You may define your enum like so and use cast where needed        public enum MyEnum       VariablePeriods   1      FixedPeriods   2     Usage  public class Entity       public MyEnum Property   get  set       var returnedFromDB   1  var entity   new Entity    entity Property    MyEnum returnedFromDB

You can do inline ifs with  return y    20   1   2    which will give you 1 if true and 2 if false

The literal answer is   return  value    1   Periods VariablePeriods   Periods FixedPeriods     Note that the inline if statement  just like an if statement  only checks for true or false  If  value    1  evaluates to false  it might not necessarily mean that value    2  Therefore it would be safer like this   return  value    1       Periods VariablePeriods        value    2           Periods FixedPeriods           Periods Unknown      If you add more values an inline if will become unreadable and a switch would be preferred   switch  value    case 1      return Periods VariablePeriods  case 2      return Periods FixedPeriods      The good thing about enums is that they have a value  so you can use the values for the mapping  as user854301 suggested  This way you can prevent unnecessary branches thus making the code more readable and extensible
