Type: System.Web.SiteMapNode

A SiteMapNode to add to the SiteMapNodeCollection.


value is null.

Use the SiteMapNodeCollection constructor to create a SiteMapNodeCollection collection with a single initial SiteMapNode object. You can add elements to the SiteMapNodeCollection using the Add, AddRange, or Insert method.

The following code example demonstrates how to create a SiteMapNodeCollection collection with a single initial SiteMapNode object, and then add a SiteMapNodeCollection of SiteMapNode objects to it using the AddRange method. You can modify the SiteMapNodeCollection, even though the individual SiteMapNode objects might be read-only.

// Create a SiteMapNodeCollection with all the nodes
// from the first two hierarchical levels of the current
// site map.
SiteMapNodeCollection baseCollection =
    new SiteMapNodeCollection(SiteMap.RootNode);

SiteMapNodeCollection childCollection =


Response.Write( "<BR>Derived SiteMapNodeCollection.<BR><HR><BR>");
foreach (SiteMapNode node in baseCollection) {
    Response.Write( node.Title + "<BR>");
