示例1: Example
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) }
Dim number As Integer
Dim mean As Double = ComputeMean(scores, number)
Console.WriteLine("Average test score: {0:N2} (n={1})", mean, number)
End Sub
Private Function ComputeMean(scores() As Tuple(Of String, Nullable(Of Integer)),
ByRef n As Integer) As Double
n = 0
Dim sum As Integer
For Each score In scores
If score.Item2.HasValue Then
n += 1
sum += score.Item2.Value
End If
Next
If n > 0 Then
Return sum / n
Else
Return 0
End If
End Function
End Module输出：
Average test score: 88 (n=7)
