                int i = Convert.ToInt32(textBox1.Text), s,t;                for (s = 2; s <=i; s++)
                {
                    for (t = 2;t<i ;t++ )
                    {
                        if (s % t == 0)
                        {
                            break;
  
                    }                }
                if (s == t)
                {
                    listBox1.Items.Add(s);
