SharePoint: Add Navigation Node using CSOM

Client side object model can update navigation node remotely.  Below is code to add element to top navigation.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using Microsoft.SharePoint.Client;

namespace NavigationCustomAction

{

    class Program

    {

        static void Main(string[] args)

        {

            ClientContext context = new ClientContext("http://goazrapp18:33369");

            Web web = context.Web;

            AddNavigationItem(context, web);

            Console.WriteLine("Please press any key to exit");

            Console.ReadLine();

        }

        private static void AddNavigationItem(ClientContext context, Web web)

        {

            NavigationNodeCreationInformation navigationNodeCreationInformation = new NavigationNodeCreationInformation();

            navigationNodeCreationInformation.Title = "Custom Node";

            navigationNodeCreationInformation.Url = "http://gooogle.com";

            navigationNodeCreationInformation.IsExternal = true;

            navigationNodeCreationInformation.AsLastNode = true;

            web.Navigation.TopNavigationBar.Add(navigationNodeCreationInformation);

            web.Update();

            context.ExecuteQuery();

            Console.WriteLine("Node created Successfully");

        }

    }

}


If you want to add to Quick Launch bar, you have to update one line as below.

web.Navigation.QuickLaunch.Add(navigationNodeCreationInformation);

This will add element at Quick Launch bar as well.
