用WindowsMediaPlayer控件写个WinForm播放器

用WindowsMediaPlayer控件写了一个小播放器，只是一个小尝试

首先要添加Windows Media Player到工具箱

右击工具箱->选择项(I)... -> 显示"选择工具箱项" -> COM组件 -> Windows Media Player wmp.dll 添加

然后拖了一个 Windows Media Player控件、两个按钮、一个ListBox。



附：

private void button1_Click(object sender, EventArgs e)
{
AddMusicToListBox(listBox1);
}

private void AddMusicToListBox(ListBox lb)
{
string[] files = GetMusicFiles();
if (files != null && files.Length > 0)
{
foreach (string file in files)
{
if (!lb.Items.Contains(file))
{
lb.Items.Add(file);
}
}
}
}

private string[] GetMusicFiles()
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;//设置 选择多个文件
ofd.InitialDirectory = @"G:\MUSIC";
ofd.Filter = "(MP3文件)|*.mp3";
if (ofd.ShowDialog() == DialogResult.OK)
{
return ofd.FileNames;
}
else
{
return null;
}
}

private void listBox1_DoubleClick(object sender, EventArgs e)
{
axWindowsMediaPlayer1.currentPlaylist.clear();
//MessageBox.Show(listBox1.SelectedItem.ToString());
WMPLib.IWMPMedia song = axWindowsMediaPlayer1.newMedia(listBox1.SelectedItem.ToString());
axWindowsMediaPlayer1.currentPlaylist.appendItem(song);
axWindowsMediaPlayer1.Ctlcontrols.play();
}

private void button2_Click(object sender, EventArgs e)
{
RemoveMusicFromListBox(listBox1);
}

private void RemoveMusicFromListBox(ListBox lb)
{
lb.Items.Remove(lb.SelectedItem);
}
