多个插座连接 [英] Multiple socket connection

问题描述

您好，



我有6台设备，价格检查器。我有一个项目，超市的客户将扫描此设备上的产品，它将返回产品的价格。我已设法连接一台设备，获取条形码并发送数据。但我似乎无法连接多个插座连接。

这是我收到和发送数据时的代码：



连接使用该设备：

 私人 无效 connect1（ string  adip， int  porta）
 {
  try  
 {
 IPEndPoint ip =  new  IPEndPoint（IPAddress.Parse（adip），porta）; 
 connect1 =  new  Socket（AddressFamily.InterNetwork，SocketType.Stream，ProtocolType.Tcp）; 
 connect1.Connect（ip）; 
} 
  catch （System.Net.Sockets.SocketException se）
 {
 MessageBox.Show（se.Message） ）; 
} 
} 

获取条形码：

 私有  void  getbarCode（）
 {
  byte  [] data =  new   byte  [ 1024 ]; 
  int  receivedDataLength = lidhje.Receive（data）; 
 numberCodeBar = Encoding.ASCII.GetString（data， 0 ，receivedDataLength）; 
} 

向设备发送数据：

< pre lang =cs> private void sendData（ string price1）
{
尝试
{
对象 objData = price1;
byte [] price = System.Text.Encoding.ASCII.GetBytes（objData.ToString（））;

connect1.Send（price）;
}
catch （System.Net.Sockets.SocketException se）
{
MessageBox.Show（se.Message） ）;
}
}

我想在同一时间使用muliple decives进行此操作。我搜索了谷歌，但没有运气。

解决方案

我建​​议写一个代理服务/消息队列，它将以异步方式从设备收集产品扫描结果，然后将其提取到价格服务以返回适当的产品价格。

Hello,

I have 6 devices, price checkers. I have a project which the client in a supermarket will scan a product on this device and it will return the price of the product. I have managed to connect with one device, get the bar code and send data. But I can not seem to do to connect with multiple socket connection.
This is the code when I receive and send data:

Connecting with the device:

private void connect1(string adip, int porta)
        {
            try
            {
                IPEndPoint ip = new IPEndPoint(IPAddress.Parse(adip), porta);
                connect1 = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                connect1.Connect(ip);
            }
            catch (System.Net.Sockets.SocketException se)
            {
                MessageBox.Show(se.Message);
            }
        }

Getting the barcode:

private void getbarCode()
        {
            byte[] data = new byte[1024];
            int receivedDataLength = lidhje.Receive(data);
            numberCodeBar = Encoding.ASCII.GetString(data, 0, receivedDataLength);
        }

Sending data to device:

private void sendData(string price1)
        {
            try
            {
                Object objData = price1;
                byte[] price = System.Text.Encoding.ASCII.GetBytes(objData.ToString());

                connect1.Send(price);
            }
            catch (System.Net.Sockets.SocketException se)
            {
                MessageBox.Show(se.Message);
            }
        }

I want to make this with muliple decives in the same time. I have searched Google but no luck.

解决方案

I would suggest to write down one broker service/ message queue which will collect product scan results from the devices in async manner and then fetch it to the price service to return appropriate price of product.
