示例1: GetCats
Structure Pet
Public Name As String
Public Age As Integer
End Structure
' Returns an array of Pet objects.
Function GetCats() As Pet()
Dim cats() As Pet = {New Pet With {.Name = "Barley", .Age = 8},
New Pet With {.Name = "Boots", .Age = 4},
New Pet With {.Name = "Whiskers", .Age = 1}}
Return cats
End Function
' Returns an array of Pet objects.
Function GetDogs() As Pet()
Dim dogs() As Pet = {New Pet With {.Name = "Bounder", .Age = 3},
New Pet With {.Name = "Snoopy", .Age = 14},
New Pet With {.Name = "Fido", .Age = 9}}
Return dogs
End Function
Sub ConcatEx1()
' Create two arrays of Pet objects.
Dim cats() As Pet = GetCats()
Dim dogs() As Pet = GetDogs()
' Project the Name of each cat and concatenate
' the collection of cat name strings with a collection
' of dog name strings.
Dim query As IEnumerable(Of String) =
cats _
.Select(Function(cat) cat.Name) _
.Concat(dogs.Select(Function(dog) dog.Name))
Dim output As New System.Text.StringBuilder
For Each name As String In query
output.AppendLine(name)
Next
' Display the output.
Console.WriteLine(output.ToString())
End Sub輸出：
Barley Boots Whiskers Bounder Snoopy Fido
示例2: cats
' Create two arrays of Pet objects.
Dim cats() As Pet = GetCats()
Dim dogs() As Pet = GetDogs()
' Create an IEnumerable collection that contains two elements.
' Each element is an array of Pet objects.
Dim animals() As IEnumerable(Of Pet) = {cats, dogs}
Dim query As IEnumerable(Of String) =
(animals.SelectMany(Function(pets) _
pets.Select(Function(pet) pet.Name)))
Dim output As New System.Text.StringBuilder
For Each name As String In query
output.AppendLine(name)
Next
' Display the output.
Console.WriteLine(output.ToString())
' This code produces the following output:
'
' Barley
' Boots
' Whiskers
' Bounder
