本文介绍了C#二进制数据转换成字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

下面是这笔交易。我发现了一个源代码,并改变它一点点,所以我可以从一个接收器,是COM6检索数据。这些数据我收到的二进制文件。我想要的是将其转换为字符串,这样我就可以削减部分字符串,并将其单独解码。我怎么能点自己?
的源代码是下面。

 使用系统;使用System.IO.Ports 
;
使用的System.Threading;

公共类PortChat
{
静态布尔_continue;
静态的SerialPort _serialPort;

公共静态无效的主要()
{
字符串名称;
字符串消息;
StringComparer stringComparer = StringComparer.OrdinalIgnoreCase;
螺纹readThread =新主题(读取);

//创建使用默认设置一个新的SerialPort对象。
_serialPort =新的SerialPort();

//允许用户设置相应的属性。
_serialPort.PortName = SetPortName(_serialPort.PortName);
_serialPort.BaudRate = SetPortBaudRate(_serialPort.BaudRate);
_serialPort.Parity = SetPortParity(_serialPort.Parity);
_serialPort.DataBits = SetPortDataBits(_serialPort.DataBits);
_serialPort.StopBits = SetPortStopBits(_serialPort.StopBits);
_serialPort.Handshake = SetPortHandshake(_serialPort.Handshake);

//设置读/写超时
_serialPort.ReadTimeout = 1000;
_serialPort.WriteTimeout = 1000;

_serialPort.Open();
_continue = TRUE;
readThread.Start();

Console.Write(姓名:);
NAME =到Console.ReadLine();

Console.WriteLine(请键入quit退出);

,而(_continue)
{
=消息到Console.ReadLine();

如果(stringComparer.Equals(跳槽,消息))
{
_continue = FALSE;
}
,否则
{
_serialPort.WriteLine(
的String.Format(< {0}计算值:{1},名称,消息)) ;
}
}

readThread.Join();
_serialPort.Close();
}

公共静态无效阅读()
{
,而(_continue)
{


{


字符串消息= _serialPort.ReadLine();
Console.WriteLine(消息);
}
赶上(TimeoutException异常){}
}
}

公共静态字符串SetPortName(字符串defaultPortName)
{
串PORTNAME;

PORTNAME =COM6;

返回PORTNAME;
}

公共静态INT SetPortBaudRate(INT defaultPortBaudRate)
{
串波特率;


波特率=9600;

返回int.Parse(波特率);
}

公共静态奇偶SetPortParity(奇偶defaultPortParity)
{
串奇偶校验;

平价=无;

回报(奇偶校验)Enum.Parse(typeof运算(奇偶校验位),奇偶校验);
}

公共静态INT SetPortDataBits(INT defaultPortDataBits)
{
串数据位;

DATABITS =8;

返回int.Parse(数据位);
}

公共静态停止位SetPortStopBits(停止位defaultPortStopBits)
{
线停止位;

STOPBITS =一;

回报(停止位)Enum.Parse(typeof运算(停止位),停止位);
}

公共静态握手SetPortHandshake(握手defaultPortHandshake)
{
串握手;

握手=无;

回报(握手)Enum.Parse(typeof运算(握手),握手);
}
}


解决方案

数据从端口将二进制(字节)总是,因此它取决于如何解释数据。假设字节是ASCII,您可以在如下编码为一个字符串:

 字节[] binaryData; //假设binaryData包含从端口字节。 

ASCII字符串= Encoding.ASCII.GetString(binaryData);


Here is the deal. I found a source code and changed it a little bit so i can retrieve data from a receiver that is on com6. The data i am receiving is binary. What i want is to convert it to a string so i can cut parts of the string and decode them seperately. how can i dot his? The source code is beneath.

using System;
using System.IO.Ports;
using System.Threading;

public class PortChat
{
    static bool _continue;
    static SerialPort _serialPort;

    public static void Main()
    {
        string name;
        string message;
        StringComparer stringComparer = StringComparer.OrdinalIgnoreCase;
        Thread readThread = new Thread(Read);

        // Create a new SerialPort object with default settings.
        _serialPort = new SerialPort();

        // Allow the user to set the appropriate properties.
        _serialPort.PortName = SetPortName(_serialPort.PortName);
        _serialPort.BaudRate = SetPortBaudRate(_serialPort.BaudRate);
        _serialPort.Parity = SetPortParity(_serialPort.Parity);
        _serialPort.DataBits = SetPortDataBits(_serialPort.DataBits);
        _serialPort.StopBits = SetPortStopBits(_serialPort.StopBits);
        _serialPort.Handshake = SetPortHandshake(_serialPort.Handshake);

        // Set the read/write timeouts
        _serialPort.ReadTimeout = 1000;
        _serialPort.WriteTimeout = 1000;

        _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))
            {
                _continue = false;
            }
            else
            {
                _serialPort.WriteLine(
                    String.Format("<{0}>: {1}", name, message));
            }
        }

        readThread.Join();
        _serialPort.Close();
    }

    public static void Read()
    {
        while (_continue)
        {

            try
            {             


                string message = _serialPort.ReadLine();
                Console.WriteLine(message);
            }
            catch (TimeoutException) { }
        }
    }

    public static string SetPortName(string defaultPortName)
    {
        string portName;

            portName = "COM6";

        return portName;
    }

    public static int SetPortBaudRate(int defaultPortBaudRate)
    {
        string baudRate;


        baudRate = "9600";

        return int.Parse(baudRate);
    }

    public static Parity SetPortParity(Parity defaultPortParity)
    {
        string parity;

        parity = "None";

        return (Parity)Enum.Parse(typeof(Parity), parity);
    }

    public static int SetPortDataBits(int defaultPortDataBits)
    {
        string dataBits;

        dataBits = "8";

        return int.Parse(dataBits);
    }

    public static StopBits SetPortStopBits(StopBits defaultPortStopBits)
    {
        string stopBits;

        stopBits = "One";

        return (StopBits)Enum.Parse(typeof(StopBits), stopBits);
    }

    public static Handshake SetPortHandshake(Handshake defaultPortHandshake)
    {
        string handshake;

        handshake = "None";

        return (Handshake)Enum.Parse(typeof(Handshake), handshake);
    }
}

解决方案

Data from ports will always come in binary(bytes), therefore it depends on how to interpret the data. Assuming that the bytes are ASCII, you can encode it to a string as follows:

byte[] binaryData ; // assuming binaryData contains the bytes from the port.

string ascii =  Encoding.ASCII.GetString(binaryData);
