C#编程之C#基础（六）

这里我们讲一下C#编程之线程使用： 线程是程序中独立的指令流。

对于C#和.NET基类为开发多线程应用程序所提供的的支持。线程的使用常用是通过Thread和ThreadPool类来创建与使用。

利用Thread处理线程：

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

namespace ThreadPool
{
    class Program
    {
        static int interval;
        static void Main(string[] args)
        {
            Console.Write("interval to display results at?> ");
            interval = int.Parse(Console.ReadLine());

            Thread thisThread = Thread.CurrentThread;
            thisThread.Name = "CurrentThread";
            ThreadStart workerStart = new ThreadStart(StartMethod);

            Thread workdThread = new Thread(workerStart);
            workdThread.Name = "workThread";
            workdThread.Start();
            DispalyNumbers();
            Console.WriteLine("Main Thread finished.");
            Console.ReadLine();
        }
        static void StartMethod()
        {
            DispalyNumbers();
            Console.WriteLine("worker thread finished.");
        }
        static void DispalyNumbers()
        {
            Thread thisThread = Thread.CurrentThread;
            string name = thisThread.Name;
            Console.WriteLine(name + ": current culture= " + thisThread.CurrentCulture);
            for (int i = 1; i < 8 * interval; i++)
            {
                if(i%interval==0)
                {
                    Console.WriteLine(name + ":count has reached " + i);
                }
            }
        }
    }
}

运行输入数字：

如下利用ThreadPool类创建线程：

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

namespace ThreadDemo
{
    class Program
    {
        static int interval;
        static void Main(string[] args)
        {
            Console.Write("interval to display results at?>");
            interval = int.Parse(Console.ReadLine());
            ThreadPool.QueueUserWorkItem(new WaitCallback(StartMethod));
            Thread.Sleep(100);
            ThreadPool.QueueUserWorkItem(new WaitCallback(StartMethod));
            Console.ReadLine();
        }
        static void StartMethod(object stateInfo)
        {
            //todo your code here
            DisplayNumbers("Thread " + DateTime.Now.Millisecond.ToString());
            Console.WriteLine("Thread Finished.");
        }
        static void DisplayNumbers(string GivenThreadName)
        {
            Console.WriteLine("Start thread: " + GivenThreadName);
            for(int i=1;i<8*interval;i++)
            {
                Console.WriteLine("Count has reached: " + i);
                Thread.Sleep(1000);
            }
        }
    }
}
