When should you use C# indexers?

Question

I\'d like to use indexers more, but I\'m not sure when to use them. All I\'ve found online are examples that use classes like MyClass and IndexerClass

Answer 1

Indexers allow instances of a class or struct to be indexed just like arrays. Indexers resemble properties except that their accessors take parameters.

Indexers enable objects to be indexed in a similar manner to arrays.

    // C#: INDEXER 
using System; 
using System.Collections; 

class MyClass 
{ 
    private string []data = new string[5]; 
    public string this [int index] 
    { 
       get 
       { 
           return data[index]; 
       } 
       set 
       { 
           data[index] = value; 
       } 
    } 
}

class MyClient 
{ 
   public static void Main() 
   { 
      MyClass mc = new MyClass(); 
      mc[0] = "Rajesh"; 
      mc[1] = "A3-126"; 
      mc[2] = "Snehadara"; 
      mc[3] = "Irla"; 
      mc[4] = "Mumbai"; 
      Console.WriteLine("{0},{1},{2},{3},{4}",mc[0],mc[1],mc[2],mc[3],mc[4]); 
   } 
}
