lambda

class Program

public deleget void xxxx(string str);      代理是以方法为参数的类

xxxx x=new xxxx(zhixing);                      代理的实例化  简写:匿名方法  xxxx x=new xxxx(deleget(string s){console.write(s);})

                          lambda           xxxx x=new xxxx(()=>{console.write("aaaaaaaaaaaa");})

x.invoke();             代理执行

public void zhixing(string s)
