多线程之可以自定义的线程池-优快云博客

本文介绍了一个使用C#实现的线程池类WorkBackground，该类能够限制同时运行的线程数量，通过委托调用后台方法处理任务，并提供等待所有任务完成的方法。通过实例演示了如何使用该类开启50个线程处理任务列表。

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

namespace JdLibrary.Com
{
    public class WorkBackground
    {
        public delegate void BackgroundMethod(params object[] objs);
        private int threadCount = 0;
        private int MaxThreadCount = 0;

        public WorkBackground(int maxThreadCount)
        {
            MaxThreadCount = maxThreadCount;
        }

        public void Run(BackgroundMethod backgroundMethod, params object[] objs)
        {
            while (threadCount >= MaxThreadCount)
            { Thread.Sleep(5); }

            lock (this) { threadCount++; }

            Thread thread = new Thread((object threadObj) =>
            {
                if (threadObj as object[] != null)
                { backgroundMethod(threadObj as object[]); }
                else
                { backgroundMethod(); }

                lock (this) { threadCount--; }
            });
            thread.IsBackground = true;
            thread.Start(objs);
        }

        public void WaitComplete()
        {
            while (threadCount > 0)
            { Thread.Sleep(5); }
        }
    }
}

　　调用方式开启50个线程去处理

var backWork = new JdLibrary.Com.WorkBackground(50);
foreach (var item in list)
{
backWork.Run(delegate
{
UpdateStation(item, cpid);//调用的方法，或者代码
});
}
backWork.WaitComplete();
