Event

事件关联的委托是按顺序串行执行的。

using System;

namespace EventDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            Job job = new Job();
            job.DoJob();
        }
    }

    class Job
    {
        public delegate void JobHandle(int max);
        public event JobHandle OnWork;
        public Job()
        {
            OnWork += new JobHandle(new Job1().DoJob);
            OnWork += new JobHandle(new Job2().DoJob);
        }
        public void DoJob()
        {
            OnWork(5);
        }
    }

    class Job1
    {
        public void DoJob(int max)
        {
            for (int i = 0; i < max; i++)
            {
                Console.WriteLine("[{0}]{1}", this, i);
                System.Threading.Thread.Sleep(2000);
            }
        }
    }

    class Job2
    {
        public void DoJob(int max)
        {
            for (int i = 0; i < max; i++)
            {
                Console.WriteLine("[{0}]{1}", this, i);
                System.Threading.Thread.Sleep(1000);
            }
        }
    }

}
