Dim cob1 As WinForm.ComboBox = e.Form.Controls("ComboBox1")\'串口
Dim cob2 As WinForm.ComboBox = e.Form.Controls("ComboBox2")\'波特率
Dim cob3 As WinForm.ComboBox = e.Form.Controls("ComboBox3")\'数据位

Ports.Add(cob1.Text)

    With Ports(cob1.Text)
        .Close()
        .Encoding=Encoding.ASCII
        .BaudRate = cob2.Text
        .DataBits = cob3.Text
        .Parity = "Parity." & cob5.Text       \'奇效验   值是 odd
        .StopBits = "StopBits." & cob4.Text  \'停止位  1 值是 one

        \'.WriteBufferSize() = 4096

    End With
end if



上述两个红字要怎么写?

对象类型是不能直接使用字符串表示的

.Parity = [Enum].Parse(Gettype(Parity), cob5.Text )
