Convert String format with full date to Date format


How can I convert “18 mai 2020 16:15:44” as String to Date ?

Thanks :slight_smile:


with the assumption that the lower case written mai comes from a french local have a look here:

DateTime.ParseExact("18 mai 2020 16:15:44","dd MMM yyyy HH:mm:ss",CultureInfo.CreateSpecificCulture("fr-FR"))

feel free to change to another culture if needed
ensure following:



Thank you for your help, it works fine. But please can you show me how to display it on this format please ?


Thank you in advance !

give a try on following:
DateTime.ParseExact(“18 mai 2020 16:15:44”,“dd MMM yyyy HH:mm:ss”,CultureInfo.CreateSpecificCulture(“fr-FR”)).toString(“dd/MM/yyyy”)

Hi, it worked fine, until i found an other issue, sometimes dates are as this format “3 juin 2020 09:49:50”, do you have any idea how can manage this type too please ?

Thank you

Hello @ppr

I found this solution, but can’t figure out how you use it ?

myString = DateTime.ParseExact(myString, arrFormat,CultureInfo.CreateSpecificCulture(“fr-FR”)).toString(“dd/MM/yyyy”)

Can you explain please ?

lets assume the processed data comes formated within different formats like 01 juin 2020 or 01.06.2020 then we can handle this for parsing the date

just use the code from above and ensure that the used string array “arrFormat” contains the different format patterns. Does mean:

have a variable in scope: arrFormat, DataType: String(),
for the example: 01 juin 2020 or 01.06.2020 the content of the array would be:
{dd MMMM yyyy, dd.MM.yyyy}

It’s what i did, but i have an error…

you missed out the 4th parameter:
DateTime.ParseExact(YourDateString, arrFormats, YourCultureInfo, DateTimeStyles.None)

I don’t get what you want me to do, can you please correct me this ?

Change your code to following:
DateTime.ParseExact(varString, arrArray, CultureInfo.CreateSpecificCulture(“fr-FR”), DateTimeStyles.None )

the ParseExact Method requires these 4 arguments in case you want to work with string array expressing the different date formats

I unterstand now, thank you for your help and kindess !

In case others have the same issue, here’s an example :

DateTime.ParseExact(varString, varArray, CultureInfo.CreateSpecificCulture(“fr-FR”), DateTimeStyles.None).toString(“dd/MM/yyyy”)



Based on your examples,
18 mai 2020 16:15:44
3 juin 2020 09:49:50
I believe you need only one date format.
d MMM yyyy HH:mm:ss

It is almost the same as ppr suggested with the only difference that uses d instead of dd

  • d -> Represents the day of the month as a number from 1 through 31.
  • dd -> Represents the day of the month as a number from 01 through 31.

If the requirements are different, you can also use an array of date formats as you have already :slight_smile:
