        Dim p_country As WinForm.picturebox = e.Form.Controls("Pb_国家")
        Dim countrylist As String = ""
        For Each c As WinForm.PictureBox In p_country.children
            countrylist = countrylist & "," & c.Name
        Next
红色的部分编译没问题,但完全没有执行

Dim fm As WinForm.Form = forms(args(0)) \'窗口名
Dim PName As String = args(1) \'picturebox名

Dim pa As WinForm.PictureBox= fm.Controls(PName)
Dim pbx As WinForm.PictureBox
For Each p As String In ps
    pbx = fm.CreateControl(p, ControlTypeEnum.PictureBox)
    pa.AddControl(pbx)
    pbx.ToolTip = p
    pbx.Width = 53
    pbx.Height = 39
    pbx.Left = x
    pbx.Top = y
    If p <> "" Then
    pbx.ImageFile = p & ".png"
    Else
    pbx.ImageFile =  "问号.png"
    End If
    pbx.SizeMode = ImageSizeMode.Zoom    
     x = x + 60
    If x+60 > pa.Width Then
        x = 2
        y = y + 42
    End If
Next

应该是bug，我反馈一下

临时先换种用法

Dim p_country As WinForm.picturebox = e.Form.Controls("Pb_国家")

For Each c As Object In p_country.BaseControl.Controls(0).Controls
    msgbox(c.Name)
Next
