推荐答案
1)您的应用程序必须连续运行才能正常工作，即您必须具有Windows服务等.
2)将日期保存到文件或数据库中.
3)创建一个Thread，它每1秒钟休眠一次，并检查日期是否已过，如果是，请执行emailsend方法.
1) Your application must be running continuously for this to work ie you must have a windows service etc.
2) Save your dates to a file or a database.
3) Create aThreadwhich sleeps every 1 sec and checks if the dates have been passed, if so execute theemailsendmethod.

在计时器滴答事件中，检查所需的日期和时间，
如果其(检查值)值为true
然后调用电子邮件发送方法.
In the timer tick event, check the required date and time ,
If its(checking value) value is true
then call the Email send method..
