Given a file and we have to copy its content to another file using C# program.

File.Copy()

This is a method of "File class, which is used to copy all data of source file to the destination file.

Syntax:

File.Copy(source_file,dest_file);

Parameter(s):

  1. source_file - From which we are copying data content.
  2. dest_file - In which data is being copied.

Program

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            string data;

            data = File.ReadAllText("ABC.TXT");
            Console.WriteLine("Content of ABC.TXT :\n"+data);

            File.Copy("ABC.TXT", "XYZ.TXT");

            data = File.ReadAllText("XYZ.TXT");
            Console.WriteLine("Content of XYZ.TXT :\n" + data);

        }
    }
}

Output

Content of ABC.TXT :
India is a great country.
Content of XYZ.TXT :
India is a great country.

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

In above function, overwriting a file with the same name is not allowed.
