how to export a class in powershell v5 module

Question

I\'ve got a module setup to be like a library for a few other scripts. I can\'t figure out how to get a class declaration into the script scope calling Import-Module

Answer 1

the using statement is the way to go if it works for you. otherwise this seems to work as well.

testclass.psm1

Use a function to deliver the class

class abc{
    $testprop = 'It Worked!'
    [int]testMethod($num){return  $num * 5}
}

function new-abc(){
    return [abc]::new()
}

Export-ModuleMember -Function new-abc

someScript.ps1

Import-Module path\to\testclass.psm1
$testclass = new-abc
$testclass.testProp        # returns 'It Worked!'
$testclass.testMethod(500) # returns 2500
