[转]C#获取系统当前鼠标的图案

C#获取系统当前鼠标的图案代码如下:

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);
}

=============================================================================

自己是在扩展WebBrowser时使用的,使用WebBrowser+MSHTML写编辑器时,需要让浮动对象可以移动,而在移动时,如果是在做resize就不要移动,两个事件有些冲突,所以通过判断鼠标的状态来知道当前的用户操作是什么。
