Question

我需要在工作线程完成时通知主线程。当我接受一个委托并在另一个线程完成时执行它，它就会在该线程上执行，这不是我想要的。由于我的一些限制（＆＃39;更新＆＃39;在Unity Editor中没有调用每一帧），我都无法检查它是否已完成。我有其他选择吗？

//This is a helper coroutine
IEnumerable RunOffMainThread(Action toRun, Action callback) {
  bool done = false;
  new Thread(()=>{
    toRun();
    done = true;
  }).Start();
  while (!done)
    yield return null;
  callback();
}

//This is the method you call to start it
void DoSomethingOffMainThread() {
  StartCoroutine(RunOffMainThread(ToRun, OnFinished));
}

//This is the method that does the work
void ToRun() {
  //Do something slow here
}

//This is the method that's called when finished
void OnFinished() {
   //off main thread code finished, back on main thread now
}
