推荐答案

也许以间隔速率捕获桌面会更容易，然后使用插件或外部库将每个图像编码为视频文件。

AviFile库的简单C＃包装器 [ ^ ]



关于如何捕获你的destop，这很容易。您创建一个具有屏幕大小的位图，然后创建位图中的图形，然后复制屏幕并保存：

Maybe it would be easier to capture the desktop at interval rates, and then encode each image into a video file using a plugin or an external library.

A Simple C# Wrapper for the AviFile Library[^]

About how to capture your destop, it's easy. You create a bitmap with the size of the screen, then a Graphics from the bitmap, and then copy the screen and save it:

private void TakeScreenShot()
{
    Bitmap bmpScreenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb);

    Graphics gfxScreenshot = Graphics.FromImage(bmpScreenshot);

    gfxScreenshot.CopyFromScreen(0, 0, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);

    //Change the ImageFormat to jpeg to save hard disk or keep it in Tiff
    //for higher resolution
    bmpScreenshot.Save("Dependencies\\temp.tif", ImageFormat.Tiff);
    bmpScreenshot = null;
}

您可以虚构地使用VirtualDub等外部程序。也许你可以为它制作一个脚本，并从你的程序中运行它。我知道这不是你打算这样做的方式，但这是另一种方式。

You can adictionally use an external program like VirtualDub. Maybe you can make a script for it, and run it from your program. I know this is not the way you're intended to do it, but it's another way.
