dll - Powershell Call Assembly Delegate -

i have dll assembly our process control application, use load inside powershell script.

the dll contains delegate type need use, delegate name :

"x.y.delegate" 

i have method in dll should called way :

method( delegatetype callbackmethod) 

so, need :

1. define delegate in script of type "x.y.delegate" example $mydelegate

2. define callback method gets invoked when process event triggered"

note: i'm sorry if question seems silly, i'm absolute beginner.

update:

after reading comment , reading question more closely, think might looking utilize asynchronous event handling. below example listens events until timeout reached , exits. example assumes can change assembly add event.

a class generates events:

namespace classlibrary1 {  public class class1  {   public event eventhandler someevent;    protected void onsomeevent(eventargs e)   {    var someevent = someevent;     if (someevent != null)    {     someevent(this, e);    }  }   public void somemethod()  {   task.run(() =>   {    (int = 0; < 3; i++)    {     thread.sleep(3000);     onsomeevent(eventargs.empty);     }    });   }  } } 

powershell:

# load .net assembly add-type -path .\class1.cs   $x = new-object classlibrary1.class1  $sourceidentifier = "someevent"  # register event $eh = register-objectevent -sourceidentifier $sourceidentifier -inputobject $x -eventname someevent  $x.somemethod()  while ($true) {  write-host "waiting event..."  $event = wait-event -sourceidentifier $sourceidentifier -timeout 10   if ($event -eq $null)   {   write-host "no event received 10 seconds."    break   }   # processing here  write-host "processing event..."  $event   # remove event queue  remove-event -sourceidentifier $sourceidentifier }  unregister-event -sourceidentifier $sourceidentifier write-host "done processing events."
