Public Class Example
Public Shared Sub Main()
Dim dinosaurs As New List(Of String)

Console.WriteLine(vbLf & "Insert into the wrapped List:")
Console.WriteLine("Insert(2, ""Oviraptor"")")
dinosaurs.Insert(2, "Oviraptor")
Console.WriteLine()
For Each dinosaur As String In readOnlyDinosaurs
Console.WriteLine(dinosaur)
Next
Dim dinoArray(readOnlyDinosaurs.Count + 1) As String
readOnlyDinosaurs.CopyTo(dinoArray, 1)
Console.WriteLine(vbLf & "Copied array has {0} elements:", _

End Class输出：
Tyrannosaurus
Amargasaurus
Deinonychus
Compsognathus
Count: 4
Contains("Deinonychus"): True
readOnlyDinosaurs(3): Compsognathus
IndexOf("Compsognathus"): 3
Insert into the wrapped List:
Insert(2, "Oviraptor")
Tyrannosaurus
Amargasaurus
Oviraptor
Deinonychus
Compsognathus
Copied array has 7 elements:
""
"Tyrannosaurus"
"Amargasaurus"
"Oviraptor"
"Deinonychus"
