Answer 1

用什么shell，不就是目录遍历吗http://jlj84237485.blog.163.com/blog/static/34929460201010401434877/

List<ProgramInfo> ProInfo = new List<ProgramInfo>();
            Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall", false);
            Microsoft.Win32.RegistryKey key2 = null;
            string softwareName, installLocation, IconPath;
            if (key != null)//判断对象存在
            {
                foreach (string keyName in key.GetSubKeyNames())//遍历子项名称的字符串数组
                {
                    key2 = key.OpenSubKey(keyName, false);//遍历子项节点                    if (key2 != null)
                    {
                        softwareName = key2.GetValue("DisplayName", "").ToString();//获取软件名
                        IconPath = key2.GetValue("DisplayIcon", "").ToString();//获取安装路径InstallLocation
                        installLocation = key2.GetValue("InstallLocation", "").ToString();
                        if (!string.IsNullOrEmpty(installLocation))
                        {
                            ProInfo.Add(new ProgramInfo()

            pictureBox1.Image = ProInfo[0].ProImage.ToBitmap();
 class ProgramInfo
        {
            public string ProName;
            public string ProPath;
            public string ProIconPath;
            public Icon ProImage;
        }安装程序图标获取和显示
private void BindDrives()
        {
            DriveInfo[] drvs = DriveInfo.GetDrives();
            foreach (DriveInfo drv in drvs)
            {
                TreeNode root = new TreeNode();
                root.Text = drv.Name;
                root.Tag = drv.RootDirectory.ToString();

                    if (files.Length > 0) //有子节点，先添加一个空节点
                    {
                        root.Nodes.Add("emptyNode", string.Empty);
                    }
                }
            }
        }        //展开节点，移除以前的空节点，加载子节点
        private void treeView1_AfterExpand(object sender, TreeViewEventArgs e)
        {
            TreeNode parentNode = e.Node;
            // parentNode.Nodes.RemoveByKey("emptyNode");//移除空节点
            parentNode.Nodes.Clear();
            string path = parentNode.Tag.ToString();            if (Directory.Exists(path))
            {
                DirectoryInfo dir = new DirectoryInfo(path);                FileSystemInfo[] files = dir.GetFileSystemInfos();
                foreach (FileSystemInfo f in files)
                {
                    TreeNode node = new TreeNode();
                    node.Text = f.Name;
                    node.Tag = f.FullName;
                    parentNode.Nodes.Add(node);  //加载子节点                    if (Directory.Exists(node.Tag.ToString()))
                    {
                        DirectoryInfo subDir = new DirectoryInfo(node.Tag.ToString());
                        if (subDir.Attributes != (FileAttributes.System | FileAttributes.Hidden | FileAttributes.Directory))
                        {
                            FileSystemInfo[] subFiles = null;
                            try
                            {
                                subFiles = subDir.GetFileSystemInfos();
                            }
                            catch { continue; }
                            if (subFiles.Length > 0)   //有子节点，先添加一个空节点
                            {
                                node.Nodes.Add("emptyNode", string.Empty);
                            }
                        }
                    }
                }            }
        }目录树形结构显示。路径知道了打开文件就不用说了哈
