Add-Type $c
$z = [Zoo]::new()
$z.psobject.Methods["GetName"].Invoke("Hello")Expected behavior
Success just like running $z.GetName("Hello"):
PS> $z.GetName("Hello")
Hello

PS> $z.psobject.Methods["GetName"].Invoke("Hello")
Exception calling "GetName" with "2" argument(s): "Object reference not set to an instance of an object."
