示例1: names1
' Create three string arrays.
Dim names1() As String =
{"Hartono, Tommy"}
Dim names2() As String =
{"Adams, Terry", "Andersen, Henriette Thaulow", "Hedlund, Magnus", "Ito, Shu"}
Dim names3() As String =
{"Solanki, Ajay", "Hoeing, Helge", "Andersen, Henriette Thaulow", "Potra, Cristina", "Iallo, Lucio"}
' Create a List that contains 3 elements, where
' each element is an array of strings.
Dim namesList As New List(Of String())(New String()() {names1, names2, names3})
' Select arrays that have four or more elements and union
' them into one collection, using Empty() to generate the
' empty collection for the seed value.
Dim allNames As IEnumerable(Of String) =
namesList.Aggregate(Enumerable.Empty(Of String)(),
Function(current, nextOne) _
IIf(nextOne.Length > 3, current.Union(nextOne), current))
Dim output As New System.Text.StringBuilder
For Each name As String In allNames
output.AppendLine(name)
Next
' Display the output.
Console.WriteLine(output.ToString())輸出：
Adams, Terry Andersen, Henriette Thaulow Hedlund, Magnus Ito, Shu Solanki, Ajay Hoeing, Helge Potra, Cristina Iallo, Lucio
