我想从组合框中选择一首歌曲，将其添加到播放列表中，点击＆＃34;开始播放音乐＆＃34;播放列表将从上到下播放。按钮..
当您点击＆＃34;添加音乐到列表＆＃34;时，我想将组合框中的选定歌曲添加到列表视图中。按钮。当然，使用＆＃34;删除所选音乐＆＃34;按钮我可以从列表中删除歌曲。
所以我必须这样做，例如当我从组合框（Music1）中选择单击按钮（添加音乐到列表）时，它将显示ID 1音乐名称音乐1，当点击开始音乐按钮时它将执行void playmusic1（）;
我知道我只是将组合框中的文字添加到listview，但我不知道如何在那里获得方法...
我真的不知道如何编写“开始音乐”按钮（我考虑队列）以使用我的listView1逐个播放音乐。
我需要的只是收藏品或其他东西或队列。
主要问题是如何创建一个包含方法gorups的列表，然后执行所有这个列表（如您所见，我希望能够删除此列表中的所选元素）
如果我不解释，请问..
修改...
我认为最好的解决方案是这段代码：
public List<Action> musiclist = new List<Action>();
// buttton to add music to list view
int i = 0;
private void button_add_music_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex==0)
{
musiclist.Add(playmusic1);
add(i, comboBox1.Text);
}
if (comboBox1.SelectedIndex == 1)
{
musiclist.Add(playmusic2);
add(i, comboBox1.Text);
}
if (comboBox1.SelectedIndex == 2)
{
musiclist.Add(playmusic3);
add(i, comboBox1.Text);
}
if (comboBox1.SelectedIndex == 3)
{
musiclist.Add(playmusic4);
add(i, comboBox1.Text);
}
if (comboBox1.SelectedIndex == 4)
{
musiclist.Add(playmusic5);
add(i, comboBox1.Text);
}
}
private void button_to_Start_music_Click(object sender, EventArgs e)
{
foreach (Action func in musiclist)
{
func();
}
}

在我看来，这不是最好的方法，无论如何你可以在字典中使用委托。
public delegate void PlayMusic();
Dictionary<string, PlayMusic> dictOfDelegate = new Dictionary<string, PlayMusic>();
void CreateList()
{
dictOfDelegate.Add("Music 1", playmusic1);
dictOfDelegate.Add("Music 2", playmusic2);
...
}
void InvokeMethod(string item)
{
PlayMusic method = dictOfDelegate.First(x => x.Key == item).Value;
method.Invoke();
}

您可以创建一个类歌曲和一个可以随时添加或删除内容的列表。
int queueSize = 0;
int queueCurrent = 0;
List<Song> toPlay = new List<Song>();
class Manager
{
public void addSong(Song add)
{
toPlay.add(add);
queueSize++;
}
public void removeSong(int remove)
{
toPlay.RemoveAt(remove)
queueSize--;
}
public void playSong(int index)
{
Song play = toPlay[index]
WMPLib.WindowsMediaPlayer songPlayer = new WMPLib.WindowsMediaPlayer();
songPlayer.URL = play.FilePath;
wplayer.Controls.Play();
}
}
class Song
{
string FilePath;
string Name;
int Index;
public Song(string name, int index)
{
Name = name;
Index = index;
}
}
当然这需要更多的代码，但这应该可以解决您的问题。如果您有任何问题或看到任何修改，请在评论中告诉我。
编辑：OP正在寻找每种歌曲的硬编码方式，所以就在这里。此外，我不建议其他任何人寻找相同的答案。
class Songs
{
public void songOne()
{
string name = "songOne";
string path = "C:/songs/songone/
playSong(path);
}
public void songOne()
{
string name = "songTwo";
string path = "C:/songs/songtwo/
playSong(path);
}
// And all the other songs
public void playSong(string path)
{
WMPLib.WindowsMediaPlayer songPlayer = new WMPLib.WindowsMediaPlayer();
songPlayer.URL = path;
wplayer.Controls.Play();
}
}
