本文实例讲述了C#使用 Parallel 类进行多线程编程的方法。分享给大家供大家参考。具体如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Diagnostics;
using System.Runtime.InteropServices;
namespace Threads
{
class Program
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern int GetCurrentProcessorNumber();
private static int criticalSection = 0;
private static object lockObject = new object();
static void Main(string[] args)
{
Console.WriteLine("==================Sequential calls==============");
Console.WriteLine();
Target();
Target();
Target();
Target();
Target();
Target();
Target();
Target();
Console.WriteLine();
Console.WriteLine("==================Parallel calls==============");
Console.WriteLine();
Action action = new Action(Target);
Parallel.Invoke(new Action[] { action, action, action, action, action, action, action, action });
Console.ReadKey();
}
private static void Target()
{
Thread.Sleep(2000);
lock (lockObject)
{
criticalSection++;
Console.WriteLine(string.Format("Thread ID: {0} and Processor ID: " +
"{1} Critical Variable Value: {2}",
Thread.CurrentThread.ManagedThreadId,
GetCurrentProcessorNumber(), criticalSection));
}
}
}
}
