請教各位 如何將 Array 的資料存檔 成員包含Tcomponent 的 Object

參考: I need to save a array of record variable. Which is the  best way to do it? It's possible read the file with data-aware component?     A: It's not very Delphi-like (but then, neither are Pascal  records really), but you can read and write records to  and from a file using the standard Pascal file manipulation  procedures like so:

type
  TMyRec = record ;
    Field1 : integer ;
    Field2 : string ;
  end ;      TMyRecArray = array [0..9] of TMyRec ;    var
  MyArray : TMyRecArray ;
  MyRec : TMyRec ;
  RecFile : file of TMyRec ;
begin
  {...some code that intializes MyArray goes here...}
  AssignFile( RecFile, 'MYREC.FIL' ) ;
  ReWrite( RecFile ) ;
  for i := 0 to 9 do
  begin
    Write( RecFile, MyRec[i] ) ;
  end ;
  CloseFile( RecFile ) ;
end;

You can also use Read() to get a record from such a file, and Seek() to move to a particular record in the file (starting with 0). For more details on these have a look at I/O Routines in the Delphi on-line help. If you want to do this with the Data Aware components, you'll have to construct a database where the database records reflect the structure of your Pascal records, then provide translation routines to get the data from one to the other. I'm not aware of any way to do this directly, but it could certainly be encapsulated in a component.
