推荐答案

您可以使用DirectShow的API MediaDet 对象，通过DirectShow.NET包装库。请参见获取的视频长度为code样品，<一个href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd406887%28v=vs.85%29.aspx"><$c$c>get_StreamLength让你在秒的持续时间。这是假定Windows有MPEG-4多路分解器安装（前7需要第三方组件与Windows，我相信cezor同样适用于另一个答案，也可以自由地重新分配，虽然组件）。

You can use DirectShow API MediaDet object, through DirectShow.NET wrapper library. See Getting length of video for code sample, get_StreamLength gets you the duration in seconds. This assumes Windows has MPEG-4 demultiplexer installed (requires third party components with Windows prior to 7, I believe the same applies to another answer by cezor, there are free to redistribute components though).
