使用控制访问迭代MenuStrip的所有项目

Question

当我尝试遍历所有MenuStrip时，我不知道如何进行迭代 使用MenuStrip之类的控件

这里是代码

Public Sub FindAllChildren(ByRef StartingContainer As System.Windows.Forms.Control.ControlCollection)
    For Each child As Control In StartingContainer
        'MsgBox(child.Name)
        If (child.GetType() Is GetType(MenuStrip)) Then
            soonmenustrip(child.Container)
        Else
            MsgBox(child.Name)
        End If

        If child.HasChildren Then
            FindAllChildren(child.Controls)
        End If

    Next
End Sub

Public Sub soonmenustrip(ByRef StartingContainer As MenuStrip)
    For Each t As ToolStripItem In StartingContainer.Items
        MsgBox(t.Name)
    Next
End Sub

发给我错误 错误1“项目”不是“System.Windows.Forms.Control”
