vb.net按钮数组 vbnet控件数组

VB.net 如何绑定许多button和数组

vb.net里没有像vb那样的控件数组。也就是说复制控件后粘贴没有提示你是否创建控件数组。

你可以试验下面的代码。

Form1.Designer.vb 设计器中的窗体代码如下，上面有六个button。最右边的用来改变前5个地text：

Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated() Partial Class Form1

#Region "Windows フォーム デザイナによって生成されたコード "

System.Diagnostics.DebuggerNonUserCode() Public Sub New()

MyBase.New()

'この呼び出しは、Windows フォーム デザイナで必要です。

InitializeComponent()

End Sub

'Form は、コンポーネント一覧に后処理を実行するために dispose をオーバーライドします。

System.Diagnostics.DebuggerNonUserCode() Protected Overloads Overrides Sub Dispose(ByVal Disposing As Boolean)

If Disposing Then

If Not components Is Nothing Then

components.Dispose()

End If

End If

MyBase.Dispose(Disposing)

End Sub

'Windows フォーム デザイナで必要です。

’==========================================

Form1中的代码如下：

Friend Class Form1

Inherits System.Windows.Forms.Form

Private Sub Command2_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command2.Click

Dim i As Object

'按钮标题数组。

Dim cArr() As String = New String() {"A", "B", "C", "D", "E", "F", "G"}

For i = 0 To Me.Command1.Count - 1

Me.Command1(i).Text = cArr(i)

Next

End Sub

End Class

vb.net窗体上有2个按钮，现在把这2个按钮放在一个按钮数组中，然后用数组名(下标)来调用，出现问题，求解

button1，button2是控件，你在定义的时候就初始化到数组，但是此时控件本身还没有初始化，显然数组得不到正确的值

正确的做法是先定义数组，在对话框load事件中初始化数组，然后再使用

vb.net中定义控件数组，控件数组中加入多个按钮。怎么能在控件数组事件响应对应按钮的事件，代码部分：

Dim bt As New ArrayList

bt.Add(Me.Button5)

bt.Add(Me.Button6)

bt.Add(Me.Button7)

上面这段代码本人表示不懂，故没有使用。下面的代码在VS2015中运行通过：

Private Sub btClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click, Button6.Click, Button7.Click

Select Case CType(sender, Button).Name

Case "Button5"

MessageBox.Show("你点击了 Button5 按钮")

Case "Button6"

MessageBox.Show("你点击了 Button6 按钮")

Case "Button7"

MessageBox.Show("你点击了 Button7 按钮")

End Select

End Sub

vb.net 数组的定义方法

1、点击VS工具。

2、打开后，新建一个Windows窗体应用程序。

3、新建完毕后，如图所示。

4、拖动一个按钮。

5、定义数组最常见的方法，如图示。

6、运行后，点击按钮，弹出提示正常。

7、定义数组第二种方法，属于动态的方法。

8、运行后，点击按钮，数组成功输出。
