推荐答案

，您尝试找到所有答案的原因是什么?

您是否完全上过DateTime类?此处:
MSDN:DateTime [ MSDN:TimeSpan [ MSDN:DateTimePicker类 [

And what have you tried to find answers to all of them?

Did you went through the DateTime class at all? Here:
MSDN: DateTime[^]
MSDN: TimeSpan[^]
MSDN: DateTimePicker Class[^]

Go through them, try out and then if you have any doubt/issue, ask specific question.

要在MS SQL Server中计算两个日期之间的日期差，请使用 GETDATE() [ CAST和CONVERT [

To calculate date differences between 2 dates in MS SQL Server, use DATEDIFF()[^] function.
To get current date on MS SQL Server use GETDATE()[^] function.
To "format" the date and time, use CAST and CONVERT[^] functions.
