Question

我想建立一个聊天！现在我的目标是接收来自用户的输入（将被提供给类中的函数），保存并通过网络将对象发送给用户。

到目前为止，这是我的代码：

namespace ConsoleApplication1
{
    class Program
    {       
        static void Main(string[] args)
        {
            TcpListener server = new TcpListener(IPAddress.Any, 5000);
            server.Start();
            Console.WriteLine("Server started");
            int a = 0;

            while (true)
            {
                TcpClient connection = server.AcceptTcpClient();
                Console.WriteLine("connection accepted");

                ThreadPool.QueueUserWorkItem(ProssecClient, connection);
            }
        }

        public static void ProssecClient(object o)
        {
            TcpClient connection = o as TcpClient;
            if (connection == null)
                return;
            StreamReader sr = new StreamReader(connection.GetStream());
            StreamWriter sw = new StreamWriter(connection.GetStream());
            string word = "";
            savedObject saved = new savedObject();

            try
            {
                while (true)
                {
                    sw.WriteLine(sr.ReadLine());
                    sw.Flush();

                    // here the server should read and retrieve, 
                    // everything that it gets to every user that logs in.
                }
            }
            catch
            { 
                Console.WriteLine("client left");
            }
        }           
    }
}

我将所有内容保存在binaryFormatter中，如何将其发送给用户接收？

客户端代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;
using System.IO;
using System.Threading;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpClient connection = new TcpClient("127.0.0.1", 5000);
            StreamReader sr = new StreamReader(connection.GetStream());
            StreamWriter sw = new StreamWriter(connection.GetStream());
            savedObject saved = new savedObject();
            Stream stream = File.Open("EmployeeInfo.osl", FileMode.Create);
            BinaryFormatter bformatter = new BinaryFormatter();
            string word = "";
            string allwords = "";

            Thread Listen = new Thread(deserialise);
            Listen.Start();

            while (true)
            {
                word = Console.ReadLine();
                allwords = saved.AllWords(word);
                sw.WriteLine(allwords);
                sw.Flush();
                Console.WriteLine(sr.ReadLine());

                //Serialize
                //bformatter.Serialize(stream, saved);
                //stream.Close();

                //sw.WriteLine(saved);
            }
        }
    }

    public static void deserialise()
    {
        //Deserialize
        //if (File.Exists("EmployeeInfo.osl"))
        //{
        //    stream = File.Open("EmployeeInfo.osl", FileMode.Open);
        //    bformatter = new BinaryFormatter();

        //    saved = (savedObject)bformatter.Deserialize(stream);
        //    stream.Close();
        //}

    }
}

[Serializable()]
class savedObject : ISerializable
{
    public string allwords;

    public string AllWords(string words)
    {
        allwords += words + " ";
        return allwords;
    }

    public void Words(SerializationInfo info, StreamingContext ctxt)
    {
        info.AddValue("RetrievedWord", allwords);
    }


    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        allwords = (String)info.GetValue("RetrievedWord", typeof(string));
    }
}

Answer 1

考虑WCF。

从一致的高层视角处理所有通信问题，包括安全性，不同协议等。

它几乎是.Net中通信的标准，涵盖并取代了较旧的更低级别的技术。

Answer 2

在ProcessClient方法中：

TcpClient client = (TcpClient) connection;

using(StreamWriter streamWriter = new StreamWriter(tcpClient.GetStream()))
{
    BinaryFormatter binaryFormatter = new BinaryFormatter();
    binaryFormatter.Serialize(streamWriter, savedObject);
}

Answer 3

您可以使用SOAP架构（使用XML序列化而不是二进制序列化），它实现起来会更容易。或者，如果您需要点对点聊天code here。
