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
