Hinweise
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.
Beispiele
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

Threadsicherheit
Alle öffentlichen static (Shared in Visual Basic) Member dieses Typs sind threadsicher. Bei Instanzmembern ist die Threadsicherheit nicht gewährleistet.
