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>
public class CFileInfo
{
private string sFileName ="",
sFullFileName="",
