Web developers can create and call a method inline based on LINQ expression. For example they can create a function named TestClient() that examines a client an return true or false based on whether they want to include it in the results:
Private Function TestClient(ByVal client As Client) As Boolean
Return client.LastName.StartsWith(“D”)
End Function
Web developers could use the TestClient method like this:
Dim clients As List(Of Client) = New List(Of Client)()
Dim matches = From client In clients
Where TestClient(client)
Select client
