将多个变量传递给参数

Question

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

我正在使用上面的 cmdlet 在 vSphere 中添加一个新的 vSwitch，我所缺乏的知识是如何使用代表四个 NIC 的四个复选框，并在选中时传递给 -Nic 参数。

例如下面的行不通

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

如语法所示，如何将每个复选框的变量传递给字符串数组？

$handler_linkLabel601_LinkClicked= 
{
if ($networkdataGridView.CurrentRow.Cells['VM Host'].Value.toString() -gt " ")

Answer 1

正如 C.B. 所说，将 $nic0 替换为 $global:nic0，将 $nic1 替换为 $global:nic1 等。 然后测试是

function test
{
    $nic = @($global:nic0,$global:nic1,$global:nic2,$global:nic3 | ? {-not [string]::IsNullOrEmpty($_)})
    if ( $nic.count )
    {
        New-VirtualSwitch -VMHost $comboBox611.SelectedItem.toString() -Name $textBox611.Text -NumPorts 200 -Nic $nic -Mtu $textBox612.Text -Confirm
    }
}
