A provider-specific lookup key.

The URL of the page that the node represents within the site.

Exception typeCondition

ArgumentNullException

SiteMapProvider is a null reference (Nothing in Visual Basic).

- or -

key is a null reference (Nothing in Visual Basic).

The XmlSiteMapProvider class, which is the default SiteMapProvider provider implementation for ASP.NET, uses the SiteMapNode.Url property as a lookup key, if one is provided for the node (if a URL is not provided, a tracking identifier is generated for the node). Therefore, any SiteMapNode object that provides a URL and is used by the XmlSiteMapProvider must have a unique URL within the scope of the provider.

The following code example demonstrates how to use the SiteMapNodeCollection constructor to create a new SiteMapNodeCollection collection, and then add elements to it with the Add method.
