一个关于自定义控件的问题

VB code

Public Class listbox    Inherits System.Windows.Forms.UserControl    Public str_VenuesName As String    Public str_VenuesNo As String    Public arrListItems As New ArrayList    Public str_BookTime() As String    Private m_textcolor As Color = System.Drawing.Color.Black '字体颜色    Private Sub listbox_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load        Me.Label1.Text = str_VenuesNo & str_VenuesName            Dim b As Integer        Dim s As String'需要返回的值        Dim c As String'需要返回的值        For b = arrListItems.Count - 1 To 0 Step -1            s = arrListItems.Item(b).ToString().Remove(arrListItems.Item(b).ToString().Length - 1, 1)            c = arrListItems.Item(b).ToString().Substring(arrListItems.Item(b).ToString().Length - 1, 1)                     MessageBox.Show(s & c)            Me.List.Items.Add(s)        Next  End Sub    Public Sub List_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles List.Click        MessageBox.Show(Me.List.Items(Me.List.SelectedIndex))    End SubEnd Class

我自定义了一个控件 包含1个listbox和一个label，向里面传了一个arraylist来写listbox的item，点击后需要返回2个字符串 “S”和“C” 以供我来操作
因为控件是随机自动生成的，所以没法把代码写死，我没想到好的处理方式，请大家帮帮忙，想个办法，只要能把C和S这两个字符串返回到主程序就行了，否则我只有把处理过程写在控件里了

[解决办法]
拟向外公布两个public属性就行了，getter时，取s或c的值
[解决办法]
public string S
{
get{return ...;}
}

public string C
{
get{return ...;}
}
[解决办法]

Public WithEvents list As System.Windows.Forms.ListBox

然后在主程序直接引用
