This section contains two code examples. The first code example demonstrates how to create a new SiteMapNodeCollection collection and add elements to it. The second code example demonstrates how to add elements to a custom site map provider.
The following code example demonstrates how to use the SiteMapNodeCollection constructor to create a new SiteMapNodeCollection, and then add elements to it with the Add method.
The following code example demonstrates a custom site map provider implementation and shows how to use the SiteMapNodeCollection constructor to create a new SiteMapNodeCollection and add elements to the SiteMapNodeCollection with the Add method.
This code example is part of a larger code example provided for the SiteMapProvider class.
