首先新建 Base Command，如下图：
在TOCControl 右键添加该菜单项，注意LayerPropertiesCmd() 前面的文件位置，为当前该类所在的项目位置，默认为LayerPropertiesCmd() 。
IToolbarMenu.AddItem（）函数中的参数 第一个参数：菜单项的内容，功能实现。 第二个参数：对于一个工具定义多个 type 的时候，才会用到，每一个 int 代表一个新的实现。 第三个参数：索引值，在菜单项上面显示的位置。默认为 -1，按书写顺序排序。 第四个参数：是否开始一个新组，就是在其上面有一个“——”的效果。 第五个参数：显示样式。
//添加图层属性菜单项 m_menuLayer.AddItem(new AE_test1.class_AE.LayerPropertiesCmd(), -1, 2, true, esriCommandStyles.esriCommandStyleTextOnly);原文中没有引用using ESRI.ArcGIS.ArcMapUI;因此标记下。
