主题：改变窗口中某一个容器内控件的字体及背景

改变窗口中某一个容器内控件的字体及背景，写了红色部分的代码，但是提示错误，该怎么处理，比如我想改变分区面板panel2中的控件

Dim fnt As New Font("黑体",12,FontStyle.Underline)
For Each c As Winform.Control In e.Form.Controls
'For Each c As Winform.Control In e.Form.Controls("SplitContainer1")
    c.BackColor = Color.LightPink
c.Font = fnt
