VB.NET ArrayList 到 List(Of T) 类型的复制/转换 [英] VB.NET ArrayList to List(Of T) typed copy/conversion

问题描述

我有一个返回旧式 ArrayList 的第 3 方方法，我想将其转换为类型化的 ArrayList(Of MyType).

I have a 3rd party method that returns an old-style ArrayList, and I want to convert it into a typed ArrayList(Of MyType).

Dim udc As ArrayList = ThirdPartyClass.GetValues()
Dim udcT AS List(Of MyType) = ??

我做了一个简单的循环，但一定有更好的方法:

I have made a simple loop, but there must be a better way:

Dim udcT As New List(Of MyType)
While udc.GetEnumerator.MoveNext
    Dim e As MyType = DirectCast(udc.GetEnumerator.Current, MyType)
    udcT.Add(e)
End While

推荐答案

Dim StronglyTypedList = OriginalArrayList.Cast(Of MyType)().ToList()
' requires `Imports System.Linq`
