C#: Long integer to valid time

Last update on December 20 2024 12:39:52 (UTC/GMT +8 hours)

Write a C# Sharp program which shows that when a time that falls within this range is converted to a long integer value and restored and the original value is adjusted to become a valid time.

Sample Solution:-

C# Sharp Code:

using System;

public class Example22
{
   public static void Main()
   {
      // Create a DateTime object with a potentially invalid time (Daylight Saving Time transition)
      DateTime date1 = new DateTime(2016, 3, 14, 2, 30, 00);

      // Check if the provided time is an invalid time within the local time zone
      Console.WriteLine("Invalid Time: {0}", TimeZoneInfo.Local.IsInvalidTime(date1));

      // Convert the DateTime object to a file time format (number of 100-nanosecond intervals since January 1, 1601 UTC)
      long ft = date1.ToFileTime();

      // Convert the file time back to a DateTime object
      DateTime date2 = DateTime.FromFileTime(ft);

      // Display the original and reconstructed DateTime objects
      Console.WriteLine("{0} -> {1}", date1, date2); 
   }
}

Sample Output:

Invalid Time: False                                                                                           
3/14/2016 2:30:00 AM -> 3/14/2016 2:30:00 AM
