c# - Manage string arguments passed to function without enum -

i'm using webrequest make calls api. want make wrapper call specifies variable routing use. @ moment, can come enum , switch statement.

public void webrequestwrapper(myenum arg) {     string argument = string.empty;     switch(arg)     {         case myenum.myspecifiedargument:             argument = "myspecifiedargument";             break;         // etc etc...     }     var request = new webrequest.create(myurl + argument);     // etc, etc... } 

my question is, there way around using enum don't have use switch statement? do:

public void webrequestwrapper(myargcollection arg) {     var request = new webrequest.create(myurl + arg);     // etc, etc... } 

where myargcollection custom class/struct/something-like-an-enum , 'arg' represent string? know use reflection , enum helper classes, i've read that isn't particularly fast.

with enum, have:

enum myenum { stuff = 3, fred = 5, plant = 125 } 

whereas i'd be:

enum myenum { stuff = "things in room", fred = "a guy down street", plant = "no longer alive" } 

obviously, latter isn't legal. there way of using struct, class, whatever make work? please let me know if doesn't make sense. thanks!

update after question change: so, want attach custom string each enum value. can use attributes that:

enum myenum {     [description("things in room")]     stuff,     [description("a guy down street")]     fred,     ... } 

you'll need create descriptionattribute class, of course.

then can add extension method:

public static string getdescription(this enum e); 

this method see if enum's value has descriptionattribute, , if - return content. if not, should return e.tostring().

answer old question: can use arg.tostring() string representation.
