C# 格式时间“On The Hour”

Question

I need to format the time from a DateTime object as a string. The catch is, if the time is "on the hour" as in 12:00AM, 8:00PM, I need to trim the zeros and display 12AM or 8PM.

Is there an easy way to do this that I am missing?

Answer 1

您必须自己进行检查：

dateTime.ToString(dateTime.Minute == 0 ? "Htt" : "H:mmtt");

Answer 2

Unless I'm missing something, you can do this:

DateTime date = DateTime.Now;
if (date.Minute == 0) {
   return date.ToString("Htt");
} else {
   return date.ToString("H:mmtt");
}

Obviously with the extra formatting wrapped around this. But that's the core of it.

Answer 3

尝试：

myDateTime.ToString("htt");
