N.B: Beginners please follow the link to know How to create your First Windows Form Application.


Steps

3. Now click on the Form and get the event handler for Form Load and update the code 
    with the one shown below.

using System.Windows.Forms;

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

        private void Form1_Load(object sender, EventArgs e)
        {
            getIP();
        }
        void getIP()
        {
            string localIP = string.Empty;
            IPHostEntry host;

            host = Dns.GetHostEntry(Dns.GetHostName());
            foreach (IPAddress ip in host.AddressList)
            {
                if (ip.AddressFamily.ToString() == "InterNetwork")
                {
                    localIP = ip.ToString();
                }
            }
            textBox1.Text = localIP;

        }
    }

}
