Answer 1

namespace WinFormsApp1
{
    public partial class Form1 : Form
    {
    public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string[] dir = Directory.GetFiles("d:\\Test");

            var files = dir.Select(file => new FileInfo(file).Length);

            int max_file_size = 0;
            foreach (int element in files)
            {
                max_file_size = Math.Max(max_file_size, element);
            }
            
            MessageBox.Show(max_file_size.ToString() + " bytes");
        }
    }
}
