Description

-----------

Create instance of `Socket` class by passing url of socketcluster-server end-point



```C#

    //Create a socket instance

    string url = "ws://localhost:8000/socketcluster/";

    var socket = new Socket(url);



```

**Important Note** : Default url to socketcluster end-point is always *ws://somedomainname.com/socketcluster/*.



#### Registering basic listeners



Create a class implementing `BasicListener` interface and pass it's instance to socket setListener method



```C#



        internal class MyListener : IBasicListener

        {

            public void OnConnected(Socket socket)

            {

                Console.WriteLine("connected got called");

            }



            public void OnDisconnected(Socket socket)

            {

                Console.WriteLine("disconnected got called");

            }



            public void OnConnectError(Socket socket, ErrorEventArgs e)

            {

                Console.WriteLine("on connect error got called");

            }



            public void OnAuthentication(Socket socket, bool status)

            {

                Console.WriteLine(status ? "Socket is authenticated" : "Socket is not authenticated");

            }



            public void OnSetAuthToken(string token, Socket socket)

            {

                socket.setAuthToken(token);

                Console.WriteLine("on set auth token got called");

            }



        }



        internal class Program

        {

            public static void Main(string[] args)

            {

                var socket = new Socket("ws://localhost:8000/socketcluster/");

                socket.SetListerner(new MyListener());

            }

        }



```



#### Connecting to server



- For connecting to server:



```C#

    //This will send websocket handshake request to socketcluster-server

    socket.Connect();

```



- By default reconnection to server is not enabled , to enable it :



```C#

    //This will set automatic-reconnection to server with delay of 3 seconds and repeating it for 30 times

    socket.SetReconnectStrategy(new ReconnectStrategy().SetMaxAttempts(30));

    socket.Connect()

```



- To disable reconnection :



```

   socket.SetReconnectStrategy(null);

```



Emitting and listening to events

--------------------------------

#### Event emitter



- eventname is name of event and message can be String, boolean, Long or JSON-object



```C#

    socket.Emit(eventname,message);



    //socket.Emit("chat","Hi");

```



- To send event with acknowledgement



```C#



    socket.Emit("chat", "Hi", (eventName, error, data) =>

    {

       //If error and data is String

       Console.WriteLine("Got message for :"+eventName+" error is :"+error+" data is :"+data);

    });



```



#### Event Listener



- For listening to events :



The object received can be String, Boolean, Long or JSONObject.



```C#



    socket.On("chat", (eventName, data) =>

    {

        Console.WriteLine("got message "+ data+ " from event "+eventName);

    });



```



- To send acknowledgement back to server



```C#



    socket.On("chat", (eventName, data, ack) =>

    {

        Console.WriteLine("got message "+ data+ " from event "+eventName);

        ack(name, "No error", "Hi there buddy");

    });



```



Implementing Pub-Sub via channels

---------------------------------



#### Creating channel



- For creating and subscribing to channels:



```C#

    var channel=socket.CreateChannel(channelName);

   //var channel=socket.CreateChannel("yolo");



    /**

     * without acknowledgement

     */

     channel.Subscribe();



    /**

     * with acknowledgement

     */



    channel.Subscribe((channelName, error, data) =>

    {

       if (error == null)

       {

             Console.WriteLine("Subscribed to channel "+channelName+" successfully");

       }

    });

```



- For getting list of created channels :



```C#

    List channels = socket.GetChannels();

```



- To get channel by name :



```C#

    var channel=socket.GetChannelByName("yell");

    //Returns null if channel of given name is not present



```



#### Publishing event on channel



- For publishing event :



```C#

       // message can have any data type

    /**

     * without acknowledgement

     */

     channel.Publish(message);



    /**

     * with acknowledgement

     */

       channel.Publish(message, (channelName, error, data) =>

       {

            if (error == null) {

               Console.WriteLine("Published message to channel "+channelName+" successfully");

            }

       });



```



#### Listening to channel



- For listening to channel event :



```C#



    //If instance of channel exists

    channel.OnMessage((channelName, data) =>

    {

         Console.WriteLine("Got message for channel "+channelName+" data is "+data);

    });



    //or

    socket.OnSubscribe(channelName, (channelName, data) =>

    {

        Console.WriteLine("Got message for channel "+channelName+" data is "+data);

    });



```



#### Un-subscribing to channel



```C#



    /**

     * without acknowledgement

     */



     channel.Unsubscribe();



    /**

     * with acknowledgement

     */



    channel.Unsubscribe((name, error, data) =>

    {

        if (error == null) {

            Console.WriteLine("channel unsubscribed successfully");

        }

    });



```



#### Handling SSL connection with server



To enable or disable SSL certficate verification use

```C#



socket.SetSSLCertVerification(true/false);



```



#### Setting HTTP proxy with server



```C#



//args, string : host , int : port

socket.SetProxy(host,port);



```
