Indexer_this1.cs
  • Indexers can be viewed as a smart array,
  • Indexers are similar to properties except that their accessors take parameters.
  • This "this" stands as suffix to the class
    • public type this [int index] // Indexer declaration
    • public int this [int index] // Indexer declaration Integer parameter
    • public string this [string index] // Indexer declaration string parameter
