如何在C#中添加音乐？

using System;
using System.Windows.Forms;
using System.Media;

namespace MusicPlayer
{
    public partial class Form1 : Form
    {
        private SoundPlayer player;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "音频文件|*.wav;*.mp3";
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                string fileName = openFileDialog.FileName;
                player = new SoundPlayer(fileName);
                player.Load();
                lblStatus.Text = "音乐已加载";
            }
        }

        private void btnPlay_Click(object sender, EventArgs e)
        {
            if (player != null)
            {
                player.Play();
                lblStatus.Text = "正在播放音乐";
            }
        }

        private void btnPause_Click(object sender, EventArgs e)
        {
            if (player != null)
            {
                player.Pause();
                lblStatus.Text = "音乐已暂停";
            }
        }

        private void btnStop_Click(object sender, EventArgs e)
        {
            if (player != null)
            {
                player.Stop();
                lblStatus.Text = "音乐已停止";
            }
        }
    }
}
