Yes, you can overload indexers in C#. The purpose of overloading is just the same as why you'd want to overload a method  - to allow it to be called with different numbers or types of parameters.
Here's an example:
using System;
class NamesCollection {    string[] names;       public string this[int index]    {       get { return names[index]; }       set { names[index] = value; }    }
public int this[string name]    {       get       {          for(int i = 0; i          {             if (names[i] == name) return i;          }          return -1;       }      }
public NamesCollection(string[] names)    {       this.names = names;    } }
class Test {    static void Main()    {       string[] names = {"Fred", "Dave", "Diana"};       NamesCollection nc = new NamesCollection(names);       Console.WriteLine(nc[1]); // Dave       Console.WriteLine(nc["Diana"]); // 2       Console.ReadKey();    } }
