How can I get all keys of a hashtable ?


Recommended Posts


I need associative arrays like in PHP or Perl. As a solution I found code like the lines below:

$hash = ObjCreate("System.Collections.Hashtable")
  $hash.add ("key1", "val1")
  $hash.add ("key2", "val2")

  ; Getting the number of elements in my hash table works
  $count = $hash.Count
  ConsoleWrite("count = " & $count & @CRLF)    

  ; Getting the number of elements in my hash table works
  $keys = $hash.Keys
  ConsoleWrite("keys = " & _ArrayToString($keys) & @CRLF)

In another posting Topic 106907 I found a solution based on ObjCreate("Scripting.Dictionary"). Here you can get all keys using the keys property:

Func _DictKeys($oDict)
    If Not IsObj($oDict) Then Return SetError(1, 0, False)
    Return $oDict.keys

Does anybody know how to do this with .net hashtables? I've tried to use something like

$enum = $hash.GetEnumerator()
  loop using $enum.MoveNext()

but it does not work. I'm not sure if autoit can use the object of type "System.Collections.IDictionaryEnumerator" which is returned by GetEnumerator.

Thanks a lot in advance, Pat

using .NET-COM-Objects in AutoIt has some limitations. You found one :mellow:

You should use Scripting.Dictionary instead.

Or you could use Nutster's Associative Array UDF from here.

I use it in preference to the Scripting.Dictionary tool as it does not require any pre-installed libraries (although to be honest it must be pretty hard to find a machine without them nowadays :mellow:).
