Given a file and a directory and we have to find their last write time in UTC using C# program.

File.GetLastWriteTimeUtc()

This is a method of "File class, it is used to get the last write time in UTC format of given file/directory.

Syntax:

File.GetLastWriteTimeUtc(path);

Parameter(s):

  1. path - Location of file or directory.

Last write time contains following detail:

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

Program

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            DateTime dt1;
            DateTime dt2;

            dt1 = File.GetLastWriteTimeUtc("ABC.TXT");
            Console.WriteLine("Last Write Time in UTC of file(ABC.TXT) : " + dt1);

            dt2 = File.GetLastWriteTimeUtc("mydir");
            Console.WriteLine("Last Write Time in UTC of directory(mydir) : " + dt2);
        }
    }
}

Output

Last Write Time in UTC of file(ABC.TXT) : 10/31/2017 9:38:13 PM
Last Write Time in UTC of directory(mydir) : 10/31/2017 9:08:23 PM

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