C # delegate Case and understanding

The following uses the employee to play the game, the boss deduction salary case:

   Class Boss {private int money = 20;                    public void rsalary (int wage) {Console.WriteLine ("Boss found deduction of wages {0}￥, remaining {1}", Money,wage-money); }} class Employment {//In order to reduce the boss's work, while low coupling, use the delegate instead of the boss work public delegate void Pghandler (in        t pay);//define Parameters Delegate public event Pghandler pgevent;//Define event//boss bs = new Boss ();        public string name= "bin";        public string number= "S-0001";        public int wage=5000;            public void PlayGame () {Console.WriteLine ("Employee {0} play game, work number {1}", name, No.);            if (pgevent! = null) {//If there is an object registered pgevent (wage);//method that invokes all registered objects} Bs.        Rsalary ();//The most primitive, the employee plays the game to call the Boss class deduction salary method.            } public void Chat () {Console.WriteLine ("Employee {0}qq Chat, work number {1}", Name,number);            if (pgevent! = null) {pgevent (wage); }//bs.      Rsalary ();  }} class Program {static void Main (string[] args) {Employment em = new Employment ()            ;            Boss BS = new boss (); Em. Pgevent + = BS. rsalary;//Registration method em. PlayGame ();//play games, will automatically call the registration of the deduction method of wages em.            Chat ();        Console.ReadLine (); }    }}
