I have this date format yy/MM/dd HH:mm:ss ex: 12/02/21 10:56:09. The problem is, when i try to convert it to different format using this code:
yy/MM/dd HH:mm:ss
12/02/21 10:56:09
Assuming that you are meaning to ask how to get VB to parse the date as yy/MM/dd, the answer is simple: just use DateTime.ParseExact("12/02/12 10:56:09", "yy/MM/dd HH:mm:ss") and then use ToString() as before.
DateTime.ParseExact("12/02/12 10:56:09", "yy/MM/dd HH:mm:ss")
ToString()
