推荐答案

实际上.net有自己的方法来执行此操作： Graphics.CopyFromScreen [ ^ ]。我建议你参考这篇简单的文章来实现示例： TeboScreen：Basic C＃Screen Capture Application [ ^ ]

Actually .net has it''s own method to do it: Graphics.CopyFromScreen[^]. I suggest you consult this simple article for sample implementation: TeboScreen: Basic C# Screen Capture Application[^]
