Exemplos
The following subroutine, given a CellSet and the total number of cells for which information should be displayed, iterates through the Tuples collection and displays information for each tuple:
Public Sub ListTupleCollection(ByRef AxisToCheck As Axis, _
Optional ByVal Count As Integer = 10)
' Because a Set object can represent thousands of tuples,
' the Count parameter limits the output to a
' specified number of cells.
' Check the parameter before performing actions on it.
If AxisToCheck Is Nothing Then
Throw New System.ArgumentNullException("AxisToCheck")
Else
' Iterate through the Tuples collection of the
' Set object.
Try
Dim tupleToCheck As Tuple
Dim tupleCount As Integer
Dim tupleIndex As Integer
tupleCount = AxisToCheck.Set.Tuples.Count
Debug.WriteLine("Found " & tupleCount & _
" tuple(s) in axis:")
If tupleCount > Count Then tupleCount = Count
If tupleCount > 0 Then
For tupleIndex = 0 To tupleCount
tupleToCheck = AxisToCheck.Set.Tuples(tupleIndex)
Debug.WriteLine("Tuple: " & _
tupleToCheck.TupleOrdinal)
Debug.WriteLine(" No. of members: " & _
tupleToCheck.Members.Count)
