如何引发跨线程事件

如何从另一个线程引发事件GeocodeAddressEventHandler？

System.Threading.Thread MapThread; WinformMap map ; public delegate void GeocodeAddressEventHandler(object sender, EventArgs e); public event GeocodeAddressEventHandler GeocodeAddressEvent; //How to Raise this Event from another thread?? public void GeocodeAddress_Raised(object sender, EventArgs e) { MapLib.GeocodeAddress("12798 1ST ST", "", "", ""); } public bool LoadMap(string restorepoint) { ////////////////////////Engine Controls//////////////////////////////////////////////////////// try { System.ServiceModel.OperationContext context = System.ServiceModel.OperationContext.Current; //This is to instantiate a winform from a Console (will convert to service shortly) MapThread = new System.Threading.Thread(new System.Threading.ThreadStart(delegate { using (System.ServiceModel.OperationContextScope scope = new System.ServiceModel.OperationContextScope(context)) { this.GeocodeAddressEvent += new GeocodeAddressEventHandler(GeocodeAddress_Raised); } })); MapThread.SetApartmentState(System.Threading.ApartmentState.STA); MapThread.Start(); MapThread.Join(); } catch (Exception ex) { return false; } return true; } 

实际上，事实certificate，在委托的范围终止后，该线程正在终止。 这可能是一种愚蠢的方式，但我在该范围内放置了一段时间Queue.empty {sleep}，因此它永远不会终止，然后我从另一个线程启动了LoadMap，这样它就会阻塞我的WCF服务等待无休止的队列终止。
