Passing array to another script with Invoke-Comman

问题:

I'm stuck trying to figure this out. I've seen the other articles and have tried everything, but I'm not getting anywhere. I am trying to pass an array as an argument to another PS script. Here's what I'm trying:

$IPArray = Get-Content C:\ListofIps.txt
Invoke-Command -Computername $server -Credential $cred -FilePath "C:\script.ps1" -ArgumentList (,$IPArray)

The 5 values in $IPArray aren't being passed to the script that I call.

Thanks in advance, guys, I really appreciate any help you can give...

回答1:

Use:

... -ArgumentList (,$IPArray)

Because the ArgumentList parameter expects an array you've correctly noted that you need to wrap the array in another array. However, the correct syntax in this scenario (specifying a parameter value) is to use a grouping expression () to create the nested array.

This is an old question, but I'm going to re-iterate @keith-hill on the answer--add a comma at the beginning of the array declaration (even when including an existing array).

It's stupid, but I'm answering again because I tried all alternatives and that's the only thing that works--even with PowerShell 3.0+. You can use #require for anything from at least v3.0+, but nothing will work unless you do what @keith-hill suggests--even though it's an array, and the parameter is an array, PS sucks in this case (and I love PS)...do what he said (posting didn't work, so sorry but working answers are better): \ ... -ArgumentList (,$IPArray)

It makes no sense, but that works. Hands down to the PS team for dropping the bomb on this one, but if I hadn't done that my script would be null and void. And I've become the "scripting guy"...so here you go.
