示例1: Clump
Dim output As New System.Text.StringBuilder
' A custom class.
Class Clump(Of T)
Inherits List(Of T)
' Constructor.
Public Sub New(ByVal collection As IEnumerable(Of T))
MyBase.New(collection)
End Sub
' Custom implementation of Where().
Function Where(ByVal predicate As Func(Of T, Boolean)) As IEnumerable(Of T)
output.AppendLine("In Clump's implementation of Where().")
Return Enumerable.Where(Me, predicate)
End Function
End Class
Sub AsEnumerableEx1()
' Create a new Clump(Of T) object.
Dim fruitClump As New Clump(Of String)(New String() _
{"apple", "passionfruit", "banana",
"mango", "orange", "blueberry",
"grape", "strawberry"})
' First call to Where():
' Call Clump's Where() method with a predicate.
Dim query1 As IEnumerable(Of String) =
fruitClump.Where(Function(fruit) fruit.Contains("o"))
output.AppendLine("query1 has been created." & vbCrLf)
' Second call to Where():
' First call AsEnumerable() to hide Clump's Where() method and thereby
' force System.Linq.Enumerable's Where() method to be called.
Dim query2 As IEnumerable(Of String) =
fruitClump.AsEnumerable().Where(Function(fruit) fruit.Contains("o"))
output.AppendLine("query2 has been created.")
' Display the output.
Console.WriteLine(output.ToString())
End Sub輸出：
In Clump's implementation of Where(). query1 has been created. query2 has been created.
