## Overview
**`File.Copy()`** is a file class method that copies the contents of a file to a file that is created by this function.

## Syntax
```C#
File.Copy(string source, string destination)
```
## Parameters
* **`source`**: This is the name of the file whose contents we want to copy.

* **`destination`**: This is the file that will be created by the `File.Copy()` method and filled with the contents of the file with the name `source`.

## Example
Let's look at the code below:


// Using System, System.IO,
// System.Text and System.Linq namespaces
using System;
using System.IO;
using System.Text;
using System.Linq;

class HelloWorld
{
    static void Main()
    {
        // get file names
        string file1 = @"test1.txt";
        string file2 = @"test2.txt";

        // copy file 1 to file 2
        File.Copy(file1, file2);

        // if copy was successful
        Console.WriteLine("File copy successful!!!");

        // check file contents
        Console.WriteLine("file 1: {0}",File.ReadAllText(file1));
        Console.WriteLine("file 2: {0}",File.ReadAllText(file2));
    }
}

## Explanation
First, we create a file called `test1.txt` and write `"Welcome to Edpresso!"` inside it.
* **Lines 13 and 14**: We get the file names.
* **Line 17**: We copy `file1` to `file2`. 
* **Line 19**: We print a success message if file copying is successful.
* **Lines 23 and 24**: We print out the file contents to ensure success.
