推荐答案

我怀疑C#中有没有更快的方法，您也许可以使用C ++或互操作来更快地完成某些工作.归根结底，我能看到的唯一更快的方法是，您可以直接访问用于屏幕的内存，还是直接复制它而无需沿途创建Image对象.

I doubt there''s any faster way in C#, you may be able to do something faster using C++ or interop. At the end of the day, the only faster way I can see is if you can access the memory used for the screen directly, or just copy it directly without creating an Image object along the way.
