Using SharePoint Feature Receiver create Virtual Directory in IIS

As per my previous post you create virtual directory from command line.
Here another way to create virtual directory in IIS site.
Everything is possible programmatically.
I created one SharePoint Feature to create virtual directory in IIS’s SharePoint site.

string _serverName = string.Empty;
        string _userName = string.Empty;
        string _password = string.Empty;
        string _webSiteName = string.Empty;
        string _physicalPath = string.Empty;

        public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            try
            {
                SPWeb tempweb;
                SPSite tempsite;

                if (properties.Feature.Parent is SPWeb)
                {
                    tempweb = properties.Feature.Parent as SPWeb;
                    tempsite = tempweb.Site;
                }
                else
                {
                    tempsite = properties.Feature.Parent as SPSite;
                    tempweb = tempsite.RootWeb;
                }

                GetWebServiceParamFromConfig(tempweb.Url);
                if (!_serverName.Equals(string.Empty) && !_userName.Equals(string.Empty) && !_password.Equals(string.Empty) && !_webSiteName.Equals(string.Empty) && !_physicalPath.Equals(string.Empty))
                {
                    string webSiteId = GetIISWebsiteID(_serverName, _webSiteName);

                    String strRootSubPath = "/W3SVC/" + webSiteId + "/Root";
                    
                    String strSchema = "IIsWebVirtualDir";

                    DirectoryEntry objRootDirectoryEntry = new DirectoryEntry("IIS://" + _serverName + strRootSubPath);
                    objRootDirectoryEntry.Username = _userName;
                    objRootDirectoryEntry.Password = _password;
                    objRootDirectoryEntry.RefreshCache();
                    DirectoryEntry objNewVDir = objRootDirectoryEntry.Children.Add("CustomWebService", strSchema);
                    objNewVDir.Properties["Path"].Insert(0, _physicalPath);
                    objNewVDir.CommitChanges();
                    deRoot.CommitChanges();
                    
                    objNewVDir.Invoke("AppCreate", true);
                    
                    objNewVDir.CommitChanges();
                    objRootDirectoryEntry.CommitChanges();
                    objNewVDir.Close();
                    deRoot.Close();
                }
                else
                {
                    Utility.ErrorLog("During WebService Vir. Dir. Create in IIS - Param. Empty", System.Diagnostics.EventLogEntryType.Error, "CreateWebServiceVirDir - FeatureActivated()");
                }
            }
            catch (Exception ex)
            {

            }
        }

        public void GetWebServiceParamFromConfig(string webUrl)
        {
            DataSet ds = GetDataFromList(webUrl);
            DataTable dtWebServiceParam = ds.Tables["WebService"];

            if (dtWebServiceParam != null && dtWebServiceParam.Rows.Count > 0)

            String webId = "";
            foreach (DirectoryEntry de in w3svc.Children)
            {
                if (de.SchemaClassName == "IIsWebServer" && de.Properties["ServerComment"][0].ToString() == websiteName)
                {
                    webId = de.Name;
                }
            }
            return webId;
        }
        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
