c# 初識Actor Model

標籤：output   ring   國外   let   linq   實現   account   comm   logs   

最近學了點 c# dataflow的一些東西，然後國外有個人，用dataflow來實現了，一個Actor模型；

這裡做個比較，算是初識我們的actor模型，然後我們再進一步的深入瞭解一哈；

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Threading.Tasks.Dataflow;namespace Actor_Model{    //actor model 的基本使用和樣本；    //https://blog.jayway.com/2013/11/15/an-actor-model-implementation-in-c-using-tpl-dataflow/#comment-463337    public abstract class Message { }    //把所有的action 都通過meg的 形式表達出來；    //吧我們的每一動作都看成了資訊；讓後將資訊傳遞出去，真正的執行，交給我們的具體的actor去執行滴呀；    public class Deposit : Message    {        public decimal Amount { get; set; }    }    //To check the balance we send a QueryBalance message    public class QueryBalance : Message    {        //The result of the query should be sent as a message to another actor        //也就是說查詢出來的資訊又交給了另外一個actor 處理了滴呀；資訊之間的傳遞；        public Actor Receiver { get; set; }    }    //The final message is the result of the balance chec    public class Balance : Message    {        public decimal Amount { get; set; }    }    public abstract class Actor    {        private readonly ActionBlock<Message> _action;        public Actor()        {            _action = new ActionBlock<Message>((msg =>              {                  dynamic self = this;                  dynamic mess = msg;                  self.Handle(mess);              }));        }        public void Send(Message msg)        {            _action.Post(msg);        }        public Task Completion        {            get            {                _action.Complete();                return _action.Completion;            }        }    }    //Each account has a balance. We want to be able to deposit money and check the balance    //實際動作的執行者；    public class AccountActor : Actor    {        private decimal _balance;        //存錢        public void Handle(Deposit msg)        {            _balance += msg.Amount; //deposite money         }        //查詢餘額        public void Handle(QueryBalance msg)        {            //查詢出來的餘額，叫給我們的額新actor去處理；            //相當於建立一個新的acto            msg.Receiver.Send(new Balance { Amount = _balance });        }    }    //We also need an actor that outputs the result of the balance query    public class OutputActor : Actor    {        public void Handle(Balance msg)        {            Console.WriteLine("Balance is {0}", msg.Amount);        }    }    class Program    {        static void Main(string[] args)        {            var account = new AccountActor();            var output = new OutputActor();            account.Send(new Deposit { Amount = 50 });            account.Send(new QueryBalance { Receiver = output });            account.Completion.Wait();            output.Completion.Wait();            Console.WriteLine("Done!");            Console.ReadLine();        }    }}

看完基本瞭解actor，但是還是很不透徹~
