Answer 1

Dictionaries are unordered; elements are meant to be retrieved with a key, whose hash points to its value's location.

What you might want is a List , whose elements can be inserted into a specific index.

List> list = dic.ToList();
list.Insert(0, new KeyValuePair("a", "b"));

foreach(KeyValuePair pair in list)
    Console.WriteLine("{0} = {1}", pair.Key, pair.Value);
