Примеры
The following subroutine, given a connected instance of an AdomdConnection, iterates through the CubeCollection collection and displays various properties:
Public Sub ListCubes(ByRef ConnectionToCheck As AdomdConnection)
' Check the parameter before performing actions on it.
If ConnectionToCheck Is Nothing Then
Throw New System.ArgumentNullException("ConnectionToCheck")
ElseIf ConnectionToCheck.State <> ConnectionState.Open Then
Throw New System.ArgumentException( _
"The specified connection is not open.")
Else
' Iterate through the Cubes collection of the
' AdomdConnection object.
Try
' Note that this example does not provide
' information about the various collections, such as
' NamedSets, provided by the Cube object. Because
' these collections are loaded on demand, you should
' reference them only if you need information
' from them.
Dim cubeToCheck As CubeDef
Debug.WriteLine("Found " & ConnectionToCheck.Cubes.Count & _
" cubes in database:")
For Each cubeToCheck In ConnectionToCheck.Cubes
Debug.WriteLine("Cube: " & cubeToCheck.Name)
Debug.WriteLine(" Caption: " & _
cubeToCheck.Caption)
Debug.WriteLine(" Description: " & _
cubeToCheck.Description)
Debug.WriteLine(" LastProcessed: " & _
cubeToCheck.LastProcessed)

Throw ex
Catch ex As AdomdErrorResponseException
