c# - adding listBox data using list<Object>

Hope this helps.

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            //Create a listbox, with given height/width and top/left
            var lstBox = new ListBox
            {
                Width = 300,
                Height = 300,
                Top = 10,
                Left = 10
            };

            //Add the listbox to your form
            this.Controls.Add(lstBox);

            //Create a list of your customclass
            var listCustomClass = new List<CustomClass>();

            //Populate the list with values
            for (int i = 0; i < 50; i++)
            {
                //create an instanze of your customclass
                var customClass = new CustomClass();
