You do have to use interop and I don't know if you can edit tags, I've never needed to do that but it's pretty much a swiss army knife at least for getting media information from files.
你必须使用互操作，我不知道你是否可以编辑标签，我从来不需要这样做，但至少对于从文件中获取媒体信息来说，这几乎是一把瑞士军刀。

I've recently used Tag Lib Sharpto write some C# apps for cleaning up and maintaining my music library. I found the library very easy to use and although i've only used it for MP3's, it appears to support a range of other music/video formats.
我最近使用Tag Lib Sharp编写了一些 C# 应用程序来清理和维护我的音乐库。我发现该库非常易于使用，虽然我只将它用于 MP3，但它似乎支持一系列其他音乐/视频格式。

Looks like MediaInfo is read-only at this point, by the way: http://sourceforge.net/forum/message.php?msg_id=4241318&abmode=1
看起来 MediaInfo 在这一点上是只读的，顺便说一下：http: //sourceforge.net/forum/message.php?msg_id=4241318&abmode =1
Very cool project, though. It's fun finding out about all this cool stuff here on SO.
不过，非常酷的项目。在 SO 上找到所有这些很酷的东西很有趣。

I used COM interop to access DirectShow's Media Detectorfunctionality.
我使用 COM 互操作访问DirectShow 的媒体检测器功能。
This does work pretty well, but it's a right pain in the backside. You need to know lots about COM, win32 interop, and so on.
这确实工作得很好，但它是背面的正确疼痛。您需要了解很多关于 COM、win32 互操作等的知识。
You can also use DirectShowNetwhich should handle most of that for you, I just didn't want to lug that whole thing around when I was only interested in the MediaDetector part
你也可以使用DirectShowNet，它应该为你处理大部分事情，当我只对 MediaDetector 部分感兴趣时，我只是不想拖着整个事情
