java 和C# 通过Socket 可以互传hashmap对象吗？

Question

java服务端 和C#客户端 通过Socket和Json序列化互传对象，可以互传hashmap对象吗？如果可以请发下socket的代码，谢谢

该回答引用GPTᴼᴾᴱᴺᴬᴵ以及结合自己思路,具体如下：

是可以通过Socket和Json序列化互传HashMap对象。以下是Java服务端和C#客户端的示例代码：
1、Java服务端代码：

import java.io.*;
import java.net.*;
import java.util.HashMap;
import com.google.gson.Gson;

public class Server {
    private static final int PORT = 8888;

    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(PORT);
            System.out.println("Server started.");

            while (true) {
                Socket socket = serverSocket.accept();
                System.out.println("Client connected.");

                // Read the HashMap object from the client
                InputStream is = socket.getInputStream();
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
                String json = br.readLine();
                Gson gson = new Gson();
                HashMap<String, String> hashMap = gson.fromJson(json, HashMap.class);
                System.out.println("Received HashMap from client: " + hashMap.toString());

                // Send the HashMap object back to the client
                OutputStream os = socket.getOutputStream();
                BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os));
                bw.write(gson.toJson(hashMap));
                bw.newLine();
                bw.flush();

                socket.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

2、C#客户端代码：

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Collections.Generic;
using Newtonsoft.Json;

class Client {
    static void Main(string[] args) {
        try {
            TcpClient tcpClient = new TcpClient("localhost", 8888);
            Console.WriteLine("Connected to server.");

            // Send a HashMap object to the server
            NetworkStream ns = tcpClient.GetStream();
            Dictionary<string, string> hashMap = new Dictionary<string, string>();
            hashMap.Add("name", "John");
            hashMap.Add("age", "30");
            string json = JsonConvert.SerializeObject(hashMap);
            byte[] bytesToSend = Encoding.UTF8.GetBytes(json);
            ns.Write(bytesToSend, 0, bytesToSend.Length);
            ns.Flush();
            Console.WriteLine("Sent HashMap to server: " + json);

            // Receive the HashMap object from the server
            byte[] bytesToRead = new byte[tcpClient.ReceiveBufferSize];
            int bytesRead = ns.Read(bytesToRead, 0, tcpClient.ReceiveBufferSize);
            string receivedJson = Encoding.UTF8.GetString(bytesToRead, 0, bytesRead);
            Dictionary<string, string> receivedHashMap = JsonConvert.DeserializeObject<Dictionary<string, string>>(receivedJson);
            Console.WriteLine("Received HashMap from server: " + receivedJson);

            tcpClient.Close();
        } catch (Exception e) {
            Console.WriteLine("Exception: " + e.ToString());
        }
    }
}
