还有我加个进度条但是 进度条代码我不会添加阿

没试过,理论上应该是可以的。如果要加进度条的话那就在我昨天说的,你要先计算出整个音乐的长度,然后再对进度条进行处理。具体怎样用进度条的控件,请看书……
你可以通过这个类来实现,具体的方法你查一下msdn吧。
FileVersionInfo fileVer = FileVersionInfo.GetVersionInfo( 文件 );
这里可以获得公司名,版本号,语言版本,版权等等
如果你要获得作者名,标题、作者等的话就需要引入“Microsoft Shell Controls and Automation”这个COM,这个是由系统Shell32提供的,下面我提供一个类的源代码,你参考一下吧。
using Shell32; // Use this namespace after add the reference
/// <summary>
/// Returns the detailed Information of a given file.
/// </summary>

不过有点夸张,但都要谢谢楼主的帮助.
