SPNavigationNode class

Represents a node in a hierarchical navigation structure for a Microsoft SharePoint Foundation Web site.

System.Object
  Microsoft.SharePoint.Navigation.SPNavigationNode

Namespace:  Microsoft.SharePoint.Navigation
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

[PermissionSetAttribute(SecurityAction.Assert, Name = "FullTrust")]
public sealed class SPNavigationNode

Unlike the SPNavigationNodeCollection class, the SPNavigationNode class requires you to call the Update method to cause property changes to existing nodes to be saved to the database. However moves occur immediately.

The following console application prints a simple map of the navigation structure for a Web site.

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Navigation;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            using (SPSite site = new SPSite("http://localhost"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    string format = "|-{0} (Id = {1})";

                    foreach (SPNavigationNode globalNode in web.Navigation.GlobalNodes)
                    {
                        Console.WriteLine(format, globalNode.Title, globalNode.Id);

                        foreach (SPNavigationNode childNode in globalNode.Children)
                        {
                            Console.WriteLine("  " + format, childNode.Title, childNode.Id);
                        }
                        Console.WriteLine("|");
                    }
                }
            }
            Console.Write("\nPress ENTER to continue....");
            Console.ReadLine();
        }
    }
}
