Get IIS sites and virtual directories with .NET / C# / Directory Services

public List GetSites(string serverName)        {             List Nodes = new List();             CustomTreeNode tnResult = new CustomTreeNode();             try             {                 DirectoryEntry w3svc = new DirectoryEntry("IIS://" + serverName + "/w3svc");                 foreach (DirectoryEntry entry in w3svc.Children)                 {                    if (entry.SchemaClassName == "IIsWebServer")                    {                         CustomTreeNode Site = new CustomTreeNode(entry.Properties["ServerComment"].Value.ToString());                         this.ServerLoadStart(entry.Properties["ServerComment"].Value.ToString());

/>                        Site.CurrentEntry = entry;
                        Site.ImageIndex = 1;
                        Site.SelectedImageIndex = 1;
                        Site = GetVirtualDirectories(entry, Site);
                        Site.ImageIndex = 0;
                        Site.SelectedImageIndex = 0;
                        Nodes.Add(Site);
                   }
                }
            }
            catch (Exception ex)
            {
                string msg = ex.Message;
            }
            return Nodes;
       }
       private CustomTreeNode GetVirtualDirectories(DirectoryEntry site, CustomTreeNode Parent)
       {
            string VirDirSchemaName = "IIsWebVirtualDir";
            DirectoryEntry folderRoot = site.Children.Find("Root", VirDirSchemaName);
            foreach (DirectoryEntry deChild in folderRoot.Children)
            {
                CustomTreeNode tnFolder = new CustomTreeNode(deChild.Name);
                this.VirtualDirectoryStart(deChild.Name);
                tnFolder.ImageIndex = 0;
                tnFolder.SelectedImageIndex = 0;
                tnFolder.CurrentEntry = deChild;
                tnFolder.ImageIndex = 1;
                tnFolder.SelectedImageIndex = 1;
                Parent.Nodes.Add(tnFolder);
            }
            return Parent;
       }

Here is the result I get after few more hours of work:
