调用API函数播放嵌入的MP3文件

1.将MP3文件导入到VS中,并且设置为嵌入的资源: 

MP3文件

2.导入到资源中,C#中视MP3为文件类型,以Byte[]形式存储:

 

 

3.将该MP3文件设置为嵌入的资源:

 

4.最后创建一个新的窗体工程,在Load事件中调用Mp3类的方法即可播放音乐:

private void FormMain_Load(object sender, EventArgs e){ 　　//加载音乐 　　Mp3Player mp3 = new Mp3Player(Properties.Resources.music, Handle);　　//音乐开始播放 　　mp3.Open();}
