c# - Asynchronous calling a method -

here old code phone call asyn function:

public class caller { public void calculate(calcparameters calcparameters, string sourceapp) { asynccaller caller = new asynccaller(_username, _password, new token()); caller.calculated += new calculatedhandler(oncalculated); caller.calculate(sourceapp, calcparameters); } protected virtual void oncalculated(object sender, calculatedeventargs e) { if (oncalculatedevent != null) oncalculatedevent(e); } public void calculate(string calcid, webservice.calcparameters calcparams) { calculate(0, calcid, calcparams); } public void calculate(long callid, string calcid, webservice.calcparameters calcparams) { seek { lock(this) { worker wsworker = makecalculateworker(callid, calcid, new oncalculatedhandler(oncalculated), calcparams); thread wsthread = new thread(new threadstart(wsworker.calculate)); wsthread.isbackground = true; wsthread.start(); } } grab (exception ex) { _log.writeerror( assembly.getexecutingassembly().getname().name, this.gettype().name, methodbase.getcurrentmethod().name, _username, ex.message); throw ex; } } }

but need using delegate , begininvoke..

please can help me or give me samples read from.

thanks

here msdn illustration explains how utilize asynchronous delegates.

read through go through step step if programme understand it.
