TupleCollection 型別公開下列成員。

屬性

	名稱	說明
	Count	Gets the number of Tuple objects in the collection.
	IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread safe).
	Item	Gets the specified Tuple from the collection by its index. In C#, this property is the indexer for the TupleCollection class.
	SyncRoot	Gets a System.Object that can be used to synchronize access to the collection.

	CopyTo	Copies the elements of the collection to the specified array.
	Equals	(繼承自 Object。)
	GetEnumerator	Gets an Enumerator for iterating through the collection.
	GetHashCode	(繼承自 Object。)
	GetType	(繼承自 Object。)
	ToString	(繼承自 Object。)

範例

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)
                Next
            End If
        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
        End Try
    End If
End Sub
