How do I get the list of keys in a Dictionary?

Question

I only want the Keys and not the Values of a Dictionary.

I haven\'t been able to get any code to do this yet. Using another array proved to be too much work as I use

Answer 1

The question is a little tricky to understand but I'm guessing that the problem is that you're trying to remove elements from the Dictionary while you iterate over the keys. I think in that case you have no choice but to use a second array.

ArrayList lList = new ArrayList(lDict.Keys);
foreach (object lKey in lList)
{
  if ()
  {
    lDict.Remove(lKey);
  }
}

If you can use generic lists and dictionaries instead of an ArrayList then I would, however the above should just work.
