Exemplos

The following subroutine, given a CellSet and the total number of cells for which information should be displayed, iterates through the Tuples collection and displays information for each tuple:

Public Sub ListTupleCollection(ByRef AxisToCheck As Axis, _
    Optional ByVal Count As Integer = 10)

    ' Because a Set object can represent thousands of tuples,
    ' the Count parameter limits the output to a 
    ' specified number of cells.

    ' Check the parameter before performing actions on it.
    If AxisToCheck Is Nothing Then
        Throw New System.ArgumentNullException("AxisToCheck")
    Else
        ' Iterate through the Tuples collection of the
        ' Set object. 
        Try
            Dim tupleToCheck As Tuple
            Dim tupleCount As Integer
            Dim tupleIndex As Integer

            tupleCount = AxisToCheck.Set.Tuples.Count

            Debug.WriteLine("Found " & tupleCount & _
                " tuple(s) in axis:")

            If tupleCount > Count Then tupleCount = Count
            If tupleCount > 0 Then
                For tupleIndex = 0 To tupleCount
                    tupleToCheck = AxisToCheck.Set.Tuples(tupleIndex)
                    Debug.WriteLine("Tuple: " & _
                        tupleToCheck.TupleOrdinal)
                    Debug.WriteLine("  No. of members:    " & _
                        tupleToCheck.Members.Count)

            Throw ex
        Catch ex As AdomdErrorResponseException
            ' A response is received from a provider which indicates an error.

            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            ' A cached version of an ADOMD.NET object is no longer valid.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.
