i'm trying list of events of bindingsource , returning null code:

// bs bindingsource propertyinfo propertyinfo = bs.gettype()     .getproperty("events", bindingflags.nonpublic | bindingflags.static |          bindingflags.instance | bindingflags.flattenhierarchy);  eventhandlerlist eventhandlerlist = propertyinfo     .getvalue(bs, new object[] { }) eventhandlerlist;  // following line returns null fieldinfo fieldinfo = typeof(bindingsource)     .getfield("addingnew", bindingflags.instance | bindingflags.flattenhierarchy |          bindingflags.instance | bindingflags.public | bindingflags.nonpublic);  

i put possible bindingflags error persists. doing wrong?

found better answer duplicate addeventhandler using reflection - use type.getevent.

---

addingnew event, manipulate need corresponding auto-generated methods - "remove_{eventname}" , "add_{eventname}":

var add = typeof(system.windows.forms.bindingsource).getmethod("add_addingnew"); 

proper way use getevent:

var adding = typeof(system.windows.forms.bindingsource).getevent("addingnew"); 

see how events implemented details on how events implemented.
