To	Do this
Create an indexer for a class or struct	Declare the type of the indexer, followed by the keyword this, and then the indexer arguments between square brackets. The body of the indexer can contain a get and/or set accessor. For example: struct RawInt {     ...     public bool this [ int index  ]     {         get { ... }         set { ... }     }     ... }
Define an indexer in an interface	Define an indexer with the get and/or set keywords. For example: interface IRawInt {     bool this [ int index ]  get;  set; } }
Implement an interface indexer in a class or struct	In the class or struct that implements the interface, define the indexer and implement the accessors. For example: struct RawInt : IRawInt {     ...     public bool this [ int index  ]     {         get { ... }         set { ... }     }     ... }
Implement an interface indexer by using explicit interface implementation in a class or struct	In the class or struct that implements the interface, explicitly name the interface, but do not specify the indexer accessibility. For example: struct RawInt : IRawInt {     ...     bool IRawInt.this [ int index  ]     {         get { ... }         set { ... }     }     ... }
