Свойства
Имя | Описание | |
---|---|---|
Count | Gets the number of Axis objects in the collection. | |
IsSynchronized | Gets a value indicating whether access to the collection is synchronized (thread safe). | |
Item[Int32] | Gets the specified Axis from the AxisCollection collection by its index. In Microsoft Visual C#, this property is the indexer for the AxisCollection class. | |
Item[String] | Gets the specified Axis from the AxisCollection collection by its name. In Microsoft Visual C#, this property is the indexer for the AxisCollection class. | |
SyncRoot | Gets an object that can be used to synchronize access to the AxisCollection collection. |

Замечания
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.
Примечание |
---|
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. |
Примеры
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)
Next

Throw ex

Debug.WriteLine(ex)

Catch ex As AdomdUnknownResponseException
' A response has been returned from the provider that

Debug.WriteLine(ex)
