struct Complex
{
   public double Re, Im;
   public Complex(double Re, double Im)
   {
      this.Re = Re;
      this.Im = Im;
   }
   public Complex(Complex X)
   {
      Re = B.Re;
      Im = B.Im;
   }
   public static Complex operator + (Complex A, Complex B)
   {
      Complex result = new Complex(A);
      result.Re += B.Re;
      result.Im += B.Im;
   }
}

ListBox.DataSource = yourList;

private void Patient_Load(object sender, EventArgs e)
{
    this.lbNames.DataSource = cn.Patient.Names;
}

Names = new List<theName>();

public class theName
{
    public string use;
    public string prefix;
    public string pqualifier;

     public string Name

//You can use List instead of array.  Couldnt get the < to work so i made it into array
Customer[] customers;

this.lbNames.DataSource = customers;

this.lbNames.DataValueField = "Id";

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private int id;
    public int Id
    {
        get { return id; }
        set { id = value; }
    }

}

protected void Page_Load(object sender, EventArgs e)

    List<Customer> customer = new List<Customer>();
    customer.Add(new Customer("John", 1));
    customer.Add(new Customer("Mike", 2));
