How can I remove nodes from a SiteMapNodeCollection?

Question

I\'ve got a Repeater that lists all the web.sitemap child pages on an ASP.NET page. Its DataSource is a SiteMapNodeCollection. But, I do

Answer 1

I got it to work with code below:

Dim children = From n In SiteMap.CurrentNode.ChildNodes _
               Where CType(n, SiteMapNode).Url <> "/Registration.aspx" _
               Select n
RepeaterSubordinatePages.DataSource = children

Is there a better way where I don't have to use the CType()?

Also, this sets children to a System.Collections.Generic.IEnumerable(Of Object). Is there a good way to get back something more strongly typed like a System.Collections.Generic.IEnumerable(Of System.Web.SiteMapNode) or even better a System.Web.SiteMapNodeCollection?
