Question

我不知道如何正确地写一个标题，但我的意思是制作这样的东西：

public static MusicPlayer _Player = new MusicPlayer();

_Player.Play.Song(TestPath);

其中MusicPlayer是一个类，在那个类中，我想创建类似属性或其他类的东西，我不知道如何调用它，这将有两个方法。我现在的代码：

public class MusicPlayer
{
    //Variables, Methods and Properties in MusicPlayer
    //And then Play which can have two tipes of play.
    public static class Play
    {
        //This one should be called if I want to play one song
        public static void Song(String _path)[...]

        //And this one when I want to play from list, defined in MusicPlayer class
        public static void List()[...]
    }
}

Answer 1

你应该这样做：

public class MusicPlayer
{
    public class Player
    {
        public static void Song(String _path)[...]
        public static void List()[...]
    }

    private Player m_player = new Player();

    public Player Play
    {
        get { return m_player; }
    }
}

这定义了Player中的MusicPlayer类。此外，它还创建了一个Player类型的成员变量，以及一个允许您使用Player 的实例从外部访问MusicPlayer实例的属性：

var mplayer = new MusicPlayer(); mplayer.Play.Song(...);

如果您不想创建MusicPlayer的实例，也可以将其设为静态：

public class MusicPlayer { public class Player { public static void Song(String _path)[...] public static void List()[...] } private static Player m_player = new Player(); public static Player Play { get { return m_player; } } }

您现在可以使用MusicPlayer.Play.Song(...)而无需创建实例。

Answer 2

你可以做那样的事情

public class MusicPlayer
{
    public MusicPlayer()
    {
        Play = new Play();
    }
    public Play Play { get; private set; }

}

public class Play
{
    //This one should be called if I want to play one song
    public void Song(String _path){}

    //And this one when I want to play from list, defined in MusicPlayer class
    public void List() { }
}

然后使用like

new MusicPlayer().Play.Song("");

从类中的类调用方法
