Notes
A measure represents the data within a fact table that is being organized and aggregated by the cube.
In ADOMD.NET, the Measure represents the metadata for a measure within a cube. A measure is not explicitly identified in a cellset, because a measure is treated as a member for querying purposes and is represented by a Measure within the Measures collection of a CubeDef.
Exemples
The following subroutine, given a CubeDef, iterates through the Measures collection and displays information for each Measure:
Public Sub ListMeasures(ByRef CubeToCheck As CubeDef)
' Check the parameter before performing actions on it.
If CubeToCheck Is Nothing Then
Throw New System.ArgumentNullException("CubeToCheck")
Else
' Iterate through the Measures collection of the
' CubeDef object.
Try
Dim measureToCheck As Measure
Debug.WriteLine("Found " & CubeToCheck.Measures.Count & _
" measure(s) in cube:")
For Each measureToCheck In CubeToCheck.Measures
Debug.WriteLine("Measure: " & measureToCheck.Name)
Debug.WriteLine(" Caption: " & _
measureToCheck.Caption)
Debug.WriteLine(" Description: " & _
measureToCheck.Description)
