Answer:

1   { ... }
2   var
3     XObject: TObject;
4     XProps: PPropList;
5     XPropInfo: PPropInfo;
6     XTypeData: PTypeData;
7     XPropsStr: string;
8     i: integer;
9     { ... }
10  begin
11    { ... }
12    XObject := OneOfYourComponents;
13    XTypeData := TypInfo.GetTypeData(XObject.ClassInfo);
14    XPropsStr := '';
15    GetMem(XProps, XTypeData^.PropCount * sizeof(Pointer));
16    try
17      TypInfo.GetPropInfos(XObject.ClassInfo, XProps);
18      for i := 0 to XTypeData.PropCount - 1 do
19      begin
20        XPropInfo := XProps[i];
21        if Assigned(XPropInfo) then
22        begin
23          if XPropInfo.PropType^^.Kind in [tkString, tkLString, tkWString] then
24            XPropsStr := XPropsStr + XProps[i].Name + ' = ' +
25              GetStrProp(XObject, XProps[i].Name) + #$0D#$0A;
26        end;
