I'm trying to implement Websockets in c# and i tried many ways but nothing works fine.

ii) tried with WebSocketSharp.WebSocket class but closing immediately after opening connection

iii) WebSocket4Net.WebSocket same problem closing connection immediately

can anyone please help me in solving this issue.A big thanks in advance.

class SocketConnection
{
    public static WebSocketSharp.WebSocket client;

    public void connectionEstablish()
    {
        //---------------------------WebSocketSharp ----------------------------

        using (client = new WebSocketSharp.WebSocket("ws://localhost:8182"))
        {
            client.OnClose += new EventHandler<CloseEventArgs>(onClosed);
            client.OnMessage += new EventHandler<MessageEventArgs>(onReceived);
            client.OnOpen += new EventHandler(OnConnectionOpen);

            client.Connect();

        }
      }
    public static void onClosed(object sender, EventArgs e)
    {
      Console.WriteLine("Inclose");
    }
    public static void onReceived(object sender, MessageEventArgs e)
    {
      Console.WriteLine("received");
    }
    public void OnConnectionOpen(object sender, EventArgs e)
    {
      Console.WriteLine("opened connection");
    }
}

I hope that your issue is with the using in the code. The variable client is an using variable so It will get disposed when using block ends(That is what the purpose of using, calling dispose automatically).

That means after executing the client.Connect(); using block ends and hence the object get disposed. To verify this, try remove the using block and change the code like the following:

var client = new WebSocketSharp.WebSocket("ws://localhost:8182");

Don't forget to dispose the object after use.
