二维数组初始化 [英] Two dimensional array initialization

问题描述

我可以做一个简单的初始化工作：


Object [，] ONE_ROW = {{" Vodafone" ;，5550160100197016}};


但是，现在我想创建另一个包含ONE_ROW的多个副本的数组（不会编译）：


Object [，] TWO_ROWS = {ONE_ROW，ONE_ROW}; //在Java中工作;-)

这会产生结构不正确的数组初始值设定项!!


但是，这是正确的使用硬编码数据的实现：


Object [，] TWO_ROWS = {{" Vodafone"，" 5550160100197016"}，{" Vodafone"，" 5550160100197016"}} ;


有什么想法吗？


问候，

Dadi。

听起来你想要锯齿状阵列，而不是矩形

阵列。如果你这样做：


Object [] [，] TWO_ROWS = {ONE_ROW，ONE_ROW};我相信它会工作的。


（虽然哈文没试过......）

< blockquote>其实Jon我认为他想要


Object [] [] TWO_ROWS =


a jagged ONE_ROW数组的数组。你的代码将是一个参差不齐的2D

矩形阵列，我认为这不是意图，不是吗？


我'我之前对阵列的错误也许是错的。

我不喜欢不知道 - 意图不是很清楚！但是，我的代码将会给出一个2D矩形阵列数组。

Hi,

I can make a simple initialization work like this:

Object[,] ONE_ROW = {{"Vodafone", "5550160100197016"}};

But, now I want to create another array that consists of multiple copies of ONE_ROW like this (will not compile):

Object[,] TWO_ROWS = {ONE_ROW, ONE_ROW}; // Works in Java ;-)

This yields "Incorrectly structured array initializer"!!

This, however, is a correct implementation using hard-coded data:

Object[,] TWO_ROWS = {{"Vodafone", "5550160100197016"}, {"Vodafone", "5550160100197016"}};

Any ideas?

Regards,
Dadi.

It sounds like you want jagged arrays then, rather than rectangular
arrays. If you do:

Object[][,] TWO_ROWS = {ONE_ROW, ONE_ROW}; I believe it''ll work.

(Haven''t tried it though...)

Actually Jon I think he wants

Object[][] TWO_ROWS =

a jagged array of ONE_ROW arrays. Your code would be a jagged array of 2D
rectangular arrays which I don''t think was the intent, wouldn''t it?

I''ve been wrong about arrays before so maybe I am again.

I don''t know - the intent wasn''t very clear! However, my code would
give a single array of 2D rectangular arrays.
