获取日期时间小时和分钟与领先的零 [英] Get Date Time Hours and Minutes with leading Zero

问题描述

我试图找出最简单的代码就从DateTime.Now功能小时和分钟添加前导零。我只需要小时和分钟结合起来，我不需要日期的其余部分。

最新最好的方式做到这一点？

我的代码如下所示：

  DateTime.Now.Hour.ToString（）+ ：+ DateTime.Now.Minute.ToString（）; 
  

不过，我得到这样的16个数据：4 16:04，我需要它看起来像16 ：04。我熟悉日期时间格式的MSDN文章，但我没有看到任何专门解决这个。

是否有可能结合'DateTime.Now.Hour.ToString （）+：+ DateTime.Now.Minute.ToString（）;

如果不是我会拉只有HH：MM出DateTime.Now的容易吗？

寻找代码可能至少行，因为这是我将经常使用的东西。
谢谢

解决方案

  DateTime.Now.ToString（HH：MM ）//非军用时间
 DateTime.Now.ToString（HH：MM）//军事时间（24小时制）
  

使用 HH VS ^ h 将做一个0领先与同毫米几分钟。如果你想秒，可以使用 SS

  MM  - 月与领先0 
 M  - 月，没有前导0 
 DD  - 日与领先的0 
D  - 一天没有前导0 
 YYYY  -  4位数的年份
 YY  -  2位数的年份
 HH  - 军事小时与领先的0 
 H  - 军事小时，没有前导0 
 HH  - 小时与领先的0 
H  - 小时，没有前导0 
毫米 - 与领先的分0 
M  - 分钟无前导0 
 SS  - 第二与领先的0 
S  - 第二，没有前导0 
  

有许多。您应该检查MSDN文档完整的参考：

I'm trying to figure out the simplest code to add leading zeros on to the hours and minutes from the DateTime.Now function. I need to combine only the hours and minutes, and I don't need the rest of the date.

Whats the best way to do this?

My code looks like this:

DateTime.Now.Hour.ToString() + ":" + DateTime.Now.Minute.ToString();

However I get data such as 16:4 for 4:04PM and I need it to look like 16:04. I'm familiar with the msdn articles on datetime formatting but I didn't see anything that addresses this specifically.

Is it possible combining `DateTime.Now.Hour.ToString() + ":" + DateTime.Now.Minute.ToString();

If not how would I pull only the HH:MM out of DateTime.Now easily?

Looking for least lines of code possible because this is something that I will be utilizing often. Thanks

解决方案

DateTime.Now.ToString("hh:mm") // for non military time
DateTime.Now.ToString("HH:mm") // for military time (24 hour clock)

Using hh vs h will do a leading 0. Same with mm for minutes. If you want seconds, you can use ss.

MM - Month with leading 0
M - Month without leading 0
dd - Day with leading 0
d - Day without leading 0
yyyy - 4 Digit year
yy - 2 Digit year
HH - Military Hour with leading 0
H - Military Hour without leading 0
hh - Hour with leading 0
h - Hour without leading 0
mm - Minute with leading 0
m - Minute without leading 0
ss - Second with leading 0
s - Second without leading 0

There are many more. You should check the MSDN documentation for the full reference: https://msdn.microsoft.com/library/zdtaw1bw.aspx
