推荐答案

如果您的应用程序知道您要在每月的哪一天显示警报，而您的应用程序是每天将要启动和停止的警报，则只需检查一下每月的哪一天到您希望在每次启动应用程序时发出警报的日期.如果其大于或等于您想要的日期，请显示警报.

但是，如果您的程序将启动，然后在数月内没有停止，则您必须编程为其中一个程序更新方法，其中某些代码会检查月份中的某天，并执行与上述相同的操作.另一种方法是使用计时器，但是这些计时器往往会使用很短的毫秒级时间.将一个月设置为毫秒似乎有点荒谬...:P

If your application knows what day of the month you want the alert to show on and your application is one where it will be started and stopped daily then simply check what day of the month it is to what day you wanted the alert every time the application is started. If its greater than or equal to the day you wanted, show the alert.

If however, your program will be started and then not stopped for months you would have to program into say one of you programs update methods some code that checks the day of the month and do the same as above. An alternative method is to use a timer but those tend to be used for short, few millisecond periods of time. Setting one month in milliseconds seems a little ridiculous... :P

以前我无法理解您要询问的内容，但经过深思熟虑，听起来您需要 Windows服务！

Earlier I could not get what you tried to ask but on second thought, it sounds like you are in a need of Windows Service!
