推荐答案

没有计时器就无法眨眼，不.文本框中没有内置的闪烁功能.

You can''t make things blink without a timer, no. There''s no blink functionality built in to the textbox.

不确定为什么不想使用计时器，但是如果愿意，可以始终运行另一个线程来运行将跟踪经过的时间并切换文本框的属性.为此，您可以使用例如 BackgroundWorker [

Not sure why you don''t want to use the timer but if you like, you can always have another thread running which would track the elapsed time and toggle the properties of a textbox. For this purpose you can use for example a BackgroundWorker[^].

Just remember that depending on the technology you may not update the properties of a UI control from another thread so you need to check if invoke is required (or similar, again depending on the UI technology).
