如何使用Windows API捕获屏幕和鼠标指针？

我正在使用以下代码捕获位图中的屏幕。 屏幕被捕获，但我无法在屏幕上显示鼠标指针。 你能建议一些替代方法，以便捕获鼠标吗？

private Bitmap CaptureScreen() { // Size size is how big an area to capture // pointOrigin is the upper left corner of the area to capture int width = Screen.PrimaryScreen.Bounds.X + Screen.PrimaryScreen.Bounds.Width; int height = Screen.PrimaryScreen.Bounds.Y + Screen.PrimaryScreen.Bounds.Height; Size size = new Size(width, height); Point pointOfOrigin = new Point(0, 0); Bitmap bitmap = new Bitmap(size.Width, size.Height); { using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.CopyFromScreen(pointOfOrigin, new Point(0, 0), size); } return bitmap; } }

 [StructLayout(LayoutKind.Sequential)] struct CURSORINFO { public Int32 cbSize; public Int32 flags; public IntPtr hCursor; public POINTAPI ptScreenPos; } [StructLayout(LayoutKind.Sequential)] struct POINTAPI { public int x; public int y; } [DllImport("user32.dll")] static extern bool GetCursorInfo(out CURSORINFO pci); [DllImport("user32.dll")] static extern bool DrawIcon(IntPtr hDC, int X, int Y, IntPtr hIcon); const Int32 CURSOR_SHOWING = 0x00000001; public static Bitmap CaptureScreen(bool CaptureMouse) { Bitmap result = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format24bppRgb); try { using (Graphics g = Graphics.FromImage(result)) { g.CopyFromScreen(0, 0, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy); if (CaptureMouse) { CURSORINFO pci; pci.cbSize = System.Runtime.InteropServices.Marshal.SizeOf(typeof(CURSORINFO)); if (GetCursorInfo(out pci)) { if (pci.flags == CURSOR_SHOWING) { DrawIcon(g.GetHdc(), pci.ptScreenPos.x, pci.ptScreenPos.y, pci.hCursor); g.ReleaseHdc(); } } } } } catch { result = null; } return result; }

如果您不是在寻找当前正在使用的光标的EXACT副本，您可以使用以下代码，您只需在原始代码中添加一行即可！

 private Bitmap CaptureScreen() { // Size size is how big an area to capture // pointOrigin is the upper left corner of the area to capture int width = Screen.PrimaryScreen.Bounds.X + Screen.PrimaryScreen.Bounds.Width; int height = Screen.PrimaryScreen.Bounds.Y + Screen.PrimaryScreen.Bounds.Height; Size size = new Size(width, height); Point pointOfOrigin = new Point(0, 0); Bitmap bitmap = new Bitmap(size.Width, size.Height); { using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.CopyFromScreen(pointOfOrigin, new Point(0, 0), size); //Following code is all you needed! graphics.DrawIcon(new Icon("Sample.ico"),Cursor.Position.X-50,Cursor.Position.Y-50); //The reason I minus 50 in the position is because you need to "offset" the position. Please go check out the post WholsRich commented. } return bitmap; } } 

你可以上网并下载所有类型的图标。

或者使用ICO Convert制作自己的。

祝好运！
