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 :

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
