推荐答案

有没有办法实时获取当前屏幕

Is there a way to get the current screen real-time

当然，您可以使用 GraphicsCapturePicker 选择要捕获的窗口，并使用屏幕捕获 api 使用 FrameArrived 事件获取实时帧.

Sure, you could use GraphicsCapturePicker to pick window that you want to capture, and use screen capture api the get real time frame with FrameArrived event.

_framePool.FrameArrived += (s, a) =>
{
    // The FrameArrived event fires for every frame on the thread that
    // created the Direct3D11CaptureFramePool. This means we don't have to
    // do a null-check here, as we know we're the only one  
    // dequeueing frames in our application.  

    // NOTE: Disposing the frame retires it and returns  
    // the buffer to the pool.
    using (var frame = _framePool.TryGetNextFrame())
    {
        // We'll define this method later in the document.
        ProcessFrame(frame);
    }  
};

这里是官方文档你可以参考.
