一个简单的基于XML的模块集成框架

1. 预备一个xml文件

xmlmenu
1%26lt;Menu%26gt;
2 %26lt;MenuItem Name="系统治理" AssemblyName="" FormTag="FALSE" AddToolbar="FALSE"%26gt;
3 %26lt;MenuItem Name="权限治理" ShortCut="" Image="" AssemblyName="" FormTag="FALSE" AddToolButton="FALSE"%26gt;
4 %26lt;MenuItem Name="系统权限治理" ShortCut="" Image="password.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmSysRight,IntePLM.TyRightWinUI" FormTag="TRUE" AddToolButton="FALSE"/%26gt;
5 %26lt;MenuItem Name="权限规则定义" ShortCut="" Image="right.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmRightRule,IntePLM.TyRightWinUI" FormTag="TRUE" AddToolButton="FALSE"/%26gt;
6 %26lt;MenuItem Name="权限日志" ShortCut="" Image="doc_yellow_edit.png" AssemblyName="HustCAD.IntePLM.WinUI.FrmRightLog,IntePLM.TyRightWinUI" FormTag="TRUE" AddToolButton="FALSE"/%26gt;
7 %26lt;/MenuItem%26gt;
8%26lt;/Menu%26gt;
2.预备一个xml schemal文件来验证xml文件

%26lt;?xml version="1.0" encoding="UTF-8"?%26gt;

}
这里面用到了delegate，最重要的函数是加载菜单的函数和OnPluginClick函数。

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。

假如您对这个框架感爱好可以邮件 piyanrong@gmail.com。
