Public Overloads Function Equals(x As Object, y As Object) As Boolean _
Implements IEqualityComparer.Equals
' Return true for all values of Item1.
If TypeOf x Is T1 Then
Return True
ElseIf TypeOf x Is T2 Then
Return x.Equals(y)
Else
Return True
End If
End Function

Implements IEqualityComparer.GetHashCode
If TypeOf obj Is T1 Then
Return CType(obj, T1).GetHashCode()
ElseIf TypeOf obj Is T2 Then
Return CType(obj, T2).GetHashCode()
Else

End If
End Function
End Class
Module Example
Public Sub Main()

For ctr As Integer = 0 To scores.Length - 1
Dim score As IStructuralEquatable = scores(ctr)
For ctr2 As Integer = ctr + 1 To scores.Length - 1
Console.WriteLine("{0} = {1}: {2}", score,
