Indexer vs function

[axos88]

What is the difference, and why is one better then the other? I mean indexer vs public foo Items(string name) { some code here; return respective item; } Thanks, Vandra Akos

on the righthand side of a statement, a function can perfectly replace an indexer. On the lefthand side it can't.

// You can write:

var = object[index]; // or var=object.someMethod(index);

// but also:

object[index] = value;
object[index]++;

Of course, one can live without indexers (as C and Java have proven) but they make it possible to improve code readability. :) -- modified at 17:07 Thursday 28th December, 2006
