推荐答案

出了什么问题?你在哪里困?

试试类似的东西:

What is the problem? Where are you stuck?

Try something like:

For x As Integer = 0 to buttonCount - 1
   Dim newButton as Button

   newButton = New Button()
   With newButton
      .Name = "Category" & x.ToString & "Button"
      .Text = "Category " & x.ToString
      AddHandler newButton.Click, AddressOf myButtonClickEvent
      ''You will need to position the buttons as well...
      Form1.Controls.Add(newButton)
   End With

Next x

并创建事件处理程序以拦截您的按钮单击事件:

And create the eventhandler to intercept your button click events:

Public Sub myButtonClickEvent(Byval Sender as Object, Byval e as System.EventArgs)
    MsgBox DirectCast(sender, Button).Name & " Clicked"
End Sub

所有这些都写在我的头上，所以您可能需要做一些调整...

All this written off the top of my head, so you will probably need to do a few adjustments...
