Osservazioni
The AxisCollection is used by a CellSet to represent the axes returned by a query. Each Axis contained by an AxisCollection represents a set of congruent tuples organized along one or more hierarchies.
[!NOTA]
The filter axis is not contained in this collection. To access the filter axis, you must reference the OlapInfo.AxesInfo.FilterAxes property of the CellSet.
Esempi
The following subroutine, given a CellSet, iterates through the AxisCollection (represented by the Axes property of the CellSet) and displays information for each axis.
Public Sub ListAxes(ByRef cellsetToCheck As CellSet)
' Check the parameter before performing actions on it.
If cellsetToCheck Is Nothing Then
Throw New System.ArgumentNullException("cellsetToCheck")
Else
' Iterate through the axes of the
' CellSet object. The Axes property of the
' CellSet object returns a reference to the
' AxisCollection object.
Try
Dim axisToCheck As Axis
Debug.WriteLine("Found " & cellsetToCheck.Axes.Count & _
" axes in cellset:")
For Each axisToCheck In cellsetToCheck.Axes
Debug.WriteLine(" Name: " & _
axisToCheck.Name)
