The site map providers that are listed in the Providers collection are those that are specified in the configuration hierarchy to initialize the SiteMap class. Only the default provider (identified by the Provider property) is guaranteed to be used by the SiteMap during initialization; the presence of a provider in the Providers collection means that it was specified in the configuration and was available during initialization.
The following code example demonstrates how to retrieve the Providers collection from the SiteMap class, and then iterate through it.

If you have more than just the default provider configured for your site, you will see each provider displayed. For example, if you are using the sample Microsoft Access provider (see StaticSiteMapProvider), you see the following output:
XmlSiteMapProvider System.Web.XmlSiteMapProvider
AccessSiteMapProvider Samples.AspNet.AccessSiteMapProvider
