PowerShell Pass Named parameters to ArgumentList

Question

I have a PowerShell script that accepts 3 named parameters. Please let me know how to pass the same from command line. I tried below code but same is not working. It assigns the entire value to P3 only. My requirement is that P1 should contain 1, P2 should 2 and P3 should be assigned 3.

Invoke-Command -ComputerName server -FilePath "D:\test.ps1" -ArgumentList  {-P1 1 -P2 2 -P3 3}

Ihe below is script file code.

Param (
    [string]$P3,
    [string]$P2,
    [string]$P1
)
Write-Output "P1 Value :" $P1
Write-Output "P2 Value:" $P2
Write-Output "P3 Value :" $P3

Answer 1

One option:

$params = @{
P1 = 1
P2 = 2 
P3 = 3
}

$ScriptPath = 'D:\Test.ps1'

$sb = [scriptblock]::create(".{$(get-content $ScriptPath -Raw)} $(&{$args} @params)")

Invoke-Command -ComputerName server -ScriptBlock $sb

Answer 2

Here's a simple solution:

[PowerShell]::Create().AddCommand('D:\test.ps1').AddParameters(@{ P1 = 1; P2 = 2; P3 = 3 }).Invoke()

Here's output:

PS C:\Windows\system32> [PowerShell]::Create().AddCommand('D:\test.ps1').AddParameters(@{ P1 = 1; P2 = 2; P3 = 3 }).Invoke()
P1 Value :
1
P2 Value:
2
P3 Value :
3
