如何在C#中创建警报 [英] How to create alert in c#

问题描述

推荐答案

最好告诉您有关应用程序上下文的更多信息.

It will be better if you tell more details about the context of your application.

第二个用户"何时出现该怎么办?将他的数据提交给数据库进行保存或更新，然后用一条消息提醒他，例如原始数据已更改，您要覆盖还是获取?".这可以通过保持 原始行的原始数据/日期修改值，以及在您提交新数据"之前与数据库进行比较和验证.

What about when the "2nd user" submits his data to the DB for save or update, then you alert him with a message for example "The original data has changed, would you like to override or retreive?". That can be achieved by keeping the original data/ date modified value for the original row and before you submit the "new data" to the DB you do a compare and validate.
