c# - DateTime.Now 在 winforms 中的问题

Question

var insertDate = DateTime.Now

我打开了 Windows 应用程序，25/07/2013但在29/07/2013.

在数据库中，25/07/2013存储而不是29/07/2013.

请建议我为什么？

提前致谢。

Answer 1

是的。您需要在将值写入数据库之前设置您的 insertDate。

insertDate = DateTime.Now;
// write to database

Answer 2

The line of code

var insertDate = DateTime.Now;

doesn't "bind" that value to "the current time" so that it is "always up-to-date" but it sets the value of that variable insertDate to the date/time at the instant of execution.

So like Derek already said, set this variable just before you perform the insert.
