ExternalDataExchangeService服务需要在wf引擎启动前加载
WorkflowRuntime engien = new WorkflowRuntime ();

1. ExternalDataExchangeService edes = new ExternalDataExchangeService();
2. engien.addService(edes);
3. ExternalService es = new ExternalService();//自定义的LoclaService
4. edes.addService(es);
5. engien.startRuntime();

获取ExternalService ,调用其中的方法触发事件

public event EventHandler<ExternalDataEventArgs> 事件;

ExternalService中的raisEvent方法来触发事件
        public void RaiseEvent(Guid instanceId)
        {
            ExternalDataEventArgs ede = new ExternalDataEventArgs(instanceId);
            事件(null, ede);
        }


ExternalService es = (ExternalService )engien.gerService<ExternalDataExchangeService >().getService(typeof(ExternalService ));
es.RaiseEvent(instanceId);
