AE二次开发中，AxMapControl中地图复制到AxPageLayout控件中的代码

调用该方法即可实现

        /// <summary>
        /// 显示页面布局控件
        /// </summary>
        public void ShowMapPageLayout()
        {
            //给页面布局控件复制地图
            IObjectCopy objectCopy = new ObjectCopyClass();
            object overwriteMap = pageLayoutControl.ActiveView.FocusMap;
            objectCopy.Overwrite(mapControl.Map, ref overwriteMap); 
        }
