{
Console.WriteLine("请帮我把资料发给客户");
AskEvent();
}
}
public static void Main()
{
Master me = new Master();
Employee x1 = new Employee("小王");
Employee x2 = new Employee("小李");
Employee x3 = new Employee("小赵");
me.AskEvent += new AskEventHandler(x1.DoWorkByTele);
me.AskEvent += new AskEventHandler(x2.DoWorkByEmail);
me.AskEvent += new AskEventHandler(x3.DoWorkByWechart);
me.Ask();
me.AskEvent -= new AskEventHandler(x1.DoWorkByTele);
me.Ask();
Console.ReadLine();
}
}
public class Employee
