What format do I use for Date/Time when writing to an XML file using .NET? Do I simply use DateTime.ToString(), or do I have to use a specific format?

Can use the following conversion code to convert UTC format string to any other DateTime format. string result = Convert. ToDateTime("2011-02-04T00:00:00+05:30"). ToString("MM/dd/yyyy h:mm:ss tt");
The international standard recommends writing the date as year, then month, then the day: YYYY-MM-DD. So if both Australians and Americans used this, they would both write the date as 2019-02-03. Writing the date this way avoids confusion by placing the year first.
Lexical form The lexical form of xs:dateTime is a finite-length sequence of characters of the following form: yyyy - mm - dd T hh : mm : ss . ssssssssssss zzzzzz . The following abbreviations describe this form: yyyy. A four-digit numeral that represents the year.
I always use the ISO 8601 format (e.g. 2008-10-31T15:07:38.6875000-05:00) -- date.ToString("o"). It is the XSD date format as well. That is the preferred format and a Standard Date and Time Format string, although you can use a manual format string if necessary if you don't want the 'T' between the date and time: date.ToString("yyyy-MM-dd HH:mm:ss");
EDIT: If you are using a generated class from an XSD or Web Service, you can just assign the DateTime instance directly to the class property. If you are writing XML text, then use the above.
