C#获取MP3信息

首先引用COM组件
Microsoft Shell Controls And Automation
这里需要注意
DLL的属性Embed Interop Type 设为False
否则会引起互操作类型异常
代码如下
ShellClass sh = new ShellClass();
Folder dir = sh.NameSpace(Path.GetDirectoryName(sFile));
FolderItem item = dir.ParseName(Path.GetFileName(sFile));
string det = dir.GetDetailsOf(item, iCol);
iCol 对应文件详细属性汇总
