示例1: fruits
' Create an array of strings.
Dim fruits() As String =
{"apple", "banana", "mango", "orange", "passionfruit", "grape"}
' Project each item in the array to an anonymous type
' that stores the item's index in the array and
' a substring of each item whose length is equal
' to the index position in the original array.
Dim query =
fruits.Select(Function(fruit, index) _
New With {index, .Str = fruit.Substring(0, index)})
Dim output As New System.Text.StringBuilder
For Each obj In query
output.AppendLine(obj.ToString())
Next
' Display the output.
Console.WriteLine(output.ToString())輸出：
{ index = 0, Str = }
{ index = 1, Str = b }
{ index = 2, Str = ma }
{ index = 3, Str = ora }
{ index = 4, Str = pass }
{ index = 5, Str = grape }
示例2: IEnumerable
' Create a collection of sequential integers
' from 1 to 10 and project their squares.
Dim squares As IEnumerable(Of Integer) =

Dim output As New System.Text.StringBuilder
For Each num As Integer In squares
output.AppendLine(num)
Next
' Display the output.
Console.WriteLine(output.ToString())輸出：
