In powershell functions i can have something like
Function myFunction { Param( [Parameter(Mandatory=$True)][string]$foo, [Parameter(Mandatory=$False)][string]$bar = "whatever" ) .... } But this seems limited to functions - is there something similar for method?
class MyClass { ... [void]MethodA { Param( .... dont works for me.
The interpreter complains about the missing '(' in the class method parameter list.
Adding methods to classes works just like in most other scripting languages one might know. Instead of [void]MethodA {Param()...} you might want to add a block like described in this blog post or here:
class MyClass { #... [void]MethodA ($param) { #... } } As your title says optional parameters (but your question doesn't) a short word on that...
Usually you want multiple signatures for such cases. That means you create a method MethodA($arg1, $arg2) and a delegating method like MethodA($arg1) {MethodA($arg1, $null)}
