How to get the average size of all files in a directory using LINQ with WinForms and C#

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 average_files_size = (int)files.Average();

            MessageBox.Show(files.Average().ToString() + " bytes");
            
            MessageBox.Show(average_files_size.ToString() + " bytes");
        }
    }
}
