Real world use cases for C# indexers?

Question

I\'ve seen lot of examples for c# Indexers, but in what way will it help me in real life situations.

I know the C# guru wouldn\'t have added this if it wasn\'t a ser

Indexers are elements in a C# program that allow a Class to behave as an Array. You would be able to use the entire class as an array. In this array you can store any type of variables. The variables are stored at a separate location but addressed by the class name itself. Creating indexers for Integers, Strings, Boolean etc. would be a feasible idea. These indexers would effectively act on objects of the class.

Lets suppose you have created a class indexer that stores the roll number of a student in a class. Further, lets suppose that you have created an object of this class named obj1. When you say obj1[0], you are referring to the first student on roll. Likewise obj1[1] refers to the 2nd student on roll.

Therefore the object takes indexed values to refer to the Integer variable that is privately or publicly stored in the class. Suppose you did not have this facility then you would probably refer in this way(which would be longer):

obj1.RollNumberVariable[0]
obj1.RollNumberVariable[1]. 

where RollNumberVariable would be the Integer variable that refers to the Roll Number of the current student object.
