Adding a new navigation node to sharepoint 2010 To

问题:

I am trying to add a new navigation node to Top Navigation bar in my sharepoint website and I am using the following code:

public void AddNavigation(SPWeb web, String url, string module, string key)
{
    var resourceFile = "$Resources:" + module + "," + key;
    UnregisterGlobalNavigationLink(web, url);
    SPNavigationNode node = web.Navigation.GetNodeByUrl(url);
    if (node != null && overrideGlobalNavigationSetting) return node;
    node = new SPNavigationNode(resourceFile, url);
    node = web.Navigation.TopNavigationBar.AddAsLast(node);**//Exception here**
} 

But I am getting an exception that I don't know how to resolve:

An unexpected error occured while manipulating the navigational structure of this Web.

How can I solve this issue?

回答1:

If it is an external node you want to add a another parameter isExternal = true to the node constructor, so it looks like this:

node = new SPNavigationNode(resourceFile, url, true);

EDIT: And by external I mean it points outside the site collection
