How to access record properties?

问题

I need to access, record properties, and set/get this property values. Firstly, i want to access properties. But i can't.

What is wrong? Ver : Delphi XE6.

sample code:

type
  TmyRecord = record
  private
    Str : String;
  public
    property StrProp :String read Str;  
  end;


procedure TForm1.Button3Click(Sender: TObject);
var
 c : TRttiContext;
 t : TRttiType;
 field : TRttiField;
 prop : TRttiProperty;
begin
 c := TRttiContext.Create;
 try
   Memo1.Lines.Append('Fields');
   for field in c.GetType(TypeInfo(TMyRecord)).GetFields do
   begin
     t := field.FieldType;
     Memo1.Lines.Append('Field:'+field.Name);
     Memo1.Lines.Append('RttiType:'+t.ClassName);
   end;

   Memo1.Lines.Append('Properties');
   for prop in c.GetType(TypeInfo(TMyRecord)).GetProperties do
   begin
     t := prop.PropertyType;
     Memo1.Lines.Append('Property:'+prop.Name);
     Memo1.Lines.Append('RttiType:'+t.ClassName);
   end;

 finally
   c.Free
 end;

end;

Your problem is that there is no RTTI available for record properties as already reported in 2009 but still not fixed (QC#78110).

Edit: And still not fixed in 2017 (RSP-19303).
