Delete all links from quicklaunch?

I would like to delete all the links in a quicklaunch in SP2010 with C#. I tought this will do it, but somehow they are not gonna deleted:

        SPNavigationNodeCollection n = subSite.Navigation.QuickLaunch;
 
         foreach (SPNavigationNode node in n)
         {
             node.Delete();
         }
 

Im able to add links, but not to delete them :/ Any ideas? Thx


Edit: Ah got the fix :)


I cannot write just node.Delete() I need to write n.Delete(node)

Answer:

Try this code:

 SPNavigationNodeCollection nodes = web.Navigation.QuickLaunch;
 for(int i = nodes.Count - 1; i >= 0; i--)
            {
                nodes[i].Delete();
            }
