(REL) Auto Refreshing ListBox C#

So I know most people know how to do this but this is for all the people that still use refresh buttons

using System.Threading; //For Auto Refresh
using System.Threading.Tasks; //I forget if you need this just adding it because I can
using System.IO; //For File.ReadAllText

//Code for the auto fresh to work
        public executor()
        {
            InitializeComponent();
            new DirectoryInfo("./Scripts").GetFileSystemInfos().ToList().ForEach(
            info => listBox1.Items.Add(info.Name));

            var fileSystemWatcher = new FileSystemWatcher("./Scripts")
            { EnableRaisingEvents = true };

            var context = SynchronizationContext.Current;
            fileSystemWatcher.Created += (s, e) => {
            context.Post(val => listBox1.Items.Add(e.Name), s);
            };
        }


//Allow the listbox put code into the TextBox
        private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            TextBox.Text = File.ReadAllText($"./Scripts/{listBox1.SelectedItem}");
        }
