c#多线程编程笔记1

 

[myElement]表示变量

 

第一部分   线程的概念

第二部分   线程的基本用法

 

第一步：引入命名空间：using System.Threading;

第二步：申明ThreadStart（即线程的入口）;语法格式如下:

ThreadStart myThreadStart=new ThreadStart([method])；

第三步：定义一个线程；语法格式如下：

Thread [threadOne]=new Thread([ThreadStart]);

[ThreadStart]必须定义好！

第四步：执行线程，语法格式如下:

[Thread].Start();

 

其它语法：

挂起线程：表示处理器不再需要安排这个线程的执行。[workerThread].Suspend();

休眠进程：表示暂停[wokerThread].Sleep([time]);

联接线程：将使调用线程进入WaitSleepJoin状态，然后调用线程将阻塞，直到另一个线程实例终止。[worker].Join();

例子1：

using System;

using System.Collections.Generic;

using System.Text;

using System.Threading;//引入这个命名空间

 

namespace ConsoleApplication1

{

    class Program1

    {

        static void main(string[] args)

        {

            Console.WriteLine("{Main Thread} Creating the thread start delegate.");

            ThreadStart workerThreadStart = new ThreadStart(SimpleWorkerThread);//定义一//个线程入口为SimpleWorkerThread.

            Console.WriteLine("{Main Thread} Creating the worker thread.");

            Thread workerThread = new Thread(workerThreadStart);//定义一个线程，线程名为workerThread

            //线程开始

            workerThread.Start();

            Console.Read();

            //线程的非正常结束

            workerThread.Abort();

            Console.WriteLine("{Main Thread} Aborting worker thread.");

            workerThread.Join();

            Console.WriteLine("{Main Thread} Worker Thread Terminated.");

            Console.Read();

 

        }

        public static void SimpleWorkerThread()

        {

            for (int i = 0; ; i++)

            {

                try

                {

                    Console.WriteLine("Hello from the worker thread.");

                    if (i > 1000)

                    {

                        Thread.CurrentThread.Abort();

                        return;

                    }

                }

                catch (Exception e)

                {

                    Console.WriteLine(e.ToString()+" Exception caught.");

                    Thread.ResetAbort();

                }

            }

 

        }

    }

}
