多线程/在C＃中同时运行2个线程 [英] Multithreading / Running 2 threads simultaneously in C#

问题描述

我对多线程有一些困惑，关于它如何运行。



这是我的代码。

使用System; 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.Text; 
使用System.Threading; 
 
 namespace MultiThreading 
 {
 class program 
 {
 static void Main（string [] args）
 {
 Operations op = new Operations（）; 
线程Th1 =新线程（新的ThreadStart（op.Op1））; 
线程Th2 =新线程（新的ThreadStart（op.Op2））; 
 //线程Th3 =新线程（新的ThreadStart（op.Op3））; 
 Th1.Start（）; 
 Th2.Start（）; 
 //Th3.Start（）; 
 Console.ReadLine（）; 
} 
} 
 class操作
 {
 public void Op1（）
 {
 Console.WriteLine（线程1操作A） ; 
 Thread.Sleep（2000）; 
 Op3（）; 
 Console.WriteLine（线程1操作B）; 
 Thread.Sleep（2000）; 
 Op3（）; 
 Console.WriteLine（线程1操作C）; 
} 
 public void Op2（）
 {
 Console.WriteLine（Thread 2 operation A）; 
 Thread.Sleep（2000）; 
 Console.WriteLine（线程2操作B）; 
 Thread.Sleep（2000）; 
 Console.WriteLine（线程2操作C）; 
} 
 public void Op3（）
 {
 Console.WriteLine（Do Nothing）; 
} 
} 
} 

我得到的输出是

线程1操作A 
线程2操作A 
线程2操作B 
什么都不做
线程1操作B 
什么都不做
线程1操作C 
线程2操作C 

然而，下一次我跑，我得到了不同的输出。任何人都可以解释为什么会发生这种情况



编辑：

如果是正常的并且调度算法决定运行哪个，那么以何种方式我可以控制线程使输出以我想要的格式显示？

解决方案

它是normal.it是调度算法谁决定运行

I am having some confusions regarding multithreading, and regarding how it runs.

This is my code.

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

namespace MultiThreading
{
    class Program
    {
        static void Main(string[] args)
        {
            Operations op = new Operations();
            Thread Th1 = new Thread(new ThreadStart(op.Op1));
            Thread Th2 = new Thread(new ThreadStart(op.Op2));
            //Thread Th3 = new Thread(new ThreadStart(op.Op3));
            Th1.Start();
            Th2.Start();
            //Th3.Start();
            Console.ReadLine();
        }
    }
    class Operations
    {
        public void Op1()
        {
            Console.WriteLine("Thread 1 operation A");
            Thread.Sleep(2000);
            Op3();
            Console.WriteLine("Thread 1 operation B");
            Thread.Sleep(2000);
            Op3();
            Console.WriteLine("Thread 1 operation C");
        }
        public void Op2()
        {
            Console.WriteLine("Thread 2 operation A");
            Thread.Sleep(2000);
            Console.WriteLine("Thread 2 operation B");
            Thread.Sleep(2000);
            Console.WriteLine("Thread 2 operation C");
        }
        public void Op3()
        {
            Console.WriteLine("Do Nothing");
        }
    }
}

The output I get is

Thread 1 operation A
Thread 2 operation A
Thread 2 operation B
Do Nothing
Thread 1 operation B
Do Nothing
Thread 1 operation C
Thread 2 operation C

However, the very next time I run, I get a varying outputs. Can anyone explain why this happens

EDIT:
If it is normal and it is the Scheduling Algorithm who decides which to run, is there any way I can control the threads to make the output appear in a format that I want ?

解决方案

it is normal.it is the Scheduling Algorithm who decides which to run.
