Not understand the purpose of Indexers. Example:

C#

class MyCls
{
   object[] myArr = new object[];
   public object this[int i]
   {
      get{return myArr[i];}
      set{myArr[i] = value;}
   }
}

Why not just create a property for myArr and access it through it's property?
What's the advantage and/or purpose of using an Indexer?

Right! Why not just create a property with the distinct name? There is nothing principal about this feature.

This is nothing more than the syntactic sugar, see http://en.wikipedia.org/wiki/Syntactic_sugar[^].

Being the syntactic sugar, this is very nice sugar, following nice tradition from other languages.
