Examples
The following console application creates a link to a subsite on the Quick Launch menu for the parent Web site.
using System;
using System.Linq;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Navigation;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
using (SPSite site = new SPSite("https://localhost"))
{
using (SPWeb web = site.OpenWeb("subsite"))
{
// Make sure the Web site is not the root.
if (!web.IsRootWeb)
{
// Get the display text and URL for a link.
string title = web.Title;
string url = web.ServerRelativeUrl;
// Get the Sites heading on the parent's Quick Launch.
SPNavigationNode sitesHeading = web.ParentWeb.Navigation.GetNodeById((int)SPQuickLaunchHeading.Sites);
SPNavigationNode webNode = null;
if (sitesHeading != null)
{
// Check for an existing link to the current Web site.
webNode = sitesHeading
.Children
.Cast<SPNavigationNode>()
.FirstOrDefault(n => n.Url == url);
}
// No link, so create one.
if (webNode == null)
{
// Create the node.
webNode = new SPNavigationNode(title, url);
// Add it to the parent web's quick launch.
webNode = web.ParentWeb.Navigation.AddToQuickLaunch(webNode, SPQuickLaunchHeading.Sites);
}
string format = "Quick Launch for {0} has a link to {1} at {2}";
Console.WriteLine(format, webNode.Navigation.Web.Title, webNode.Title, webNode.Url);
}
