説明
HierarchyCollection は、外部的には Hierarchy オブジェクトのコレクションを表し、内部的にはコレクションの親に応じて次の 2 つのうちいずれかの方法で読み込まれ、管理されます。
使用例
次のサブルーチンでは、Dimension を受け取り、HierarchyCollection コレクションの繰り返し処理を実行し、各階層の情報を表示します。
Public Overloads Sub ListHierarchies(ByRef DimToCheck As Dimension)
' Check the parameter before performing actions on it.
If DimToCheck Is Nothing Then
Throw New System.ArgumentNullException("DimToCheck")
Else
' Iterate through the Hierarchies collection of the
' Dimension object.
Try
Dim hierToCheck As Hierarchy
Debug.WriteLine("Found " & DimToCheck.Hierarchies.Count & _
" hierarchies in dimension:")
For Each hierToCheck In DimToCheck.Hierarchies
Debug.WriteLine("Hierarchy: " & hierToCheck.Name)
Debug.WriteLine(" Caption: " & _
hierToCheck.Caption)
Debug.WriteLine(" Description: " & _
hierToCheck.Description)
Debug.WriteLine(" UniqueName: " & _
hierToCheck.UniqueName)
