Random rnd = new Random(); int month  = rnd.Next(1, 13);  // creates a number between 1 and 12 int dice   = rnd.Next(1, 7);   // creates a number between 1 and 6 int card   = rnd.Next(52);     // creates a number between 0 and 51

var random = new Random(); int randomnumber = random.Next() 

using (RNGCryptoServiceProvider rg = new RNGCryptoServiceProvider())  {      byte[] rno = new byte[5];         rg.GetBytes(rno);         int randomvalue = BitConverter.ToInt32(rno, 0);  }
