Execute code from string?

I know the code below fails, but can anyone provide a solution to concatonate the eDamage string & execute the randomly selected aircraft.hitNamed(part.NamedDamageTypes. line?

Code:

string[] eDamage = 

        {

            "ElecBatteryFailure",

            "ElecGeneratorFailure",

            "ElecIlluminationFailure",

            "ElecMasterCompassFailure",

            "ElecPrimaryFailure",

            "ElecPriNavigationFailure",

            "ElecSecNavigationFailure",

            "ElecSecondaryFailure",

            "ElecTransceiverFailure",

            "ElecWeaponryFailure"

            };



            // ---- Electrics failures ----=

            string e = "aircraft.hitNamed(part.NamedDamageTypes." + eDamage[random.Next(eDamage.GetLowerBound(0), eDamage.GetUpperBound(0) + 1)] + ");";

            //Console.WriteLine(e);

            //Process.Start(e);

            // string e conatins the c# code, now how to 'execute' the string as a command?

        }

Prozess.Start is for starting external programms for example:
Process.Start("http://google.com/search?q= Help me");
would start your browser with a google search for "Help me".

Its not for execute little c# snippets ;).

Yeah, I know Kodiak. I've seen somewhere on the forums a code snippet demonstrating what I'm looking for, but I can't find it again (damn) :)

These?:

Code:

 private void damageAiControlledPlane(AiActor actorMain)

    {

        foreach (AiActor actor in actorMain.Group().GetItems())

        {

            if (actor == null || !(actor is AiAircraft))

                return;



            AiAircraft aircraft = (actor as AiAircraft);



            if (!isAiControlledPlane(aircraft))

                return;



            if (aircraft == null)

                return;



            aircraft.hitNamed(part.NamedDamageTypes.ControlsElevatorDisabled);

            aircraft.hitNamed(part.NamedDamageTypes.ControlsAileronsDisabled);

            aircraft.hitNamed(part.NamedDamageTypes.ControlsRudderDisabled);

            aircraft.hitNamed(part.NamedDamageTypes.FuelPumpFailure);



            int iNumOfEngines = (aircraft.Group() as AiAirGroup).aircraftEnginesNum();

            for (int i = 0; i < iNumOfEngines; i++)

            {

                aircraft.hitNamed((part.NamedDamageTypes)Enum.Parse(typeof(part.NamedDamageTypes), "Eng" + i.ToString() + "TotalFailure"));

            }





            Timeout(300, () =>

            { destroyPlane(aircraft); }

                );

        }

    }

I think you might have to list the items in a list then random select an item(line by number) to use. This may however have a parse problem where you are transfering built in code to string types(listing) and back again.(am I sick of parsing problems yes I am)

might have some syntax errors in the following, but something like, (yes this came from Kodiak :))

Code:



List<Damage> DamageList = new List<Damage>

{

    new Damage ("ElecBatteryFailure"),

    new Damage ("ElecGeneratorFailure")

// add each damage type(note add comma on preceeding line)



};



    internal class Damage 

   {

        public string EDamageType { get; set; }

        public Damage(string eDamageType)

       {

            this.EDamageType = eDamageType;

       }

   }





//random selection

Random rand = new Random();          



int i = 0;

if (DamageList.Count > 0)

i = rand.Next(0, DamageList.Count);

aircraft.hitNamed(part.NamedDamageTypes.DamageList[i].EDamageType);

});
