The SiteMapNodeCollection has a fixed size.

You can test whether a SiteMapNodeCollection collection is read-only by checking the IsReadOnly property.

The Remove method determines equality by calling the Object.Equals method.

The following code example demonstrates how to use the Remove method to remove a SiteMapNode object from a SiteMapNodeCollection collection, and then append the SiteMapNode object to the end of the SiteMapNodeCollection using the Add method. If the SiteMapNodeCollection is read-only, a NotSupportedException exception is caught.

// 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>");

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

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