Why can't I get this random number generating form to work? it already has the dll file system.data using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace WindowsFormsApp3 { public partial class Form1 : Form { Random Ran = new Random(); int value; public Form1() { InitializeComponent(); } private void Button1_Click(object sender, EventArgs e) { value = Ran.Next(1, 69); label1.Text = value.ToString(); } } }
