How to pass array of arguments to Powershell commandline

Short answer: More double quotes could help...

suppose the script is "test.ps1"

param(

    [Parameter(Mandatory=$False)]
    [string[]] $input_values=@()

)
$PSBoundParameters

Suppose would like to pass the array @(123,"abc","x,y,z")

Under Powershell console, to pass multiple values as an array

.\test.ps1 -input_values 123,abc,"x,y,z"

Under Windows Command Prompt Console or for Windows Task Scheduler; A double-quote are replaced by 3 double-quotes

powershell.exe -Command .\test.ps1 -input_values 123,abc,"""x,y,z"""

Hope it could help some

try

Powershell -command "c:\pathtoscript\InvokeBuildscript.ps1" "z:\" "Component1,component2"

if test.ps1 is:

$args[0].GetType()
$args[1].gettype()

call it from a dos shell like:

C:\>powershell -noprofile -command  "c:\script\test.ps1" "z:" "a,b"

returns :

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String                                   System.Object
True     True     Object[]                                 System.Array

One can also pass array variables as command line arguments. Example:

Consider the following Powershell Module

File: PrintElements.ps1

Param(
    [String[]] $Elements
)

foreach($element in $Elements)
{
   Write-Host "element: $element"
}

To use the above powershell module:

#Declare Array Variable
[String[]] $TestArray = "Element1", "Element2", "Element3"

#Call the powershell module
.\PrintElements.ps1 $TestArray

And if you want to concatenate and pass the TestArray as a single string of space separated elements then you can call the PS module by enclosing the argument in quotes as shown below:

#Declare Array Variable
[String[]] $TestArray = "Element1", "Element2", "Element3"

#Call the powershell module
.\PrintElements.ps1 "$TestArray"
