推荐答案

你可以设置一个计时器，或者一个监视当前日期和时间的BackgroundWorker几分钟和触发器发送电子邮件 - 这并不困难。但是......效率非常低，因为它会坐在那里一直在等待它每天一次大的机会。



更好解决方案是设置Windows以在特定时间运行您的应用程序：安排一个任务 - Windows帮助 [ ^ ] - 你的应用程序打开，检查它是否今天发送了一个，如果不是这样，那么任何一种方式都会关闭。甚至不需要用户界面！

You could setup a timer, or a BackgroundWorker that monitors the current date and time every couple of minutes and triggers to send the email - that wouldn't be difficult. But...it would be very inefficient as it would be "sitting there" running all the time waiting for it's "one big chance" every day.

A better solution would be to set up Windows to run your app at a specific time: Scheduling a task - Windows Help[^] - your app opens, checks if it's sent one today, if not it does so, then either way closes down. Doesn't even need a user interface!
