UserControl + ArrayList + vb.net

Question

當我得到列表框的文本時，我會寫

ListBox1.Items(2).ToString()

允許我執行此操作的代碼是什么？

UserControl.positioniwant(2).title
UserControl.positioniwant(1).msg

Answer 1

它稱為“索引屬性”：

Public Class Foo 

    Public Property Position(ByVal index As Integer) As String
        Get
            Return _position(index)
        End Get
        Set(ByVal Value As String)
            _position(index) = Value
        End Set
    End Property
    Private _position(9) As String

End Class
