理解 Delphi 的类(十) - 深入方法[12] - implementation 区中的方法

//要点12: implementation 区中的过程或函数, 只能在本单元调用
unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
end;

var
Form1: TForm1;

implementation

{$R *.dfm}

{implementation 区中的过程或函数, 只能在本单元调用}
function MyFun(x,y: Integer): Integer;
begin
Result := x + y;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
i: Integer;
begin
i := MyFun(1,2);
end;

end.
