构建DateTime对象为SQL数据库插入

我的工作，需要用户输入（除其他事项外），他们增加了系统中的任何服务器的预定的备份时间一个小型Web窗体上。问题是，我挣扎找出拿用户的输入，并建立一个DateTime对象（这是数据库需要）的最佳方式。

I'm working on a small web form that requires the user to input (among other things), the scheduled backup time of whatever server they're adding to the system. The problem is, I'm struggling to find out the best way to take the user input and build a DateTime object (which is what the database requires).

我只真正关心周的日，日（12或24小时制）。时间

I only really care about the Day of Week, Time of Day (12 or 24 hour clock).

我想到了刚刚创建一个空的DateTime对象，然后从用户只需添加我的输入值，但你只能得到，不设置，一周中的一天，一天中的时间等。

I thought about just creating an empty DateTime object and then just adding my input values from the user, but you can only get, not set, the day of week, time of day, etc.

我一直在看日历ASP的控制，这一周选择当天的工作，但我似乎无法找到的一天任何时间的支持。

I've been looking at the Calender asp control, which would work for the day of the week selection, but I can't seem to find any support of time of day.

感谢。
