1. 准备一个xml文件

xmlmenu

 1<Menu>
 2    <MenuItem Name="系统管理" AssemblyName="" FormTag="FALSE" AddToolbar="FALSE">
 3        <MenuItem Name="权限管理" ShortCut="" Image="" AssemblyName="" FormTag="FALSE" AddToolButton="FALSE">
 4            <MenuItem Name="系统权限管理" ShortCut="" Image="passWord.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmSysRight,IntePLM.TyRightWinUI"
  FormTag="TRUE" AddToolButton="FALSE"/>
 5            <MenuItem Name="权限规则定义" ShortCut="" Image="right.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmRightRule,IntePLM.TyRightWinUI" 
 FormTag="TRUE" AddToolButton="FALSE"/>
 6            <MenuItem Name="权限日志" ShortCut="" Image="doc_yellow_edit.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmRightLog,IntePLM.TyRightWinUI"
  FormTag="TRUE" AddToolButton="FALSE"/>
 7        </MenuItem>
8</Menu>

2.准备一个xml schemal文件来验证xml文件

<?xml version="1.0" encoding="UTF-8"?>

使用这个框架可以动态增加任意的层次的模块。

微软的CAB 使用Resigster site方式来增加模块,感觉不是很方便。
