arrays - 複数の変数をパラメーターに渡す

Question

構文：New-VirtualSwitch [-VMHost] [-Name] [[-NumPorts]] [[-Nic] String []]

上記のコマンドレットを使用して、vSphereに新しいvSwitchを追加しています。知識が不足しているのは、4つのNICを表す4つのチェックボックスを使用する方法であり、チェックすると-Nicパラメーターに渡されます。

たとえば、以下は機能しません

New-VirtualSwitch -VMHost $comboBox611.SelectedItem.toString() -Name $textBox611.Text -NumPorts 200 **-Nic $nic0,$nic1,$nic2,$nic3** -Mtu $textBox612.Text -Confirm

構文が示すように、各チェックボックスの変数を文字列配列に渡すにはどうすればよいですか？
