Invoking Function in PowerShell via String

问题

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 ?

回答1:

You can do this:

 &"MyFunctionName" $arg1 $arg2

回答2:

If you're wanting to variableize the whlole thing:

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

$functionToInvoke = "MyFunctionName";


invoke-expression  "$functionToInvoke $arg1 $arg2"

scripts test
