c# - Adding Event to a Method -


i have http class i've created, , to, if possible, attach method each time either http.post() or http.get() called. i'd able attach event either before, or after.

i see being done in lot of frameworks web, such wordpress , symfony, i'd similar on winforms app.

what design pattern looking achieve can go , google it.

you can create events on objects , invoke them anywhere in code. quite often. 

public event eventhandler getting; public event eventhandler setting;  void get() {     if (getting  != null)         getting.invoke(this, eventargs.empty); }  void post() {     if (setting  != null)         setting.invoke(this, eventargs.empty); }

then other classes can handle these events this:

myhttp.getting += myhttp_getting;  public void myhttp_getting(object sender, eventargs e) {  }

edits:

you invoke event this:

void post() {     if (setting  != null)         setting(this, eventargs.empty); }

you can invoke event within own class. not problem because being able otherwise cause confusing code. check if null, because if there no subscribers null , through nullreferenceexception when invoke it.
