Trying to add some code into existing project

Question

Hi,

I'm fighting to understand how to add code found on the internet correctly into a new project.

Let me give u an example here. If i Add some code i found on the internet it gives a lot of errors. The fist error is : The type or namespace name 'Process' could not be found (are you missing a using directive or an assembly reference?)

Am I inserting the code in the wrong place. Please advice.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {

// THIS IS CODE FOUND ON THE INTERNET THAT I WANT TO TEST //
// START//

            // there are always multiple chrome processes, so we have to loop through all of them to find the
            // process with a Window Handle and an automation element of name "Address and search bar"
            Process[] procsChrome = Process.GetProcessesByName("chrome");
            foreach (Process chrome in procsChrome)
            {
                // the chrome process must have a window
                if (chrome.MainWindowHandle == IntPtr.Zero)
                {
                    continue;
                }

                // find the automation element
                AutomationElement elm = AutomationElement.FromHandle(chrome.MainWindowHandle);
