C#2.0开发VS2005上的Pocket PC 2003游戏, 播放背景音乐怎么不行啊？

Question

我要实现的功能是在玩游戏时可以切换背景音乐。我先把三个音乐文件Music1.wav,Music2.wav,Music3.wav拖到资源文件了去。然后就敲下面的代码。

namespace PlayMusic
{
    class APIPlayer
    {
        private String File_Path;
        private Byte[] Res_Name;
        private enum PalyFlags
        {
            SND_SYNC = 0x0000,                      /* play synchronously (default) */
            SND_ASYNC = 0x0001,                     /* play asynchronously */
            SND_NODEFAULT = 0x0002,                 /* silence (!default) if sound not found */
            SND_MEMORY = 0x0004,                    /* pszSound points to a memory file */
            SND_LOOP = 0x0008,                      /* loop the sound until next sndPlaySound */
            SND_NOSTOP = 0x0010,                    /* don't stop any currently playing sound */
            SND_NOWAIT = 0x00002000,                /* don't wait if the driver is busy */
            SND_ALIAS = 0x00010000,                 /* name is a registry alias */
            SND_ALIAS_ID = 0x00110000,              /* alias is a predefined ID */
            SND_FILENAME = 0x00020000,              /* name is file name */
            SND_RESOURCE = 0x00040004               /* name is resource name or atom */
        }

        [DllImport("Coredll.dll")]
        private static extern int PlaySound(String lpszName, IntPtr hMod, int dwFlag);

        [DllImport("Coredll.dll")]
        private static extern int PlaySound(Byte[] szSound, IntPtr hMod, int dwFlag);

        public APIPlayer(string strFilename)
        {
            File_Path = strFilename;
        }

        public APIPlayer(Stream streamRes)
        {           
            Res_Name = new Byte[streamRes.Length];
            streamRes.Read(Res_Name, 0, (int)streamRes.Length);
        }

        public void Play()                                          // 播放音乐
        {
            if (!String.IsNullOrEmpty(File_Path))
            {
                ClearLastInfo();
                PlaySound(File_Path, IntPtr.Zero, (int)(PalyFlags.SND_ASYNC | PalyFlags.SND_FILENAME));                
            }
            else if (Res_Name != null)
            {
                ClearLastInfo();
                PlaySound(Res_Name, IntPtr.Zero, (int)(PalyFlags.SND_ASYNC | PalyFlags.SND_MEMORY));
            }
            else
            {
            }
        }

        public void Stop()                                        // 关闭音乐
        {
            ClearLastInfo();
            PlaySound(String.Empty, IntPtr.Zero, (int)(PalyFlags.SND_ASYNC | PalyFlags.SND_FILENAME)); // 找不到文件名就会播放静音了
        }

        private void ClearLastInfo()
        {
            File_Path = String.Empty;
            Res_Name = null;
        }
    }
}

            InitializeComponent();
        }

        APIPlayer myAPIPlayer;
        private void MI_Music1_Click(object sender, EventArgs e)   // 播放资源文件里的Music1.wav
        {          
            myAPIPlayer = new  APIPlayer(Resource.sMusic1);
            myAPIPlayer.Play(); // 怎么把资源转化成比特流啊？
        }

        private void MI_Music2_Click(object sender, EventArgs e)  // 播放资源文件里的Music2.wav
        {
            myAPIPlayer = new  APIPlayer(Resources.Music2);
            myAPIPlayer.Play(); // 怎么把资源转化成比特流啊？
        }

            }
        }
    }
}

问题，就是我这个方法不行(见注释)，谁能帮帮我吗？

Answer 1

我试过的代码，大家下载后在这基础上改装。真的用掉我一个月都搞不出来，没有想象中来的简单，请路过的挑战一下好吗？
