        public Form1()
        {
            InitializeComponent();
        }

            listBox1.Items.Add("Raj");
            listBox1.Items.Add("Raju");

            listBox1.Items.Add("Ian");

        }

       

      
        private void btn_right_Click(object sender, EventArgs e)
        {
            if (listBox2.Items.Contains(listBox1.SelectedItem) == true)
            {
                MessageBox.Show("Item Exits");
            }
            else
            {
                listBox2.Items.Add(listBox1.SelectedItem);
                int i = 0;
                i = listBox1.SelectedIndex;
                listBox1.Items.RemoveAt(i);

            }
        }

        private void btnleft_Click(object sender, EventArgs e)
        {
            listBox1.Items.Add(listBox2.SelectedItem);
            int i = 0;
            i = listBox2.SelectedIndex;
            listBox2.Items.RemoveAt(i);
        }
    }
}
