Fun C# ASP.NET Page for Lotto Numbers

To lighten the mood in my office, I came up with fun C# ASP.NET page to randomly display lotto numbers. It's configured for the Cali lotto format but you can easily modify it for whatever state your in. Enjoy.

using System;
using System.Web;
using System.Text;

public partial class numbers : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)


protected void GetLottoNumbers(object sender, EventArgs e)
ArrayList arlNum = new ArrayList();
Random RandomClass = new Random();

while (arlNum.Count < 5)
int g = RandomClass.Next(1, 56);
if (!arlNum.Contains(g))


pnlNum.Visible = true;
lblN1.Text = arlNum[0].ToString();
lblN2.Text = arlNum[1].ToString();
lblN3.Text = arlNum[2].ToString();
lblN4.Text = arlNum[3].ToString();
lblN5.Text = arlNum[4].ToString();
lblN6.Text = RandomClass.Next(1, 46).ToString();
btnNumbers.Text = "Get Another Set";
