Calling a static method by reflection from PowerShell

Question

I'm reading information on various objects from an XML file and need to instantiate and set values on these objects from PowerShell.

This is a sample where UInt32.Parse(string) should be retrieved using Reflection. The problem is the $mi variable is null:

$o = new-object -typename "System.UInt32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
$mi = $o.GetType().GetMethod("Parse", [type[]] @([string].GetType()) )

The corresponding C# code works:

UInt32 o = 0;
var mi = o.GetType().GetMethod("Parse", new [] {typeof(string)});

Any ideas?

Do you need to use reflection? Perhaps you could use $parse = [system.uint32]::Parse and $parse.Invoke($arg) instead.
