Dynamically assign enumeration selection from variable

Hi, I'm pretty new at using enumerators.  I would set the value of the enumerator based on a value set in a database table.  Below is a simplified attempt to show what I'm trying to do ... I'm open to any methods to do this, doesn't have to be a switch.  I am also getting an error on the 2nd RouteMethod saying: a local variable name 'RouteMethod' is already defined in this scope.

static string method1()

//value from database
String RM = dbConfig("RouteMethod").ToString();
            switch (RM)
                case "Practical":
                    RouteType RouteMethod = RouteType.Practical;
                case "Shortest":
                    RouteType RouteMethod = RouteType.Shortest;
                case "National":
                    RouteType RouteMethod = RouteType.National;
                case "FiftyThree":
                    RouteType RouteMethod = RouteType.FiftyThree;
                case "AvoidToll":
                    RouteType RouteMethod = RouteType.AvoidToll;
                case "Air":
                    RouteType RouteMethod = RouteType.Air;
                    RouteType RouteMethod = RouteType.Practical;

Your enum declaration is missing from the example but I'm assuming it's something like this:

public Enum RouteType

If that's the case then they have integer values starting with zero. Store your value in your database as an int and do a simple cast on the way out.

RouteType RouteMethod = (RouteType)Convert.ToInt32(dbConfig("RouteMethod"))

Open in new window

If you really want to store as a string (which does make it easier to read in the database you could cast it like this:

(RouteType)Enum.Parse(typeof(RouteType), dbConfig("RouteMethod").toString());
