c# - How to make EndInvoke generic? -

-

in code raise events using begininvoke, because each event has different eventargs, code full of duplicate functions, like:

private void endasyncconnect(iasyncresult iar) {     var ar = (system.runtime.remoting.messaging.asyncresult)iar;     var invokedmethod = (eventhandler<infoargs>)ar.asyncdelegate;      invokedmethod.endinvoke(iar); }  private void endasyncreceived(iasyncresult iar) {     var ar = (system.runtime.remoting.messaging.asyncresult)iar;     var invokedmethod = (eventhandler<receivedargs>)ar.asyncdelegate;      invokedmethod.endinvoke(iar); }

is there way make endasync function generic events?

if event delegate types eventhandler<t>, should work:

void completioncallback<t>(iasyncresult iar)     t : eventargs {     var ar = (system.runtime.remoting.messaging.asyncresult)iar;     var invokedmethod = (eventhandler<t>)ar.asyncdelegate;     invokedmethod.endinvoke(iar); }

Delphi interface implements -

i expect reference counting should work on outer aggregating object in interface implementation. if can refer example: clarity in classes implementing multiple interfaces (alternative delegation): here minimal reproduction of behaviour: program so16210993; {$apptype console} type ifoo = interface procedure foo; end; tfooimpl = class(tinterfacedobject, ifoo) procedure foo; end; tcontainer = class(tinterfacedobject, ifoo) private ffoo: ifoo; public constructor create; destructor destroy; override; property foo: ifoo read ffoo implements ifoo; end; procedure tfooimpl.foo; begin writeln('tfooimpl.foo called'); end; constructor tcontainer.create; begin inherited; ffoo := tfooimpl.create; end; destructor tcontainer.destroy; begin writeln('tcontainer.destroy called');//this line never runs inherited; end; procedure main; var foo : ifoo; begin foo := tcontainer.create; foo.foo; end; begin main; readln...
