调用特定的 UserControl 动态创建

Question

我有一组使用以下代码在面板内动态创建的用户控件

Dim X As Integer = 4
Dim Y As Integer = 0

For XRule As Integer = 0 To ArrayRuleNames.Length - 1
    Dim MyRule As New RuleControl
    Dim Location As Point
    Location.X = X
    Location.Y = Y
    With MyRule

        .RuleNameGpb.Text = ArrayRuleNames(XRule)
        .RuleNumberTxt.Text = ArrayRuleNumbers(XRule)
        .RuleNumberTxt.Tag = XRule
        .SendBtn.Text = "Read"
        .Parent = Me
        .Location = Location
        .Visible = True
    End With
    Panel.Controls.Add(MyRule)
    Y += 80
Next

每个用户控件内部都有一些对象，例如 Checkboxes 和 TextBoxes，我需要将 Checked 属性设置为 True o False 并在主 Form(WinForm) 的 Text 属性上写入文本。

所以，我想在上面的代码中定义一个名字，然后用名字来称呼它们，这个概念是正确的还是我应该用不同的方式来做？

给控件起个名字：

With MyRule
  .Name = "MyRule1"
  .RuleNameGpb.Text = ArrayRuleNames(XRule)
  .RuleNumberTxt.Text = ArrayRuleNumbers(XRule)

那么你可以参考它：

If Panel.Controls.ContainsKey("MyRule1") Then
  Dim MyRule As RuleControl = Panel.Controls("MyRule1")
