对不起，很长的一段代码。在我正在设计的游戏中，我的代码从 checkbox.checked if 语句开始，对于每个单击的复选框，当前重复 5 次——每个复选框等于游戏中玩家手中的一张牌。

我想知道的是我能做些什么来让它变得更有活力。即 CardCheckBox1.Checked 对象/方法。如上所述，代码重复了 5 次，因为我有 5 个现有复选框。有没有办法将复选框放入数组或集合中，所以当我单击复选框并点击播放按钮时，它相当于点击 CardCheckBox2.checked = true、CardCheckBox2.checked = true 等。一旦我弄清楚如何为了使该部分动态化，我终于可以开始使其余代码动态化，因为我假设制作动态标签代码的过程与复选框等非常相似。

我有过

Dim CardCheckBoxArray() As CheckBox = {CardCheckBox1, CardCheckBox2, CardCheckBox3, CardCheckBox4, CardCheckBox5}

在模块化级别、Form_Load 过程甚至 Play_Button 过程中发布，但我总是在 CardCheckBox(n).Checked 部分出现空引用异常

If CardCheckBoxArray(0).Checked = True And Player1HandGroup(Number1).QuantityInteger > 0 Then

所以我不知道该去哪里。长一段代码是我的整个 PlayButton_Click 过程，除了其他 CardCheckBox if 语句。

Private Sub PlayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayButton.Click
        Dim n As Integer
        Dim WeaponDiscardInteger As Integer = 1
        AtkPlayerDialog.ShowDialog()
        'Code for choosing which player to attack
        If AtkPlayerDialog.DialogResult = Windows.Forms.DialogResult.Cancel Then
            n = 2
        ElseIf AtkPlayerDialog.DialogResult = Windows.Forms.DialogResult.OK Then
            n = 1
        ElseIf AtkPlayerDialog.DialogResult = Windows.Forms.DialogResult.Abort Then
            n = 3
        ElseIf AtkPlayerDialog.DialogResult = Windows.Forms.DialogResult.Retry Then
            n = 4
        ElseIf AtkPlayerDialog.DialogResult = Windows.Forms.DialogResult.Ignore Then
            n = 5
        End If

'playing card 1
        If CardCheckBox1.Checked = True And Player1HandGroup(Number1).QuantityInteger > 0 Then
            'Subtract Hitpoints when damage is delt
            Player1HandGroup(n).HitPoints -= Player1HandGroup(Number1).DamageInteger
            HitPoints1.Text = Player1HandGroup(1).HitPoints.ToString
            HitPoints2.Text = Player1HandGroup(2).HitPoints.ToString
            HitPoints3.Text = Player1HandGroup(3).HitPoints.ToString
            HitPoints4.Text = Player1HandGroup(4).HitPoints.ToString
            HitPoints5.Text = Player1HandGroup(5).HitPoints.ToString
            'When player plays hand, card quantity is removed from hand to discard pile.
            Player1HandGroup(Number1).QuantityInteger -= 1
            DiscardGroup(Number1).QuantityInteger += 1
            'Shuffle Deck from Discard Pile if Deck is out of cards
            Call DiscardPile()
            'Reset Number Generator, unless weapon isn't discard
            Number = (DeckGroup(Rnd.Next(0, DeckGroup.Count)).ID)
            If DeckGroup(Number).QuantityInteger > 0 Then
                'Grab New Card From Deck
                DeckGroup(Number).QuantityInteger -= 1
                Player1HandGroup(Number).QuantityInteger += 1
                Card1Type = Player1HandGroup(Number).CardType
                CardCheckBox1.Text = Player1HandGroup(Number).CardNameString
                Number1 = Number
            Else
                Call PlayElse()
            End If

如果您在大多数表单代码中/通过大多数表单代码使用复选框数组，则将其从表单加载事件中移出直到表单级别范围。当它在 forn_load 事件子例程内时，与模块级范围不同。

所以你会有......

Dim CardCheckBoxArray() As CheckBox = {CardCheckBox1, CardCheckBox2, CardCheckBox3, CardCheckBox4, CardCheckBox5}


Sub Form_Load(blah blah blah)
  ...
End Sub

Sub Play_Button(blah blah blah)
  ...
End Sub

等等等等
