在WPF中设置同步对象

在哪里可以获得ISynchronizeInvoke，以便可以与UI线程同步

System.Timers.Timer gTimer； g定时同步对象

这可能有效

gTimer.SynchronizingObject=新建 DispatcherInformCompataAdapter（this.Dispatcher））

您是混合使用WinForms和WPF，还是新加入WPF？您还有Dispatchermer For clean WPF timer“使用Dispatchermer而不是System.Timers.timer的原因是Dispatchermer与Dispatcher在同一线程上运行”谢谢您，工作得很好。比我预期的代码多得多，谢谢你的解决方案
