I want to use a switch statement in order to avoid many if's. So I did this:

        public enum Protocol
        {
             Http,
             Ftp
        }

        string strProtocolType = GetProtocolTypeFromDB();

        switch (strProtocolType)
        {
            case Protocol.Http:
                {
                    break;
                }
            case Protocol.Ftp:
                {
                    break;
                }
        }

but I have a problem of comparing an Enum and a String. So if I added Protocol.Http.ToString() there is another error because it allows only CONSTANT evaluation. If I change it to this

        switch (Enum.Parse(typeof(Protocol), strProtocolType))

It's not possible also. So, it's possible to use in my case a switch statement or not?
