如何在VB.net中将日期转换为格式化字符串？

Question

There seems to be a million questions here on converting a string to a Date, but not vice-versa. When I convert a Date object to a string using mydate.toString I get a string in the format 16/01/2013 13:00:00 .

But what I really want is 2013-01-16 13:00:00 . I can't see any functions on the Date object that do this for me, do I need to use a regex or something instead?

Answer 1

You can use the ToString overload. Have a look at this page for more info

So just Use myDate.ToString("yyyy-MM-dd HH:mm:ss")

or something equivalent

Answer 2

你可以使用格式函数来做，这是一个示例：

Format(mydate, "yyyy-MM-dd HH:mm:ss")

Answer 3

myDate.ToString("yyyy-MM-dd HH:mm:ss")

大都会HH是您指定的24小时格式

Answer 4

I like:

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
myDate.ToString(timeFormat)

Easy to maintain if you need to use it in several parts of your code, date formats always seem to change sooner or later.

Answer 5

Dim timeFormat As String = "yyyy-MM-dd HH:mm:ss"
objBL.date = Convert.ToDateTime(txtDate.Value).ToString(timeFormat)
