使用 Powershell 选择启用/禁用网络适配器

Question

我正在尝试使用 Powershell 来选择 Enable/Disable 网络适配器 "Ethernet" 我编码了这个

$caption = "Choose Action";
$message = "What do you want to do?";
$enab = start-process powershell -verb runas -argument D:\ena.ps1
$disa = start-process powershell -verb runas -argument D:\dis.ps1
$choices = [System.Management.Automation.Host.ChoiceDescription[]]($enab,$disa);
$answer = $host.ui.PromptForChoice($caption,$message,$choices,0)
switch ($answer){
0 {"You entered Enable"; break}
1 {"You entered Disable"; break}
}

错误：

Object cannot be stored in an array of this type. At D:\Untitled4.ps1:5 char:1 + $choices = System.Management.Automation.Host.ChoiceDescription[]; + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OperationStopped: (:) [], InvalidCastException + FullyQualifiedErrorId : System.InvalidCastException

Exception calling "PromptForChoice" with "4" argument(s): "Value cannot be null. Parameter name: choices" At D:\Untitled4.ps1:6 char:1 + $answer = $host.ui.PromptForChoice($caption,$message,$choices,0) + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : ArgumentNullException

在此之前，我未能使用 powershell 执行 On/Off 脚本（如果启用了网络适配器，则禁用它，反之亦然。有什么办法可以做到这一点吗？

使用这个：https://technet.microsoft.com/en-us/library/ff730939.aspx我想你想要做的是：

$caption = "Choose action:"
$message = "What state do you want for the network adapter?"

$enable = New-Object System.Management.Automation.Host.ChoiceDescription "&Enable", `
    "Enables the Network Adapter"

$disable = New-Object System.Management.Automation.Host.ChoiceDescription "&Disable", `
    "Disables the Network Adapter"

$options = [System.Management.Automation.Host.ChoiceDescription[]]($enable, $disable)

$result = $host.ui.PromptForChoice($caption, $message, $options, 0) 

switch ($result)
{
    0 { 
        "You selected Enable." 
        start-process powershell -verb runas -argument D:\ena.ps1
    }
    1 {
        "You selected Disable."
        start-process powershell -verb runas -argument D:\dis.ps1
    }
}

您采用的方法无效，因为您试图将 process 分配给 ChoiceDescription 数组。在上面的示例中，您必须先创建两个 ChoiceDescription 对象，然后再将它们分配给数组
