In a .NET 4.5 windows form C# app, how can I bind a datagridview to an object that contains an int array?

Binding

The following runs, but the elements of array[] (in MyObject) don't get displayed in the dataGridView control. Only Checked and Signalname get displayed.
Adding members to MyObject and mapping them to the individual elements of array[] via get and set accessors does the trick, but there's got to be a better way.

    public partial class Form1 : Form
    {
        MyObject[] myArray;
        
        public Form1()
        {
            InitializeComponent();

            myArray = new MyObject[] 
            {
                new MyObject(true, "Signal one"),
                new MyObject(false, "/Signal two"),
                new MyObject(true, "Signal 3"),
                new MyObject(false, "/Signal 4")
            };
        }

        private void button2_Click(object sender, EventArgs e)
        {
            dataGridView1.DataSource = myArray;
        }
    }

    public class MyObject
    {
        public bool Checked { get; set; }
        public string Signalname { get; set; }
        public int[] array;

        public MyObject(bool Ckd, string Signame)
        {
            Checked = Ckd;
            Signalname = Signame;
            array = new int[2] { 111, 222};
        }
    }
}
