示例1: PrintFullChildNodeInfo
' Print out the current data node, then iterate through its
' children and do the same.
Private Sub PrintFullChildNodeInfo(ByVal node As IHierarchyData)
Dim whitespace As String = " "
Dim br As String = "<BR>"
Response.Write(Convert.ToString(node) & br)
Response.Write(whitespace & node.Path & br)
' Check for specific types and perform extended functions.
If node.Type = "SiteMapNode" Then
' Because SiteMapNode implements the IHierarchyData interface,
' the IHierarchyData object can be cast directly as a SiteMapNode,
' rather than accessing the Item property for the object that
' the Type property identifies.
Dim siteNode As SiteMapNode = CType(node.Item, SiteMapNode)
Response.Write(whitespace & siteNode.Url & br)
Response.Write(whitespace & siteNode.Description & br)
ElseIf node.Type = "SomeBusinessObject Then" Then
' If the IHierarchyData instance is a wrapper class on a business
' object of some kind, you can retrieve the business object by using
' the IHierarchyData.Item property.
