Answer 1

Hmm That is a very hard task, but Captain Algorithm will help you! He is telling us that there are many ways to do this. One of them he give me and I give it to you:

Dictionary  tmp = new Dictionary  ();

foreach (Object obj in YourArray)
  if (!tmp.ContainsKey(obj))
    tmp.Add (obj, 1);
 else tmp[obj] ++;

tmp.Values;//Contains counts of elements
