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

Use a hashtable, indeed!

#TestPs1.ps1
Param (
    [string]$P3,
    [string]$P2,
    [string]$P1
)
Write-Output "P1 Value :" $P1
Write-Output "P2 Value:" $P2
Write-Output "P3 Value :" $P3

$params = @{
    P3 = 3
    P2 = 2
}
#(just to prove it doesn't matter which order you put them in)
$params["P1"] = 1;
#Trhough the use of the "Splat" operator, we can add parameters directly onto the module
& ".\TestPs1.ps1" @params

outputs:

P1 Value :
1
P2 Value:
2
P3 Value :
3
