c# - PropertyChangedEventHandler usage question -

i have event, propertychangedeventhandler , raise this:

propertychanged(this, new propertychangedeventargs("logfile")); propertychanged(this, new propertychangedeventargs("nodes")); 

i attached it:

 propertychanged += updatecamxwindowevent;  

how can execute updatecamxwindowevent when event raised "logfile"?

what should change in code?

there no way execute specific method parameters, unless created event. should change updatecamxwindowevent, when parameter logfile.

if can't or logically doesn't make sense in application, can add handler tests argument , if matches, calls method:

propertychanged += (s, e) => { if (e.propertyname == "logfile") updatecamxwindowevent(s,e); }; 

note wouldn't able unsubscribe anonymous method event. if need that, use normal method same functionality.
