Given a file, and we have to define (set) a new file creation time using C# program.

File.SetCreationTime()

This is a method of "File" class, which is used to define a new file creation time.

Syntax:

void SetCreationTime(path, DateTime);

Parameter(s):

  1. path - Filename with its location.
  2. DateTime - Here we need to pass object of date time class..

Object of DateTime contains following information:

  1. Month
  2. Date
  3. Year
  4. Hour
  5. Minutes
  6. Seconds
  7. AM and PM
  8.

Program

using System;
using System.IO;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main()
		{
			DateTime D1 =  File.GetCreationTime("XYZ.TXT");
			Console.WriteLine("Old File Creation Time : "+D1.ToString());

			DateTime D2 = new DateTime(2017, 12, 25, 19, 45, 10);

			File.SetCreationTime("XYZ.TXT", D2);

			DateTime D3 = File.GetCreationTime("XYZ.TXT");
			Console.WriteLine("New File Creation Time : " + D3.ToString());
		}
	}
}

Output

Old File Creation Time : 10/27/2017 10:45:10 AM
New File Creation Time : 12/25/2017 7:45:10 PM

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