AxisCollection 类型公开以下成员。
属性
名称 | 说明 | |
---|---|---|
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. |

注释
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.
注意 |
---|
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. |
示例
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
Catch ex As AdomdConnectionException
' The connection could not be opened or was disconnected.
' This error can occur at any time, if the provider is
' disconnected from the server.
Debug.WriteLine(ex)
Throw ex
Catch ex As AdomdErrorResponseException
' A response is received from a provider which indicates an error.
Debug.WriteLine(ex)
Throw ex
Catch ex As AdomdUnknownResponseException
' A response has been returned from the provider that
' was not understood.
Debug.WriteLine(ex)
Throw ex
Catch ex As AdomdCacheExpiredException
' A cached version of an ADOMD.NET object is no longer valid.
' This error is typically raised when reviewing meta data.
Debug.WriteLine(ex)
Throw ex
Catch ex As AdomdException
' Any other error raised by ADOMD.NET.
Debug.WriteLine(ex)
Throw ex
Catch ex As Exception
' Any other error.
Debug.WriteLine(ex)
Throw ex

End If
End Sub
