在Delphi中定义其他单位的类型 [英] Defining types from other units in Delphi

问题描述

Var
     A : Array [1..4] of Integer;
     B : Array [1..4] of Integer;

Begin
    A := B;

不会像loren-pechtel所说的那样工作

Won't work as loren-pechtel said here the problem is A and B for me are in different units. So, is there a way to define a type definition from a existing one in another class?

推荐答案

在某个单元的接口块中定义类型，然后通过uses子句将该单元包括在需要该类型的其他单元中.

Define type in interface block of some unit and then include that unit via uses clause in other units where you need that type.

unit A;
interface
type
  TMyArray = array [1..4] of Integer;

...

当您需要在另一单元中使用TMyArray时:

When you need to use TMyArray in another unit:

unit B;
interface
uses A;

...
var x : TMyArray;
