3.1 Import package dependecies

Open Program.cs and add to head

using System;
using System.Threading;
using com.tvd12.ezyfoxserver.client;
using com.tvd12.ezyfoxserver.client.io;
using com.tvd12.ezyfoxserver.client.evt;
using com.tvd12.ezyfoxserver.client.request;
using com.tvd12.ezyfoxserver.client.config;
using com.tvd12.ezyfoxserver.client.setup;
using com.tvd12.ezyfoxserver.client.handler;
using com.tvd12.ezyfoxserver.client.constant;
using com.tvd12.ezyfoxserver.client.entity;
using com.tvd12.ezyfoxserver.client.factory;

3.2 Create a client

EzyClientConfig clientConfig = EzyClientConfig
                .builder()
                .clientName("first")
                .zoneName("example")
                .build();
EzyClients clients = EzyClients.getInstance();
EzyClient client = clients.newDefaultClient(clientConfig);

3.3 Setup the client

EzySetup setup = client.setup();
setup.addEventHandler(EzyEventType.CONNECTION_SUCCESS, new EzyConnectionSuccessHandler());
setup.addEventHandler(EzyEventType.CONNECTION_FAILURE, new EzyConnectionFailureHandler());
setup.addDataHandler(EzyCommand.HANDSHAKE, new ExHandshakeEventHandler());
setup.addDataHandler(EzyCommand.LOGIN, new ExLoginSuccessHandler());
setup.addDataHandler(EzyCommand.APP_ACCESS, new ExAccessAppHandler());

3.4 Setup an app

EzyAppSetup appSetup = setup.setupApp("hello-world");
appSetup.addDataHandler("broadcastMessage", new MessageResponseHandler());

3.5 Connect to server

client.connect("localhost", 3005);

3.6 Loop socket events

while (true) 
{
    Thread.Sleep(3);
    client.processEvents();
}

3.7 Create event and data handler classes

class ExHandshakeEventHandler : EzyHandshakeHandler
{
    protected override EzyRequest getLoginRequest()
    {
        return new EzyLoginRequest("example", "monkey", "123456");
    }
}

class ExLoginSuccessHandler : EzyLoginSuccessHandler
{
    protected override void handleLoginSuccess(EzyData responseData)
    {
        EzyRequest accessAppRequest = new EzyAppAccessRequest("hello-world");
        client.send(accessAppRequest);
    }
}

class ExAccessAppHandler : EzyAppAccessHandler
{
    protected override void postHandle(EzyApp app, EzyArray data)
    {
        broadcastMessage(app);
    }

    protected void broadcastMessage(EzyApp app)
    {
        EzyObject data = EzyEntityFactory.newObjectBuilder()
            .append("message", "hello everyone!")
            .build();
        app.send("broadcastMessage", data);
    }
}

class MessageResponseHandler : EzyAppDataHandler
{
    public void handle(EzyApp app, EzyData data)
    {
        EzyObject obj = (EzyObject)data;
        String message = obj.get<String>("message");
        Console.WriteLine("Received message: " + message);
    }
}

After all, we have the Program.cs with full content:

using System;
using System.Threading;
using com.tvd12.ezyfoxserver.client;
using com.tvd12.ezyfoxserver.client.io;
using com.tvd12.ezyfoxserver.client.evt;
using com.tvd12.ezyfoxserver.client.request;
using com.tvd12.ezyfoxserver.client.config;
using com.tvd12.ezyfoxserver.client.setup;
using com.tvd12.ezyfoxserver.client.handler;
using com.tvd12.ezyfoxserver.client.constant;
using com.tvd12.ezyfoxserver.client.entity;
using com.tvd12.ezyfoxserver.client.factory;

namespace HelloWorld
{
    class ExHandshakeEventHandler : EzyHandshakeHandler
    {
        protected override EzyRequest getLoginRequest()
        {
            return new EzyLoginRequest("example", "monkey", "123456");
        }
    }

    class ExLoginSuccessHandler : EzyLoginSuccessHandler
    {
        protected override void handleLoginSuccess(EzyData responseData)
        {
            EzyRequest accessAppRequest = new EzyAppAccessRequest("hello-world");
            client.send(accessAppRequest);
        }
    }

    class ExAccessAppHandler : EzyAppAccessHandler
    {
        protected override void postHandle(EzyApp app, EzyArray data)
        {
            broadcastMessage(app);
        }

        protected void broadcastMessage(EzyApp app)
        {
            EzyObject data = EzyEntityFactory.newObjectBuilder()
                .append("message", "hello everyone!")
                .build();
            app.send("broadcastMessage", data);
        }
    }

    class MessageResponseHandler : EzyAppDataHandler
    {
        public void handle(EzyApp app, EzyData data)
        {
            EzyObject obj = (EzyObject)data;
            String message = obj.get<String>("message");
            Console.WriteLine("Received message: " + message);
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            EzyClientConfig clientConfig = EzyClientConfig
                .builder()
                .clientName("first")
                .zoneName("example")
                .build();
            EzyClients clients = EzyClients.getInstance();
            EzyClient client = clients.newDefaultClient(clientConfig);

            EzySetup setup = client.setup();
            setup.addEventHandler(EzyEventType.CONNECTION_SUCCESS, new EzyConnectionSuccessHandler());
            setup.addEventHandler(EzyEventType.CONNECTION_FAILURE, new EzyConnectionFailureHandler());
            setup.addDataHandler(EzyCommand.HANDSHAKE, new ExHandshakeEventHandler());
            setup.addDataHandler(EzyCommand.LOGIN, new ExLoginSuccessHandler());
            setup.addDataHandler(EzyCommand.APP_ACCESS, new ExAccessAppHandler());

            EzyAppSetup appSetup = setup.setupApp("hello-world");
            appSetup.addDataHandler("broadcastMessage", new MessageResponseHandler());

            client.connect("localhost", 3005);

            while (true)
            {
                Thread.Sleep(3);
                client.processEvents();
            }
        }
    }
}

Now, click run and you can see the result:
