生產者消費者問題（C#）

標籤：c#   生產者   消費者   

生產者類：

 

public class Producer
{

    ArrayList container = null;

 

    //得到一個容器

    public Producer(ArrayList container)
    {

        this.container = container;

    }

 

    //定義一個生產物品的方法裝入容器

    public void Product(string name)
    {

        //建立一個新物品裝入容器

        Goods goods = new Goods();

        goods.Name = name;

        this.container.Add(goods);

 

        Console.WriteLine("生產了物品：" + goods.ToString());

    }

}

 

 

消費者類：

 

 

public void Consumption()
    {

        Goods goods = (Goods)this.container[0];

 

        Console.WriteLine("消費了物品：" + goods.ToString());

 

        //消費掉容器中的一個物品

        this.container.RemoveAt(0);

    }

}

 

食物類：

 

 

public class Goods
{

    //物品名稱

    private string name;

 

    public string Name
    {

        get { return name; }

        set { name = value; }

    }

    //重寫ToString()

    public override string ToString()
    {

        return "物品名稱：" + name;

    }

}

 

 

主程式：

 

 

using System;
using System.Collections.Generic;
using System.Text;

using System.Threading;
namespace ConsoleApplication1
{
    class Program
    {

        {

            Program p = new Program();

            //建立兩個線程並啟動

            Thread t1 = new Thread(new ThreadStart(p.ThreadProduct));
            Thread t2 = new Thread(new ThreadStart(p.ThreadConsumption));
            t1.Start();
            //t1.Sleep(1);
            t2.Start();

            Console.Read();

        }

        //定義一個線程方法生產8個物品

        public void ThreadProduct()
        {
            //建立一個生產者
            producer = new Producer(this.container);
            lock (this)  //防止因爭奪資源而造成互相等待           {
                for (int i = 1; i <= 8; i++)
                {

                    //如果容器中沒有就進行生產

                    if (this.container.Count == 0)
                    {
                        //調用方法進行生產
                        producer.Product(i + "");
                        //生產好了一個通知消費者消費
                        Monitor.Pulse(this);
                    }

                    //容器中還有物品等待消費者消費後再生
                    Monitor.Wait(this);
                }
            }
        }

        //定義一個線程方法消費生產的物品

        public void ThreadConsumption()
        {

            //建立一個消費者

            consumer = new Consumer(this.container);

            lock (this)//防止因爭奪資源而造成互相等待               {

                while (true)
                {

                    //如果容器中有商品就進行消費

                    if (this.container.Count != 0)
                    {

                        //調用方法進行消費

                        consumer.Consumption();

                        Monitor.Pulse(this);

                    }

                    //容器中沒有商品通知消費者消費

                    Monitor.Wait(this);

                }

            }

        }
    }
