C#擷取系統當前滑鼠的圖案範例程式碼

C#擷取系統當前滑鼠的圖案代碼如下：

using System.Runtime.InteropServices; [StructLayout(LayoutKind.Sequential)]struct CURSORINFO{    public int cbSize;    public int flags;     public IntPtr hCursor;    public Point ptScreenPos;} [DllImport("user32.dll")]static extern bool GetCursorInfo(out CURSORINFO pci); private const int CURSOR_SHOWING= 0x00000001; private void button1_Click(object sender, EventArgs e){     CURSORINFO vCurosrInfo;    vCurosrInfo.cbSize = Marshal.SizeOf(typeof(CURSORINFO));    GetCursorInfo(out vCurosrInfo);    if ((vCurosrInfo.flags & CURSOR_SHOWING) != CURSOR_SHOWING) return;    Cursor vCursor = new Cursor(vCurosrInfo.hCursor);    Graphics vGraphics = Graphics.FromHwnd(Handle);    Rectangle vRectangle = new Rectangle(0, 0, 32, 32);    vGraphics.FillRectangle(new SolidBrush(BackColor), vRectangle);    vCursor.Draw(vGraphics, vRectangle);}
