Powershell: Create a Script Block

The following function crate-script-block creates a script block that captures the value of the parameter $var with which it was created.

In order for this to work, GetNewClosure must be executed on the initial script block.

The returned scrip block also takes a parameter which is assigned when the script block is executed.

function create-script-block {
   param ($var)

   return {
      param($p)
      write-host "p = $p, var = $var"
   }.GetNewClosure()
}


$s1 = create-script-block  42
$s2 = create-script-block 'hello world'

& $s1 'one'
& $s2 'two'
