提问by Sneakybastardd
I have a listbox that contains all media files that has to be played. How do make media player play 1 by one? This code plays 1 song but foreach is supposed to play all files, but I quess that is because it doesn't wait till media ended.. this code:
我有一个列表框，其中包含必须播放的所有媒体文件。如何让媒体播放器1个播放？此代码播放 1 首歌曲，但 foreach 应该播放所有文件，但我怀疑这是因为它不会等到媒体结束.. 这段代码：
Listbox = listBox3
Listbox = listBox3
listBox3Dict[s]= string for all files in listbox
listBox3Dict[s]= 列表框中所有文件的字符串
Dictionary<string, string> listBox3Dict = new Dictionary<string, string>();
> private bool listbox3job()
> {
> AxWMPLib.AxWindowsMediaPlayer axWmp = wfh.Child as AxWMPLib.AxWindowsMediaPlayer;
> {

> {

> if (listBox3Dict.ContainsKey(s))

WMPLib.IWMPPlaylist playlist = axWindowsMediaPlayer1.newPlaylist("myPlaylist", string.Empty);
// you can add songs to url on for loop
WMPLib.IWMPMedia temp = this.axWindowsMediaPlayer1.newMedia(listBox3Dict[s]); //Load media from URL.
playlist.appendItem(temp); //Add song to playlist.
// after you add all songs set the new playlist
this.axWindowsMediaPlayer1.settings.autoStart = true; //not necessary
this.axWindowsMediaPlayer1.currentPlaylist = playlist; //Set media player to use the playlist.

what you can do is create player list and start play that list
您可以做的是创建播放器列表并开始播放该列表
private bool listbox3job()
{
AxWMPLib.AxWindowsMediaPlayer axWmp = wfh.Child as AxWMPLib.AxWindowsMediaPlayer;
WMPLib.IWMPPlaylist playlist = axWmp.newPlaylist("myPlaylist", string.Empty);
foreach (var selected in listBox1.Items)
{
string s = selected.ToString();
if (listBox3Dict.ContainsKey(s))
{
WMPLib.IWMPMedia temp = axWmp.newMedia(listBox3Dict[s]); //Load media from URL.
playlist.appendItem(temp); //Add song to playlist.
}
}
axWmp.settings.autoStart = true; //not necessary
axWmp.currentPlaylist = playlist; //Set media player to use the playlist.
return true;
}

Earlier I was working on a set of speech files in a list. I used PlayStateChange event. From this event you can find MediaEnded state where you can reassign the playfile to next item in the list.
早些时候，我正在处理列表中的一组语音文件。我使用了 PlayStateChange 事件。在此事件中，您可以找到 MediaEnded 状态，您可以在其中将播放文件重新分配给列表中的下一项。
