============================================多播委托
-------------------------------------主程序
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { //多播委托只能使用无返回值的委托 //当str1执行失败后会阻止后面的方法的执行 Action<string> a = str1; a += str2; a += str2; a += str2; a += str2; StrAndName(a, "文聘"); Console.ReadKey(); } static void str1(string name) { Console.WriteLine("看我{0}的厉害", name); } static void str2(string name) { Console.WriteLine("受死吧!{0}", name); } static void StrAndName(Action<string> action, string name) { action(name); } } }
============================================匿名方法
-------------------------------------主程序
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication4 { class Program { static void Main(string[] args) { string s = "你好!"; //不能使用break,goto,continue,ref,out Action<string> a = delegate(string str) { Console.WriteLine(s + str); Console.ReadKey(); }; a("我叫张飞"); } } }
