How do I find out the page type of a PageNode? (Composite C1)

Question

I want to build an ASP.NET usercontrol that shows a homepage navigation including only pages of a certain page type (which I named ContentPage).

In the database table for published pages this information is present for each page (Column PageTypeID) but I am unable to find any way to access it via the Composite API from my code.

using(var conn = new DataConnection())
{
    var siteMapNav = new SitemapNavigator(conn);
    var pages = siteMapNav.CurrentHomePageNode.GetPageNodes(SitemapScope.DescendantsAndCurrent);
    // what now?
}

How can I access the PageType information for a page from C#?

You can use the data connection to look up the page type on IPage.PageTypeId and then combine the the result from SitemapNavigator:

using (var conn = new DataConnection())
{
    Guid pageTypeIdInQuestion = Guid.Empty; // put type id here

    var siteMapNav = new SitemapNavigator(conn);
    var pagesOfDesiredType = conn.Get<IPage>().Where(f => f.PageTypeId == pageTypeIdInQuestion).Select(f => f.Id);
    var pages = siteMapNav.CurrentHomePageNode.GetPageNodes(SitemapScope.DescendantsAndCurrent).Where(f=> pagesOfDesiredType.Contains(f.Id));
}

Consider caching the result you get here and flush it with add/update/delete events on IPage and IPageStructure.
