Custom Serialization

Demonstrates sending complex objects using your preferred serializer (e.g., JSON), carried as strings or byte arrays.

Scenario

You want to send DTOs rather than only primitive types.

Code Example

using System;
using System.Collections.Generic;
using System.Text;
using Newtonsoft.Json;
using SocketMeister;

public class MyDto { public int Id { get; set; } public string Name { get; set; } }

// Server
var server = new SocketServer(port: 5003, CompressSentData: false);
server.MessageReceived += (s, e) =>
{
    // Expect JSON string in parameter[0]
    string json = (string)e.Parameters[0];
    var dto = JsonConvert.DeserializeObject<MyDto>(json);

    // Process and return a JSON reply
    dto.Name = dto.Name + "_ACK";
    string replyJson = JsonConvert.SerializeObject(dto);
    e.Response = Encoding.UTF8.GetBytes(replyJson);
};
server.Start();

// Client
var client = new SocketClient(new List<SocketEndPoint> { new SocketEndPoint("localhost", 5003) }, EnableCompression: false, friendlyName: "CustomSerClient");
client.Start();

var outgoing = new MyDto { Id = 42, Name = "Foobar" };
string payload = JsonConvert.SerializeObject(outgoing);

byte[] bytes = client.SendMessage(new object[] { payload }, TimeoutMilliseconds: 5000);
string replyJson = Encoding.UTF8.GetString(bytes);
var responseDto = JsonConvert.DeserializeObject<MyDto>(replyJson);

Console.WriteLine($"Received DTO with Name={responseDto.Name}");

client.Stop();
server.Stop();

Notes:

• SocketMeister serializes message parameters (e.g., string, int, byte[]) automatically. For custom object graphs, serialize to string or byte[] yourself.
• Consider enabling compression for large JSON payloads.
