Propriedades

	Nome	Descrição
	Count	Gets the number of CubeDef objects in the collection.
	IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread safe).

Exemplos

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)
            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 metadata.
            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
