动态加入控件时，为什么后添加的控件Index值小而先添加的值更大呢？
dim xpage as new TabPage()
dim xcon as myControl
xcon=new Mycontrol
xPage.Controls.Add(xCon)

用以上方法在页面里添加了控件后发现 后加的控件Index值最小，通常我们往一个集合里加东西都是先加入的index小后加的值大。为什么这里会是这样呢？会不会有什么巧门？

用以下代码测试了下，没发现后加的Index值小啊

VB.NET code

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        Dim tab As New TabPage With {.Text = "test"}        For i As Integer = 0 To 5            Dim btn As New Button With {.Text = "Button" + i.ToString}            btn.Top = btn.Height * i + 10            tab.Controls.Add(btn)        Next        For Each Button As Button In tab.Controls            MsgBox(Button.Text + "  " + tab.Controls.IndexOf(Button).ToString)        Next    End Sub
