我想知道是否有任何的方式来捕捉拍摄我的桌面使用.NET的视频（截屏）？我不是在寻找一个截屏软件，而只是一种技术，可以让我产生自己我的桌面视频。

I would like to know if there is any way to capture a to capture a video (screencast) of my desktop with .NET? I am not looking for a screencast software, but simply a technique that would allow me to generate myself a video of my desktop.

我想到服用多种截图，但我不知道我怎么会用图像序列...

I thought of taking multiple screenshots, but I am not sure of how I could generate programmatically a video with a sequence of images...

是否有人有一个想法？

谢谢！

下面是另一种方法，使用托管DirectX
