TryParseExact. Suppose we have a format string that we know the date string will adhere to. We can specify the format with letters such as "d" and "y."
Info We import the System.Globalization namespace so that we have access to the CultureInfo type.
Next We specify the date string, and the format string that tells TryParseExact how to parse the string.
Finally We invoke TryParseExact with the required arguments—these can be changed for more precise control of the method.
Dim dateString as String = "Mon 16 Jun 8:30 AM 2008"
Dim format as String = "ddd dd MMM h:mm tt yyyy"
Dim dateTime as DateTime = DateTime.MinValue
' Use TryParseExact to handle the date with a format string.
If DateTime.TryParseExact(dateString, format, CultureInfo.InvariantCulture, DateTimeStyles.None, dateTime)
End Module6/16/2008 8:30:00 AM
Summary. Though parsing strings into DateTimes is not always easy, TryParse and TryParseExact can often be helpful. Usually, TryParse is sufficient for this purpose.
