주의

A tuple consists of an ordered collection of members.

A tuple cannot contain more than one member from any single hierarchy.

In ADOMD.NET, a Tuple is used to represent a tuple by encapsulating the collection of Member objects that define the tuple. Tuple objects can be referenced only through the Tuples property of a Set.

예

The following function, given a Tuple, examines the object and returns a Multidimensional Expressions (MDX) string representation of the tuple:

Public Function GetTupleString(ByRef TupleToConvert As Tuple) As String
    If TupleToConvert Is Nothing Then
        Throw New System.ArgumentNullException("TupleToConvert")
    Else
        Dim tupleCount As Integer = TupleToConvert.Members.Count
        Dim tupleIndex As Integer = 0

        If tupleCount = 0 Then
            ' An empty tuple.
            Return "()"
        Else
            ' Iterate through each member in the Members collection,
            ' adding the value of the UniqueName property to a
            ' string.
            ' Because a tuple can represent many members, this
            ' example uses a StringBuilder object to improve
            ' string handling performance.
            Dim tupleString As New _
                System.Text.StringBuilder(15 * tupleCount)

            ' Tuples are framed with parentheses, with each member
            ' within a tuple separated by a comma.
            tupleString.Append("(")
            For tupleIndex = 0 To tupleCount - 1
                tupleString.Append( _
                TupleToConvert.Members(tupleIndex).UniqueName)
                If tupleIndex < (tupleCount - 1) Then
                    tupleString.Append(", ")
                End If
            Next
            tupleString.Append(")")

            Return tupleString.ToString
        End If
    End If
End Function

스레드 보안

이 유형의 모든 공용 static(Visual Basic에서는 Shared) 멤버는 스레드로부터 안전합니다. 인스턴스 멤버는 스레드로부터의 안전성이 보장되지 않습니다.
