套接字通信协议 [英] Socket Communication Protocol

问题描述

创建通信协议的最佳方法是什么?
我需要发送命令，每个命令都将匹配某些参数.
接收方将根据命令执行某些操作.
我看过的所有示例仅发送字符串，我需要更强大的功能，所以我应该使用什么:类，结构，字典，枚举，数组?
关于什么是最佳方法有什么建议吗?


我正在使用System.Net.Sockets.TcpListener和System.Net.Sockets.TcpClient
我只想知道如何才能动态地创建和发送消息

What is the best way to create a communication protocol?
I need to send commands, each command will match certain parameters.
the receiver will do some action based on command.
All the examples i''ve seen send only string, i need something more powerfull so what should i use: class, struct, dictionary, enum, array?
Any suggestions on what the best approach?


I''m using System.Net.Sockets.TcpListener and System.Net.Sockets.TcpClient
I want only to know how i can dinamically create and send my messages

推荐答案

我认为最通用的解决方案是

I think the most versatile solution is Windows Communication Foundation[^].
But it depends on how complex the solution is. More simple solutions is just to exchange a XML document.

您可以使用多个级别.

请在我概述它们的地方查看我过去的答案:
如何将byte []发送到另一台PC [ ^ ]，
在局域网上与两个Windows应用程序进行通信. [ ^ ].

最适合您的取决于您的要求.

There are several levels you can use.

Please see my past answer where I overview them:
how i can send byte[] to other pc[^],
Communication b/w two Windows applications on LAN.[^].

What''s the best for you really depends on your requirements.

Morph King，

它实际上取决于您将在应用程序中使用的协议.

对于 Tcp客户端协议，您可以编写以下类:

Hi Morph King,

it actually depends on the protocol which you will use in your application.

For Tcp Client Protocol you may write a class as below:

class Connection
{
    // Connection variable
    private TcpClient Connection { get; set; }

    // Network communication.
    private NetworkStream ns { get; set; }

    // Connection is done or not.
    public bool isConnection{ get; set; }

    // Buffer for receiving/sending bytes.
    private byte[] BytesToSend, bytesReceived;

    // Connection constructor.
    public Baglanti(string hostname, string port)
    {
        // Take IP adress ve Port number.
        // Make a connection.
        baglanti = new TcpClient(hostname, int.Parse(port));

        if (baglanti.Connected) // if connected.
        {
            ByteReceived= new byte[baglanti.ReceiveBufferSize];
            ns = Connection.GetStream();

            isConnection = true;
        }
    }

    // Method for connection
    public bool Baglan(string hostname, string port)
    {
        // if is Connected.
        if (isConnection)
            return isConnection;
        // Test Connection
        try
        {
            Connection = new TcpClient(hostname, int.Parse(port));
            if (Connection.Connected)
            {
                ByteReceived = new byte[Connection.ReceiveBufferSize];
                ns = Connection.GetStream();
                isConnection = true;
                return true;
            }
        }
        // if no connection
        catch (Exception)
        {
           isConnection = false;
        }
        return isConnection;
    }

    // Cut off the Connection
    public void CutOffConnection()
    {
        ns.Close();
        Connection.Close();
        isConnection = false;
    }

    // Sending Data
    public bool SendData(string s)
    {
        if (!Connection.Connected)
        {
            isConnection = false;
            return false;
        }
        try
        {
            BytesToSend = System.Text.Encoding.ASCII.GetBytes(s);
            ns.Write(BytesToSend, 0, BytesToSend.Length);
            ns.Flush();
            return true;
        }
        catch (Exception)
        {
            baglantivar = false;
            return false;
        }
    }

    // Getting Data
    public bool GetData(ref string ServerResponse)
    {
        if (!isConnection.Connected)
        {
            isConnection = false;
            return false;
        }
        try
        {
            ns.Read(ByteReceived, 0, Conneciton.ReceiveBufferSize);
            ServerResponse = System.Text.Encoding.ASCII.GetString(ByteReceived );
            return true;
        }
        catch (Exception)
        {
            isConnection = false;
            return false;
        }
    }
}

另一个问题:
您要与电子设备(例如pic，dsPic)或计算机主机通信吗?

One more question:
Are you going to communicate with an electronic device (such as pic, dsPic) or a computer Host?
