win7怎么把一张图片放到桌面上,但不是变成背景

Visual Studio C#编程可以实现往桌面绘制图片

    public class 桌面 {

[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]

        public static extern IntPtr GetDesktopWindow();

        [DllImport("user32.dll", EntryPoint = "GetDCEx", CharSet = CharSet.Auto, ExactSpelling = true)]

        public static extern IntPtr GetDCEx(IntPtr hWnd, IntPtr hrgnClip, int flags);

        public static Graphics 返回桌面画纸() {

            IntPtr desk = GetDesktopWindow();

            IntPtr deskDC = GetDCEx(desk, IntPtr.Zero, 0x403);

            return Graphics.FromHdc(deskDC);

        }

}

//把下面代码加入Form1_Load中

桌面.返回桌面画纸().DrawImage(new Bitmap(@"C:\123.bmp"), new Rectangle(0,0, 500,500)); 

this.Hide(); //隐藏本窗体。

做成exe运行即可。
