Module Example
Sub Main()
Dim doubleTuple1 = Tuple.Create(12.3455)
Dim doubleTuple2 = Tuple.Create(16.8912)
Dim doubleTuple3 = Tuple.Create(12.3455)
Dim singleTuple1 = Tuple.Create(CSng(12.3455))
Dim tuple2 = Tuple.Create("James", 97.3)
' Compare first tuple with a Tuple(Of Double) with a different value.
TestEquality(doubleTuple1, doubleTuple2)
' Compare first tuple with a Tuple(Of Double) with the same value.
TestEquality(doubleTuple1, doubleTuple3)
' Compare first tuple with a Tuple(Of Single) with the same value.
TestEquality(doubleTuple1, singleTuple1)
' Compare a 1-tuple with a 2-tuple.
TestEquality(doubleTuple1, tuple2)
End Sub
Private Sub TestEquality(tuple As Tuple(Of Double), obj As Object)
Try
Console.WriteLine("{0} = {1}: {2}", tuple.ToString(),
obj.ToString,
tuple.Equals(obj))
Catch e As ArgumentException
If obj.GetType.IsGenericType Then
If obj.GetType().Name = "Tuple`1" Then
Console.WriteLine("Cannot compare a Tuple(Of {0}) with a Tuple(Of {1}).",
tuple.Item1.GetType().Name, obj.Item1.GetType().Name)
Else
Console.WriteLine("Cannot compare a {0} with a {1}.", tuple.GetType().Name,

End If
