c# - How to stop co-routine?

Question

When two co-routines are running, how do you stop the first co-routine?

GLOBALS.stableTime = 5;

IEnumerator StableWaittingTime ()
{
        yield return new WaitForSeconds (1f);
        if (GLOBALS.stableTime == 0) {
                GameManager.instance.LevelFaildMethod ();
        } else {
                GameManager.instance.stableWaittingTime.text = GLOBALS.stableTime.ToString ();
                GLOBALS.stableTime--;
                StartCoroutine ("StableWaittingTime");
        }
}

There are three ways to stop coroutines.

1. The first is to call StopAllCoroutines(), which will obviously stop all running coroutines.
2. The second is to call StopCoroutine(coroutine), where coroutine is a variable name given to your IEnumerator.
3. And the third is to do a yield break from within the coroutine.

Worth noting is that both StopAllCoroutines and StopCoroutine can only stop a coroutine when the coroutine reaches a yield return *.

So if you have two coroutines with the same name and you want to stop the one you are executing in you do yield break. Interestingly, if you want to stop every other coroutine besides the one you are executing in, you call StopCoroutines() from within that coroutine.
