Notas
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.
Ejemplos
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
