How can I get a name of enumerated value

For example, if you have the some enum type

TyourEnumType = (One, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten)

and you want in run-time to get a string with same value for each of them (for example, fill the combobox items with enum values), then you can use the next procedure:
uses TypInfo;

var i: Integer;
begin
  for i := Ord(Low(TyourEnumType)) to Ord(High(TyourEnumType)) do
    Combobox1.Items.Add(GetEnumName(TypeInfo(TyourEnumType), i));
end;
