课堂上有新财产吗？

Question

Well, my question is simple.

I want to add a property to a pre - defined class.

Imports Lidgren.Network

Module Socket
    Public Clients As List(Of NetConnection) = New List(Of NetConnection)

Need to add the "index " property , so that it is " Clients (sender ) .Index "

Answer 1

您使用List(Of T)因此可以访问它的IndexOf方法 -它返回集合中从零开始的位置。

Dim i As Integer = Clients.IndexOf(sender)
