Dynamically creating quick launch header & link in Sharepoint

The following code can be used to create a header in Sharepoint quick launch programmatically. It also adds a new link to the quick launch

 string link = System.Configuration.ConfigurationSettings.AppSettings["link"];

string HeaderlinkTitle = System.Configuration.ConfigurationSettings.AppSettings["HeaderLinkTitle"];
string SublinkTitle = System.Configuration.ConfigurationSettings.AppSettings["SubLinkTitle"];
string SitecollectionURL = System.Configuration.ConfigurationSettings.AppSettings["SitecollectionURL"];

using (SPSite site = new SPSite(SitecollectionURL))

{

SPWeb web = site.OpenWeb();
foreach (SPWeb subweb in site.AllWebs)
{

SPNavigationNodeCollection quickLaunchNodes = subweb.Navigation.QuickLaunch;
bool LinkisThere = false;
for (int i = 0; i <= quickLaunchNodes.Count-1; i++)

{
if (quickLaunchNodes[i].Title == HeaderlinkTitle)
{
LinkisThere = true;
int InitialChildrenCount = quickLaunchNodes[i].Children.Count;
bool ChildrenLinkisThere = false;
for (int j = 0; j < InitialChildrenCount; j++)
{
if (quickLaunchNodes[i].Children[j].Title == SublinkTitle)

{

ChildrenLinkisThere = true;

quickLaunchNodes[i].Children[j].Delete();

SPNavigationNode subMenuItem = new SPNavigationNode(SublinkTitle, link, true);

quickLaunchNodes[i].Children.AddAsFirst(subMenuItem);

break;

}

}

if (InitialChildrenCount == 0

ChildrenLinkisThere == false)

{

SPNavigationNode subMenuItem = new SPNavigationNode(SublinkTitle, link, true);

quickLaunchNodes[i].Children.AddAsFirst(subMenuItem);

}

break;

}

}

if (LinkisThere == false)

{

SPNavigationNode menuItem = new SPNavigationNode(HeaderlinkTitle, link, true);

quickLaunchNodes.AddAsLast(menuItem);

SPNavigationNode subMenuItem = new SPNavigationNode(SublinkTitle, link, true);

quickLaunchNodes[quickLaunchNodes.Count-1].Children.AddAsFirst(subMenuItem);

}

}

Console.WriteLine("Successfull");
Console.Read();
