线程,线程数控制!

多线程与线程池的介绍看这里

            OnTgFinishReport(

        }

            using(TG_EvaluteBaseDatasSet service = (TG_EvaluteBaseDatasSet)Param)

                writeFile(Path,service)    ;
                OnTgReport(
new ReportEvent(service.TE_PASS_RANGE,service.TE_YEAR,service.TE_MONTH,int.Parse(service.TE_I_E_FLAG),int.Parse(service.TE_ENTRY_TYPE),number));
            }

            Interlocked.Decrement(
ref number);
            Console.WriteLine(
"LEFT:"+number);
            
        }

由程序控制线程数量,并且, 由MONITOR进行保护!
