C# ComboBox

Today I had some troubles finding out how to implement a simple ComboBox in my C# Windows Forms program. Here's my solution because maybe somebody else can use it.

1) Add a ComboBox to the project (drag and drop from the Toolbox)
2) Add two labels to the project (label1.Visible = false, label2.Visible = true)

Add the code to Form1.cs:

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            comboBox1.Items.Add("Europe");
            comboBox1.Items.Add("America");
            comboBox1.Items.Add("Russia");
        }

        public void combo_selected(object Sender, EventArgs e)
        {
            label1.Text = comboBox1.Text;
        }

        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            comboBox1.SelectedIndexChanged += new EventHandler(this.combo_selected);
            comboBox1.SelectedIndexChanged -= comboBox1_SelectedIndexChanged;
            comboBox1.SelectedItem.ToString();
            label1.Text = comboBox1.Text;
        }

        // Now check if everything has worked !

        private void button1_Click(object sender, EventArgs e)
        {
            label2.Text = label1.Text;
        }
    }
}

Now, debug, make a selection in the combox and press the button. If everything went well, label2 will show the item you have chosen in the combobox.
