See more:

My requirement was to write a code that can accept two type of date format i.e yyyymmddhhmmss and yyyymmdd. I have written the code but it is working for few date but not for all.

C#

string[] formats = { "yyyymmdd","yyyymmddhhmmss" };
            bool valid = true;

C#

if (!DateTime.TryParseExact(DesiredReportVersionDate, formats, new CultureInfo("en-US"), DateTimeStyles.None, out timevalue))
            {

                valid = false;
                throw new Exception("invalid format" + timevalue);
            }

However,passing 19901212033047 value is giving exception.It should be valid as per my understanding.

Please help.

Thanks in advance

Change the format strings from

C#

string[] formats = { "yyyymmdd","yyyymmddhhmmss" };
            bool valid = true;

to

C#

string[] formats = { "yyyyMMdd","yyyyMMddhhmmss" };
            bool valid = true;

MM = month
mm = minutes.

use HH instead of hh if you want 24 hour time.

Solution 1

The problem should be that you using m (small m) for month and minute also.
It should be M (capital M) for month and m (small m) for minute...

C#

string[] formats = { "yyyyMMdd","yyyyMMddhhmmss" };
