同步线程? [英] synchronous thread ?

问题描述

我需要使用线程同时按下多个键(内循环)，并在按下一秒钟后重复执行此任务.

我使用此代码，但是如果我使用加入第一个线程而不同时按下，但如果不是同时使用press但所有线程都启动，则会发现一些问题.

I need to use thread to press more than one key at same time (inner loop) and after one second press repeat this task.

I use this code but I found some problem if I use join the first thread not press at same time but if not use press at same time but all thread start.

private void play()
        {
            
            for (int i = 0; i < 2; i++)
            {
                Thread th=null;
                for (int j = 0; j < 2;j++ )
                {
                    
                   SubNote sub= ArrayPlayNote[i].NotesSameTime[j];
             
                   ThreadStart starter = delegate { MessageSub(sub); };
                  th = new Thread(starter);
                
                   th.Start();
                    
                }
                th.Join();
             
            }

        }
///////////////////////////////////////////////////////
Keyboard ky = new Keyboard();
        private void MessageSub( SubNote sub)
        {
            ky.pianoControl1.PressPianoKey(sub.KeyNum);
            Thread.Sleep(1000);
            ky.pianoControl1.ReleasePianoKey(sub.KeyNum);
          
        }

感谢您的帮助.

Thanks for help me.

推荐答案

这是因为总体思路是对线程的严重滥用.一切看起来都是错误的，无法修复.也许如果您解释了该要求，那么某人或我自己会为您提供一个简单的解决方案.这个问题看起来并不困难.


关于通过线程传递参数:请参阅我的解决方案:
如何将ref参数传递给线程 [ ^ ]，
启动后更改线程(生产者)的参数 [ ^ ].

This is because the general idea is such a big misuse of threads. Everything looks wrong and beyond repair. Maybe if you explain the requirement, someone or myself would advise you a simple solution. The problem does not look very difficult.


About passing parameters through thread: see my solutions:
How to pass ref parameter to the thread[^],
change paramters of thread (producer) after it started[^].

—SA

这是基本的

this is the basic

static void Main(string[] args)
       {
           for (int i = 0; i < 100; i++)
           {
               Thread t = new Thread(new ParameterizedThreadStart(MyMethod));
               t.Start(i); //pass in object
           }
           Console.ReadLine();
       }

       public static void MyMethod(object input)
       {
           //Cast object
           Console.WriteLine("Hello from MyMethod " + input.ToString());
       }

因此，您可以将对象传递给线程.如果您需要从控制台到1到99(而不是现在)进行打印，则需要使用ReaderWriterLock.
好吧
如果我错了，请告诉我我正在学习.NET的人.

So you can pass in an object to thread. if you need to print in console from 1 to 99, not like now, you need to use ReaderWriterLock.
Ok.
If I am wrong tell me please someone because i am learning .NET.
