Return Value

Type: System.String
The string representation of this Tuple(Of T1, T2, T3, T4, T5, T6, T7, TRest) object.

The string returned by this method takes the form (Item1, Item2, Item3, Item4, Item5, Item6, Item7, Item8…), where Item1, Item2, Item3, Item4, Item5, Item6, and Item7 represent the values of the Item1, Item2, Item3, Item4, Item5, Item6, and Item7 properties. Item8 represents the value of the Tuple(Of T1, T2, T3, T4, T5, T6, T7, TRest) object's Next.Item1 property. The value of any additional nested components follow Item8. If any of the property values is Nothing, it is represented as String.Empty.

The following example creates a 17-tuple that contains population data for the city of Detroit, Michigan, from 1860 to 1900. It then uses the ToString method to display the tuple's data.

Module Example
    Sub Main()
        Dim from1980 As Tuple(Of Integer, Integer, Integer) =
            Tuple.Create(1203339, 1027974, 951270)
        Dim from1910 As New Tuple(Of Integer, Integer, Integer, Integer, Integer, Integer, Integer, _
            Tuple(Of Integer, Integer, Integer)) _
            (465766, 993078, 1568622, 1623452, 1849568, 1670144, 1511462, from1980)
        Dim population As New Tuple(Of String, Integer, Integer, Integer, Integer, Integer, Integer, _ 
            Tuple(Of Integer, Integer, Integer, Integer, Integer, Integer, Integer, Tuple(Of Integer, Integer, Integer))) _
            ("Detroit", 1860, 45619, 79577, 116340, 205876, 285704, from1910)

        Console.WriteLine(population.ToString())      
    End Sub 
End Module
