当我得到一个列表框的文本时，我写

ListBox1.Items(2).ToString()

允许我这样做的代码是什么？

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

Answer 1

它被称为“索引属性”：

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
