delphi 友元类

 在一个单元中声明的多个类互为友元类
type
TMyClass = class
GUID: string;
Name: string;
bSex: Boolean;
Tel : string;
end;
TForm1 = class(TForm)
Button1: TButton;
Memo1: TMemo;
Button2: TButton;
procedure Button2Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
FName: string;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button2Click(Sender: TObject);
var
obj: TMyClass;
begin
obj := TMyClass.Create;
obj.Name := Form1.FName;
ShowMessage(obj.Name);
obj.Free;
end;
procedure TForm1.FormCreate(Sender: TObject);
begin
FName := '兵临成下';
end;
结果如下：
