通过多维数组作为德尔福参数 [英] Pass a multidimensional array as a parameter in Delphi

问题描述

我想一个多维数组传递给构造函数，像这样：

I'd like to pass a multi-dimensional array to a constructor like so:

constructor TMyClass.Create(MyParameter: array of array of Integer);
begin
  LocalField := MyParameter;
end;

在哪里LocalField是整型数组的数组。

Where LocalField is an array of array of Integer.

不过上述code不会编译（'标识，但却发现ARRAY'）。可能有人向我解释为什么这是错的？我试过在开放，动态和静态数组读了，但还没有找到一些作品。有没有办法解决它在不改变LocalField的类型？

However the above code won't compile ('Identifier expected but ARRAY found'). Could somebody explain to me why this is wrong? I tried reading up on open, static and dynamic arrays but have yet to find something that works. Is there a way to fix it without changing the type of LocalField?

推荐答案

请为localfield一个特定的类型，然后设置，作为MyParameter的类型，沿着线的东西：

Make a specific type for localfield, then set that as the type of MyParameter, something along the lines of:

type
  TTheArray = array[1..5] of array[1..10] of Integer;

var
  LocalField: TTheArray;

constructor TMyClass.Create(MyParameter: TTheArray);
...

（注：在编译器中不核实，小错误可能是present）

(Note: not verified in a compiler, minor errors may be present)

请注意，大部分经常在帕斯卡的语法多维数组更正确地声明为

Note that most often in pascal-like syntax a multidimensional array is more properly declared as

type
  TTheArray = array[1..5, 1..10] of Integer;

当然，除非，你有一些很好的理由这样做的其他方式。

Unless, of course, you have some good reason for doing it the other way.
