你好，
一般我们可以用 DirectShow，在.NET 程序中，我们可以使用如下的库去访问 DirectShow API:
#DirectShow.Net Library
http://directshownet.sourceforge.net/index.html
做为另一种替代，可以使用OpenCV，它相较于DirectShow，可以更快速地访问你的摄像头：http://sourceforge.net/projects/opencvlibrary/?source=directory
这个项目是对OpenCV的.NET封装：http://code.google.com/p/opencvdotnet/
