示例1: Main
' 导入命名空间
Imports System.Collections
Imports System.Collections.Generic
Public Class ScoreComparer(Of T1, T2) : Implements IComparer
Public Function Compare(x As Object, y As Object) As Integer _
Implements IComparer.Compare
Dim tX As Tuple(Of T1, T2) = TryCast(x, Tuple(Of T1, T2))
If tX Is Nothing Then
Return 0
Else
Dim tY As Tuple(Of T1, T2) = DirectCast(y, Tuple(Of T1, T2))
Return Comparer(Of T2).Default.Compare(tx.Item2, tY.Item2)
End If

Module Example
Public Sub Main()
Dim scores() As Tuple(Of String, Nullable(Of Integer)) =
{ New Tuple(Of String, Nullable(Of Integer))("Jack", 78),
New Tuple(Of String, Nullable(Of Integer))("Abbey", 92),
New Tuple(Of String, Nullable(Of Integer))("Dave", 88),
New Tuple(Of String, Nullable(Of Integer))("Sam", 91),
New Tuple(Of String, Nullable(Of Integer))("Ed", Nothing),
New Tuple(Of String, Nullable(Of Integer))("Penelope", 82),
New Tuple(Of String, Nullable(Of Integer))("Linda", 99),
New Tuple(Of String, Nullable(Of Integer))("Judith", 84) }
Console.WriteLine("The values in unsorted order:")
For Each score In scores
Console.WriteLine(score.ToString())
Next
Console.WriteLine()
Array.Sort(scores, New ScoreComparer(Of String, Nullable(Of Integer))())
Console.WriteLine("The values in sorted order:")
For Each score In scores
Console.WriteLine(score.ToString())
Next
End Sub
End Module输出：
The values in unsorted order: (Jack, 78) (Abbey, 92) (Dave, 88) (Sam, 91) (Ed, ) (Penelope, 82) (Linda, 99) (Judith, 84) The values in sorted order: (Ed, ) (Jack, 78) (Penelope, 82) (Judith, 84) (Dave, 88) (Sam, 91) (Abbey, 92) (Linda, 99)
