Invoking Function in PowerShell via String

Question

I'm trying to Invoke a Powershell function "dynamically" using a string. Example

$functionToInvoke = "MyFunctionName";

Invoke-Function $functionToInvoke $arg1 $arg2  #  <- what I would like to do

Is there any way to achieve this with PowerShell 2.0 ?

You can do this:

 &"MyFunctionName" $arg1 $arg2

How would you call a function named start? It seems to get picked up by cmd? Might not be saying that correctly... are there ways around this kind of thing in powershell? or do I just have to name my method differently?

If you want to make variables from the whole thing use Invoke-Expression:

function myfunctionname {write-host "$($args[0]) $($args[1])"}
$arg1 = "scripts"
$arg2 = "test"

$functionToInvoke = "MyFunctionName";


Invoke-Expression  "$functionToInvoke $arg1 $arg2"

scripts test
