HOW TO COPY A FILE USING C#

Hi, in this post I'll explain you an easy way of copy paste a file using the C# language.
The next example will be shown using Microsoft Visual Studio 2008, but this example can be done with whatever ide you prefer.


STEP 1: Create a Console Application. (for quick demonstration purposes)

STEP 2: THE CODE.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace HOWTO_COPY

{

    class Program

    {

        static void Main(string[] args)

        {

            //the try below will manage IOExceptions.

            try

            {

                //creates and fill the bytes array with the data.

                byte[] readBuffer = System.IO.File.ReadAllBytes(@"C:\directory\ORIGINAL-FILE.txt");

                //finally we do the writing of the bytes array back to a new file.

                //(this will overwrite any existing file matching the filename).

                System.IO.File.WriteAllBytes(@"C:\directory\COPIED-FILE.txt", readBuffer);

                Console.WriteLine("FILE SUCCESSFULLY CREATED");

            }

            catch (System.IO.IOException e)

            {

                Console.WriteLine(e.Message);

            }

            //the lines below will freeze the console so you see the output.

            Console.WriteLine("\n\nEND - | C# Quick Examples |");

            Console.ReadLine();

        }

    }

}

SCREENSHOTS

Create the Console Application Project.

Only one file in that directory "C:\directory\"

Running the Application.

File successfully copied, same size, (the data is also the same).

See you in the next example.
