用asp.net实现九连环小游戏

呵呵，培训时老师讲的简单例子，俺自己作了一下，还可以运行。  public Class ChinaRing1
    Inherits System.Web.UI.Page   #Region " Web 窗体设计器生成的代码 "    '该调用是 Web 窗体设计器所必需的。
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()    End Sub
    Protected WithEvents ChinaRingCkBox1 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox2 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox3 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox4 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox5 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox6 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox7 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox8 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingCkBox9 As System.Web.UI.WebControls.CheckBox
    Protected WithEvents ChinaRingLb1 As System.Web.UI.WebControls.Label
    Protected ChinaRingCkBox(8) As System.Web.UI.WebControls.CheckBox
    '注意: 以下占位符声明是 Web 窗体设计器所必需的。

        'CODEGEN: 此方法调用是 Web 窗体设计器所必需的
        '不要使用代码编辑器修改它。
        InitializeComponent()
    End Sub  #End RegionPrivate Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ChinaRingCkBox(0) = ChinaRingCkBox1
        ChinaRingCkBox(1) = ChinaRingCkBox2
        ChinaRingCkBox(2) = ChinaRingCkBox3
        ChinaRingCkBox(3) = ChinaRingCkBox4
        ChinaRingCkBox(4) = ChinaRingCkBox5
