C# 获取系统安装程序列表及卸载程序

       首先添加引用Microsoft.WindowsMobile.Configuration。往界面中拖入控件ListBox，
       下面为部分代码：

       

private XmlDocument doc;

        /// <summary>
        /// 列出PDA上已安装的程序
        /// </summary>
        /// <param name="lb">待填充列表</param>
        private void ListApps(ListBox lb)
        {
            doc = new XmlDocument();
            //具体原理还要学习下
            doc.LoadXml(@"<wap-provisioningdoc><characteristic-query 

type=""UnInstall"" /></wap-provisioningdoc>");
            XmlDocument ret = ConfigurationManager.ProcessConfiguration(doc, 

true);
            XmlNodeList list = ret.SelectNodes("//characteristic/characteristic");
            lb.Items.Clear();
            lb.SuspendLayout();
            foreach (XmlNode xn in list)
            {
                lb.Items.Add(xn.Attributes["type"].Value);
            }
            lb.ResumeLayout(false);
        }


        /// <summary>
        /// 对选中的程序卸载
        /// </summary>
        /// <param name="appName">程序名</param>
        private void UnInstall(string appName)
        {
            Cursor.Current = Cursors.WaitCursor;
            doc = new XmlDocument();
            string xml = @"
            <wap-provisioningdoc>
                <characteristic type=""UnInstall"" >
                    <characteristic type=""{0}"" >
                        <parm name=""uninstall"" value=""1"" />
                    </characteristic>
                </characteristic>
            </wap-provisioningdoc>";
            doc.LoadXml(string.Format(xml, appName));
            ConfigurationManager.ProcessConfiguration(doc,true);
            ListApps(listBox1);
            Cursor.Current = Cursors.Default;
        }

其实也可以用列举windows\AppMgr下的所有文件夹名（除Install文件夹外)，自己测

试了下，感觉有可行性。
