Private Function GetPageTitleBasedOnSiteNavigation() As String
If SiteMap.CurrentNode Is Nothing Then
Throw New ArgumentException("currentNode cannot be Nothing")
End If
'We are visiting a page defined in the site map - build up the page title
'based on the site map node's place in the hierarchy
Dim output As String = String.Empty
Dim currentNode As SiteMapNode = SiteMap.CurrentNode
While currentNode IsNot Nothing
If output.Length > 0 Then
output = currentNode.Title & " :: " & output

在上面的代码中，首先预定义了两个常量，然后逐步建立sitemap的结点，一开始结点是null的，然后再调用GetPageTitleBasedOnSiteNavigation() 这个过程，在每建立一个sitemap的结点时，用字符串进行连接，最后返回给page.title即可实现，当然也可以用递归实现。
