C# DateTime to “YYYYMMDDHHMMSS” format

Question

I want to convert a C# DateTime to \"YYYYMMDDHHMMSS\" format. But I don\'t find a built in method to get this format? Any comments?

Answer 1

Specify formatted DateTime as Utc:

Step 1 - Initial date

var initialDtm = DateTime.Now;

Step 2 - Format date as willing ("yyyyMMddHHmmss")

var formattedDtm = DateTime.ParseExact(initialDtm.ToString("yyyyMMddHHmmss"), "yyyyMMddHHmmss", CultureInfo.InvariantCulture);    

Step 3 - Specify kind of date (Utc)

var specifiedDtm = DateTime.SpecifyKind( formattedDtm, DateTimeKind.Utc);

Answer 3

DateTime.Now.ToString("yyyyMMddHHmmss"); // case sensitive

Answer 4

You can use a custom format string:

DateTime d = DateTime.Now;
string dateString = d.ToString("yyyyMMddHHmmss");

Substitute "hh" for "HH" if you do not want 24-hour clock time.

Answer 5

You've practically written the format yourself.

yourdate.ToString("yyyyMMddHHmmss")

• MM = two digit month
• mm = two digit minutes
• HH = two digit hour, 24 hour clock
• hh = two digit hour, 12 hour clock

Everything else should be self-explanatory.

Answer 6

After spent a lot of hours on Google search, I found the below solution as when I locally give date time, no exception while from other server, there was Error......... Date is not in proper format.. Before saving/ searching Text box date time in C#, just checking either the outer Serer Culture is same like database server culture.. Ex both should be "en-US" or must be both "en-GB" asp below snap shot.

Even with different date format like (dd/mm/yyyy) or (yyyy/mm/dd), it will save or search accurately.
