Make Choices to Enable / Disable Net Adapter Using Powershell

I'm Trying to use Powershell to make a choices to Enable/Disable Net Adapter "Ethernet" I Coded This 

$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}
}

Error :

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

I have failed before this to do On/Off script using powershell (if the net adapter is enable then disable it and vice versa. is there any way to do this?

Using this: https://technet.microsoft.com/en-us/library/ff730939.aspx I think what you want to be doing is the following:

$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
    }
}

The approach you were taking wasn't working because you were trying to assign a process to a ChoiceDescription array. In the example above, you have to first create two ChoiceDescription objects before assigning them to the array
