Given a file and we have to define its last access time in UTC format using C# program.

File.SetLastAccessTimeUtc()

This is a method of "File class, which defines the last access time in UTC format of a file or directory.

Syntax:

File.SetLastAccessTimeUtc(path);

Parameter(s):

  1. path - Location of file or directory.

We can set following detail of last access time:

  • Date
  • Month
  • Year
  • Hour
  • Minute
  • Second
  • AM/PM

Program

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            DateTime dt1;

            Console.WriteLine("Time before set last access time in UTC:");

            dt1 = File.GetLastAccessTimeUtc("ABC.TXT");
            Console.WriteLine("\tLast Access Time of file(ABC.TXT) in UTC: " + dt1);


            File.SetLastAccessTimeUtc("ABC.TXT", DateTime.Now);

            Console.WriteLine("Time After set last access time in UTC");

            dt1 = File.GetLastAccessTimeUtc("ABC.TXT");
            Console.WriteLine("\tLast Access Time of file(ABC.TXT) in UTC: " + dt1);


        }
    }
}

Output

Time before set last access time in UTC:
        Last Access Time of file(ABC.TXT) in UTC: 10/31/2017 4:25:36 PM
Time After set last access time in UTC
        Last Access Time of file(ABC.TXT) in UTC: 10/31/2017 4:37:29 PM

Note: In above program, we need to remember, when we use "File" class, System.IO namespace must be included in the program.
