本文实例讲述了c#使用dataset读取xml文件动态生成菜单的方法。分享给大家供大家参考。具体实现方法如下:
step 1:form1 上添加一个toolstripcontainer控件
step2:实现代码
private void form2_load(object sender, eventargs e) { cmenuex menu = new cmenuex(); string spath = "d://menu.xml";//xml的内容 if (menu.fileexit()) { menu.loadallmenu(spath, toolstripcontainer1); //读取xml来加载菜单 } else { messagebox.show("xml文件加载失败!"); } } /// <summary> /// 菜单读取类 /// </summary> public class cmenuex { private string _path; /// <summary> /// 设置xml配置文件路径 /// </summary> public string path { get { return _path; } set { _path = value; } } /// <summary> /// 判断文件是否存在 /// </summary> /// <returns>文件是否存在</returns> public bool fileexit() { if (file.exists(_path)) { return true; } else return false; } /// <summary> /// 加载菜单 /// </summary> /// <param name="menustrip">母菜单对象</param> public void loadallmenu(string sxmlpath, toolstripcontainer ptoolstripcontainer) { dataset ds = new dataset(); ds.readxml(sxmlpath, xmlreadmode.auto); string toolstrippaneltype = "toptoolstrippanel"; //查找所有最初一级的菜单 dataview dvmenuoptions = new dataview(ds.tables["menuoptions"], "parentlevel=id and toolstrippaneltype='" + toolstrippaneltype + "'", "displayorder asc", dataviewrowstate.currentrows); string sparentlevel = ""; toolstrippanel tsptop = ptoolstripcontainer.toptoolstrippanel; tsptop.dock = dockstyle.top; toolstrip tstop = new toolstrip(); tsptop.join(tstop); //绑定toolstrip foreach (datarowview rvmain in dvmenuoptions) //循环得到主菜单 { sparentlevel = rvmain["parentlevel"].tostring(); toolstripmenuitem tsitemparent = new toolstripmenuitem(); tsitemparent.text = rvmain["text"].tostring(); tsitemparent.name = rvmain["name"].tostring(); tstop.items.add(tsitemparent);//添加父菜单 //查找父菜单下的所有子菜单 dataview dvsub = new dataview(ds.tables["menuoptions"], "parentlevel<>id and parentlevel='" + sparentlevel + "'", "displayorder", dataviewrowstate.currentrows); foreach (datarowview rvsub in dvsub) { toolstripmenuitem itemsub = new toolstripmenuitem(); itemsub.text = rvsub["text"].tostring() + " " + rvsub["shortcutkeys"].tostring(); //为菜单添加单击事件 itemsub.click += new eventhandler(toolsubitem_click); //菜单响应函数 itemsub.name = rvsub["method"].tostring(); tsitemparent.dropdownitems.add(itemsub); } } } //自定义消息响应函数 void toolsubitem_click(object sender, eventargs e) { //创建菜单调用方法类的实例 menumethod menumethod = new menumethod(); type type = menumethod.gettype(); //动态获取方法对象 methodinfo mi = type.getmethod(((toolstripmenuitem)sender).name); //调用指定方法 if (mi != null) { mi.invoke(menumethod, null); } } /// <summary> /// 菜单的方法列表类 /// </summary> class menumethod { public void new() { messagebox.show("new"); } public void open() { messagebox.show("open"); } } }
