无法知道serialport程序中的错误 [英] Could not know error in serialport program

问题描述

hellow

在以下2个程序中我从msdn.i获得它的主要部分试图让它有两个路径（读写）我的意思是计算机A中的第一个程序（发送）和计算机B中的下一个程序（接收）经过多次尝试它工作正常然后我开始改进它（我的意思是将一些变量从全局更改为本地）但我在接收程序中出错，我想我的错误是如何声明变量

name，message，_continue和stringComparer。它们应该是全球性的还是静态的......

这样的东西

编程串口难以想象并难以遵循其流程图

i我已尽全力

需要你的帮助

非常感谢



我有什么试过：

hellow
in the following 2 programs which i have got the main part of it from msdn.i tried to have it two path (read and write ) i mean 1st program in computer A (sending)and the next program (receiving ) in computer B. after many tries it was working fine then i begin to improve it (i mean to change some variable from global to local) but i got errors in the receiving program , i guess my error is how to declare the variables
name,message,_continue,and stringComparer. should they be global and static ....
something like this
programming serial port is difficult to imagine and hard to follow its flowchart
i have given it all i can
needs your fine help
many thanks

What I have tried:

        static SerialPort _serialPort = new SerialPort();
        static bool _continue = true;
        //static StringComparer stringComparer = StringComparer.OrdinalIgnoreCase;
        public static void Main(string[] args)
        {
            string name;
            string message;
            StringComparer stringComparer = StringComparer.OrdinalIgnoreCase;
            Thread readThread = new Thread(Read);
//serial port setting =com1,9600,Parity.None,8,StopBits.One,Handshake.Nonereadtimeout=500,wrtetimeout=500
            _serialPort.Open();
            _continue = true;
            readThread.Start();
            Console.Write("Name: ");
            name = Console.ReadLine();
            Console.WriteLine("Type QUIT to exit");
            while (_continue)
            {
                message = Console.ReadLine();
                if (stringComparer.Equals("quit", message))
                {
                    _serialPort.WriteLine(String.Format("<{0}>: {1}", name, message));
                    _continue = false;
                }
                else
            _serialPort.WriteLine( String.Format("<{0}>: {1}", name, message) );
                  }//while

                    Console.WriteLine(String.Format("<{0}>: {1}", name, message));
                    if (stringComparer.Equals("quit", message))
                    {
                        _continue = false;

//我猜电缆不好（有些电线似乎连接但实际上没有）这迫使我责怪一个nd修改代码。这里的代码最终运行没有任何错误，抱歉错误

// i guess the cable was not good ( some wires were seems it is connected but actually not )which force me to blame and modify the code. here the code which finally run without any error ,sorry for the mistake
