C # syntax exercise (13): class [5]-Indexer

The indexer allows you to easily use the Array (or set) members in the class:

Using system; Class myclass {private float [] FS = new float [3] {1.1f, 2.2f, 3.3f};/* attribute */Public int length {get {return FS. length ;}set {FS = new float [value] ;}/ * indexer */public float this [int N] {get {return FS [N];} set {FS [N] = value ;}} class program {static void main () {myclass OBJ = new myclass (); For (INT I = 0; I

Other values can be used as index types:

Using system; Class myclass {public int this [String STR] {get {return Str. length ;}} class program {static void main () {myclass OBJ = new myclass (); console. writeline (OBJ ["123"]); // 3 console. writeline (OBJ ["ABCD"]); // 4 console. readkey ();}}
