上面文章介紹了委託、匿名的定義,下面的例子則是由繁入簡,廢話很少說,直接上代碼: class Program { private delegate int sum(int x, int y); private delegate int MyMulticastDelegate(int x, int y); static void Main(string[] args) { Console.WriteLine("委託方式一加法:"); sum addsum = new sum(add); int y = addsum(2, 3); Console.WriteLine("委託方式一加法:2+3" + y); Console.WriteLine("多波委託:有的時候,咱們想要調用一個委託,但同時能夠執行多個方法(自定義事件中最爲常見),好比,一個工做文檔生成以後,系統要將生成文檔日誌,並且還要被保存到數據庫中,對於以上二個操做,若是隻想調用一個委託,就能夠順序完成,那麼使用多播委託,就能夠實現。"); MyMulticastDelegate sumdele = new MyMulticastDelegate(add); MyMulticastDelegate subdele = new MyMulticastDelegate(sub); MyMulticastDelegate multicastDelegate = sumdele+subdele; multicastDelegate(2,2); Console.WriteLine("委託中的匿名方法(未簡化):"); sum Nofuntion = new sum(delegate( int x,int i) { return x * i; }); int k = Nofuntion(2,3); Console.WriteLine(k); Console.WriteLine("委託中的匿名方法(簡化):"); sum _sum =(int x, int m)=>{ return x * m; }; int z = Nofuntion(2, 3); Console.WriteLine(z); Console.ReadKey(); } private static int add(int x, int y) { Console.WriteLine(x+y); return x + y; } private static int sub(int x, int y) { Console.WriteLine(x - y); return x - y; } private static void mulitey(int x, int y) { Console.WriteLine(x * y); } }
