Question

When I run this code it results in $o having a Name property with no value, even though I passed ‘MyObj’ as the name. What am I doing wrong?

Thanks for any help.

function CreateSomething {
    param( [string] $name )

    $o = new-object PSObject
    write-host '$name:' $name
    $o | add-member -name Name -passThru -force -memberType ScriptProperty -value { $name }
   $o
}

$o = CreateSomething -name MyObj
$o

What are you trying to achieve here?

The -value { $name } will be the scriptblock that is used for the ScriptProperty and it has no idea of $name ( it is not in scope)

You can do it this way:

$o | add-member -name Name -passThru -force -memberType ScriptProperty -value { $name }.GetNewClosure()

I don’t see why you can’t just do:

$o | add-member -name Name -passThru -force -memberType NoteProperty -value $name

Note: Since you are using -passThru in the above statement, you can omit the lone $o in the last line of your function.
