The    operator is called an indexer  You can provide indexers that take an integer  a string  or any other type you want to use as a key  The syntax is straightforward  following the same principles as property accessors   For example  in your case where an int is the key or index   public int this int index        get   gt  GetValue index       You can also add a set accessor so that the indexer becomes read and write rather than just read-only   public int this int index        get   gt  GetValue index       set   gt  SetValue index  value       If you want to index using a different type  you just change the signature of the indexer   public int this string index

I believe this is what you are looking for   Indexers  C  Programming Guide   class SampleCollection lt T gt        private T   arr   new T 100       public T this int i                get   gt  arr i           set   gt  arr i    value              This class shows how client code uses the indexer class Program       static void Main string   args                SampleCollection lt string gt  stringCollection                new SampleCollection lt string gt             stringCollection 0     Hello  World           System Console WriteLine stringCollection 0
