c# - Websocket-sharp not raising OnOpen event upon opening websocket -

i'm in stages of writing program interface ip camera. bit of code wrote yesterday worked, when came morning didn't. know, did something, best of memory worked when clicked debug before leaving , didn't when clicked debug when came in. left computer on vs running overnight (which never do, , have restarted since) , internet tabs left them. computer locked, unless resourceful individual decided mess me, nothing changed overnight.

i'm using websocket-sharp, , when connect websocket (which seem happen successfully), onopen event isn't raised.

the bit websocket-sharp raises event in following lines.

private void open () {   _inmessage = true;   startreceiving ();   try {     onopen.emit (this, eventargs.empty);   }   catch (exception ex) {     _logger.error (ex.tostring ());     error ("an error has occurred during onopen event.", ex);   } 

it reaches onopen.emit, , doesn't throw exception, seems think it's raising event. event seen below

public event eventhandler onopen; 

it not seem reach line when put breakpoint there isn't paused. i've never used .emit way of raising events before, , not finding in research, maybe somethings going wrong there?

my code below.

public form1()     {         initializecomponent();         this.shown += mainwindow_loaded;     }      void mainwindow_loaded(object sender, eventargs e)     {          using (var ws = new websocket("ws://169.254.101.183"))         {             ws.onmessage += (sender2, e2) =>                 textbox1.text = e2.data.tostring();              ws.connect();             ws.onopen += (sender2,e2) =>                 textbox1.text = "connected";              /*ws.onerror += (sender2, e2) =>                 textbox1.text = e2.message;*/              //textbox1.text = ".";         }     } 

is there obvious reason onopen.emit should not raise onopen event?
