从AE工具条命令中提取出图标文件(转)

for (int i = 0; i < this.axToolbarControl1.Count; i++)
            {
                System.Drawing.Bitmap bmp = System.Drawing.Image.FromHbitmap((IntPtr)axToolbarControl1.GetItem(i).Command.Bitmap);
                Color m_color = bmp.GetPixel(0, 0);
                bmp.MakeTransparent(m_color);
                string filename = axToolbarControl1.GetItem(i).Command.Name + ".ico";
                //目录下必须有这个文件夹
                bmp.Save(@"d:\temp\" + filename, System.Drawing.Imaging.ImageFormat.Icon);
            }
