Singleton是我学的第一个模式，看了博客园上的解释，有点小问题。改了之后贴上。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

namespace Singleton
{
    public class CountSigleton
    {
        /**////存储唯一的实例
        static CountSigleton uniCounter = new CountSigleton();

        /**////存储计数值
        private int totNum = 0;

        private CountSigleton()

        {
            /**////线程延迟2000毫秒
            Thread.Sleep(2000);
        }

        static public CountSigleton Instance()

        {

            return uniCounter;

        }

        /**////计数加1
        public void Add()
        {
            totNum ++;
        }

        /**////获得当前计数值
        public int GetCounter()
        {
            return totNum;
        }

    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

namespace Singleton
{
    public class CountMutilThread
    {
        public CountMutilThread()
        {

        }

        /**//// <summary>
        /// 线程工作
        /// </summary>
        public static void DoSomeWork()
        {
            /**////构造显示字符串
            string results = "";

/**////创建一个Sigleton实例
CountSigleton MyCounter = CountSigleton.Instance();

            /**////循环调用四次
            for(int i=1;i<5;i++)
            {
                /**////开始计数
                lock (MyCounter)
                {

MyCounter.Add();

                    results += "线程";
                    results += Thread.CurrentThread.Name.ToString() + "——〉";
                    results += "当前的计数：";
                    results += MyCounter.GetCounter().ToString();
                    results += "/n";

Console.WriteLine(results);

                    /**/
                    ///清空显示字符串
                    results = "";
                }
            }
        }

public void StartMain()
{

            Thread thread0 = Thread.CurrentThread;

            thread0.Name = "Thread 0";

            Thread thread1 =new Thread(new ThreadStart(DoSomeWork));

            thread1.Name = "Thread 1";

            Thread thread2 =new Thread(new ThreadStart(DoSomeWork));

            thread2.Name = "Thread 2";

            Thread thread3 =new Thread(new ThreadStart(DoSomeWork));

            thread3.Name = "Thread 3";

            thread1.Start();

            thread2.Start();

            thread3.Start();

            /**////线程0也只执行和其他线程相同的工作
            DoSomeWork();
        }
    }

}

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

namespace Singleton
{
    public class CountClient
    {
        public static void Main(string[] args)
        {
       CountMutilThread cmt = new CountMutilThread();

            cmt.StartMain();

            Console.ReadLine();
        }
    }
