Answer 1

工具箱选择项，加载那个dll,控件就出现在工具箱中了，还得引用类名空间，将控件拉进来就行，相关操作网上都有，给你来点代码参考，以前做了一个这样的，右边播放器，右边是一个列表，他这个支持的格式一般，有的格式不能放，  public partial class MP3播放器 : Form
    {
        
        
        public MP3播放器()
        {
            InitializeComponent();
            listBox1.ForeColor = System.Drawing.Color.Red;
            axMediaPlayer.EndOfStream += new AxMediaPlayer._MediaPlayerEvents_EndOfStreamEventHandler(this.EndOfStream);
        }        private void Form1_Load(object sender, EventArgs e)
        {
            this.loadlistbox();
            this.WindowState = System.Windows.Forms.FormWindowState.Minimized;
            
        }
        private void loadlistbox()
        {
            string[] fileGroup = Directory.GetFiles("F:\\MP3\\4");
            string pattern = @"\.mp3|\.wma$";
            foreach (string i in fileGroup)
            {
                if (Regex.IsMatch(i, pattern))
                {
                    listBox1.Items.Add(i);
                }
            }
            this.listBox1.SelectedIndex = 0;
        }
        private void EndOfStream(object sender, AxMediaPlayer._MediaPlayerEvents_EndOfStreamEvent e)
        {
            try
            {
                int count = listBox1.Items.Count;
                if (listBox1.SelectedIndex == count - 1)
                {
                    listBox1.SelectedIndex = 0;
                }
                else
                {
                    listBox1.SetSelected(listBox1.SelectedIndex + 1, true);
