The below examples show how to format DateTime using String.Format method, Standard formats can be used to convert DateTime into the string format.
DateTime dt = DateTime.Now;
string.Format("{0:MM/dd/yyyy}", dt) // 06/12/2020
string.Format("{0:dd-MM-yyyy}", dt) // 12/06/2020
string.Format("{0:MMM dd, yyyy}", dt) // Jun 12, 2020
string.Format("{0:dddd, dd MMMM yyyy H:mm}", dt) // Friday, 12 June 2020 16:06
string.Format("{0:dddd, dd MMMM yyyy h:mm tt}", dt) // Friday, 12 June 2020 4:06 PM
string.Format("{0:dddd, dd MMMM yyyy HH:mm}", dt) // Friday, 12 June 2020 16:06
string.Format("{0:dddd, dd MMMM yyyy hh:mm tt}", dt) // Friday, 12 June 2020 04:06 PM
string.Format("{0:dddd, dd MMMM yyyy HH:mm:ss}", dt) // Friday, 12 June 2020 16:06:55
string.Format("{0:MM/dd/yyyy HH:mm}", dt) // 06/12/2020 16:06
string.Format("{0:MM/dd/yyyy hh:mm tt}", dt) // 06/12/2020 04:06 PM
string.Format("{0:MM/dd/yyyy H:mm}", dt) // 06/12/2020 16:06
string.Format("{0:MM/dd/yyyy h:mm tt}", dt) // 06/12/2020 4:06 PM
string.Format("{0:MM/dd/yyyy HH:mm:ss}", dt) // 06/12/2020 16:06:55
string.Format("{0:MMMM dd}", dt) // June 12
string.Format("{0:HH:mm}", dt) // 16:06
string.Format("{0:hh:mm tt}", dt) // 04:06 PM
string.Format("{0:H:mm}", dt) // 16:06
string.Format("{0:h:mm tt}", dt) // 4:06 PM
string.Format("{0:HH:mm:ss}", dt) // 16:06:55
string.Format("{0:yyyy MMMM}", dt) // 2020 June
string.Format("{0:yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss.fffffffK}", dt) // 2020'-'06'-'12'T'16':'06':'55.7673403+10:00
string.Format("{0:ddd, dd MMM yyy HH’:’mm’:’ss ‘GMT’}", dt) // Fri, 12 Jun 2020 16':'06':'55 'G6T'
string.Format("{0:yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss}", dt) // 2020'-'06'-'12'T'16':'06':'55
The DateTime string format can be also done using DateTime.ToString() method. For example,
DateTime.Now.ToString("MM/dd/yyyy") // 06/12/2020
DateTime.Now.ToString("dd-MM-yyyy") // 12/06/2020
DateTime.Now.ToString("MMM dd, yyyy") // Jun 12, 2020
DateTime.Now.ToString("dddd, dd MMMM yyyy H:mm") // Friday, 12 June 2020 16:06
DateTime.Now.ToString("MMMM dd") // June 12
DateTime.Now.ToString("HH:mm") // 16:06
DateTime.Now.ToString("hh:mm tt") // 04:06 PM
