How to Reliably Convert a String to a DateTime Object in C#?

Converting a String to a DateTime in C#

In C#, formatting a DateTime object using ToString("yyyyMMddHHmmss", CultureInfo.InvariantCulture) results in a string representation of the date and time. However, converting this string back into a DateTime object can be tricky.

One common approach, Convert.ToDateTime(...), may fail due to a format mismatch. To address this, consider using DateTime.ParseExact:

DateTime dateTime = DateTime.ParseExact(str, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

This method parses the string based on the specified format and returns a DateTime object.

Alternatively, for non-exact matches, employ DateTime.TryParseExact:

DateTime dateTime;
DateTime.TryParseExact(str, "yyyyMMddHHmmss",
    CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime);

This method returns true if the conversion succeeds, and false otherwise. The output dateTime variable will contain the parsed DateTime object if successful.
