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

To set new file's creation time in C#, we use File.SetCreationTime() method.

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

C# program to set new file creation time

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

Explanation

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