vb.net如何向SplitContainer1.Panel1中添加button,并按规则排列

您可以使用以下代码向SplitContainer1.Panel1中添加Button，并按照一定的规则排列：

' 定义按钮的宽度和高度
Dim buttonWidth As Integer = 100
Dim buttonHeight As Integer = 30

' 定义每行和每列的按钮个数
Dim buttonsPerRow As Integer = 3
Dim rowsCount As Integer = 4

' 定义起始位置
Dim startX As Integer = 10
Dim startY As Integer = 10

' 循环创建按钮并添加到Panel中
For i As Integer = 0 To (buttonsPerRow * rowsCount) - 1
    Dim btn As New Button()
    btn.Text = "Button " & (i + 1)
    btn.Width = buttonWidth
    btn.Height = buttonHeight
    btn.Left = startX + (i Mod buttonsPerRow) * (buttonWidth + 10)
    btn.Top = startY + (i \ buttonsPerRow) * (buttonHeight + 10)
    SplitContainer1.Panel1.Controls.Add(btn)
Next

此代码创建若干个Button控件，并按照指定的规则排列它们。您可以根据需要修改按钮的宽度、高度、每行和每列的按钮个数、起始位置等参数。
