如何在c#中生成2种情况而不是1种情况

我正在尝试生成2个案例。我想让它选择2种情况

my code

#region IronTiger Boss
            if (Owner.Name == "IronTiger")
            {
                byte times = (byte)Kernel.Random.Next(1, 3);
                byte ref_times = (byte)Kernel.Random.Next(1, 6);
                for (byte i = 0; i < times; i++)
                {
                    uint Uid = 0;
                    byte type = (byte)Kernel.Random.Next(1, 28);
                    switch (type)
                    {
                        case 1:
                            Uid = 824020;

                    {
                        killer.Owner.Inventory.Add(Uid, 0, 1);
                        DeadPool.Kernel.SendWorldMessage(new DeadPool.Network.GamePackets.Message("Congratulations! " + killer.Name + " has killed " + Name + " and dropped! " + Database.ConquerItemInformation.BaseInformations[Uid].Name + "!", System.Drawing.Color.White, 2011), Program.Values);
                        return;
                    }    
                }
            }
            #endregion  

当它完成时，它只给我一个case。我想让它生成2种情况，而不是1种。我怎么能解决这个问题，也，我如何添加更多的情况?

if (Uid != 0)
{
  killer.Owner.Inventory.Add(Uid, 0, 1);
  DeadPool.Kernel.SendWorldMessage(new DeadPool.Network.GamePackets.Message("Congratulations! " + killer.Name + " has killed " + Name + " and dropped! " + Database.ConquerItemInformation.BaseInformations[Uid].Name + "!", System.Drawing.Color.White, 2011), Program.Values);
  return;
}
