You can use the Item indexer to iterate over the contents of a SiteMapNodeCollection collection or to replace the SiteMapNode object at a specified index.

The following code example demonstrates how to use the Item indexer to retrieve a SiteMapNode object from the SiteMapNodeCollection collection. In this example, a SiteMapNode object is removed from its position at the second element of the internal array using the Remove method and is appended to the array with the Add method. To insert a SiteMapNode object at a specific index, instead of appending it to the end of the array, use the Insert method.

// Move a node from one spot in the list to another. 
try {
    Response.Write("Original node order: <BR>");
    foreach (SiteMapNode node in nodes) {
        Response.Write( node.Title + "<BR>");
    }
    SiteMapNode aNode = nodes[1];

    Response.Write("Adding " + aNode.Title + " to the end of the collection.<BR>");
    nodes.Add(aNode);

    Response.Write("Removing " + aNode.Title + " at position 1. <BR>");
    nodes.Remove(nodes[1]);

    Response.Write("New node order: <BR>");
    foreach (SiteMapNode node in nodes) {
        Response.Write( node.Title + "<BR>");
    }
}
catch (NotSupportedException nse) {
    Response.Write("NotSupportedException caught.<BR>");
}
