Below are the programs to illustrate the File.SetCreationTime(String, DateTime) method.Program 1: Before running the below code, a file file.txt is created with some contents shown below- 
 
C#
// C# program to illustrate the usage// of File.SetCreationTime(String, DateTime) method  // Using System and System.IO namespacesusing System;using System.IO;  class GFG {    static void Main()    {        // Specifying a new date and time        DateTime D1 = new DateTime(2017, 12, 25, 2, 6, 8);          // Calling SetCreationTime() function        // to set the new date and time        File.SetCreationTime("file.txt", D1);          // Calling the GetCreationTime() function        // to get the creation date and time        DateTime D2 = File.GetCreationTime("file.txt");        Console.WriteLine("The File Creation Time is : " + D2.ToString());    }}
Output:  
The File Creation Time is : 25/12/2017 02:06:08 AM
Program 2: Before running the below code, a file file.txt is created with some contents shown below: 
 
C#
// C# program to illustrate the usage// of File.SetCreationTime(String, DateTime) method  // Using System and System.IO namespacesusing System;using System.IO;  class GFG {    static void Main()    {        // Calling the GetCreationTime() function to        // get the original file creation date and time        DateTime D1 = File.GetCreationTime("file.txt");        Console.WriteLine("File Creation Old Time is: " + D1.ToString());          // Specifying a new date and time        DateTime D2 = new DateTime(2017, 12, 25, 2, 6, 8);          // Calling SetCreationTime() function        // to set the new date and time        File.SetCreationTime("file.txt", D2);          // Calling the GetCreationTime() function        // to get the new creation date and time        DateTime D3 = File.GetCreationTime("file.txt");        Console.WriteLine("File Creation new Time is : " + D3.ToString());    }}
Output:  
File Creation Old Time is: 4/25/2020 11:26:14 AM
