Question

How do I get the string representation if I know the enum of integer value ?

type    
  MyEnum = (tmp_one, tmp_two, tmp_three);

const
  MyTypeNames: array[tmp_one..tmp_three] of string = ('One', 'Two', 'Three');

I’m assuming that you have an ordinal value rather than a variable of this enumerated type. If so then you just need to cast the ordinal to the enumerated type. Like this:

function GetNameFromOrdinal(Ordinal: Integer): string;
begin
  Result := MyTypeNames[MyEnum(Ordinal)]; 
end;
