我如何初始化INT [] []？ [英] How do i initialize int[][]?

问题描述

在C＃中我如何初始化

int[][] test;

我不希望使用 INT [，] 来代替。我问具体怎么初始化以上。最明显的 = INT [1] [1] 不起作用。我试过，没有运气了几个不同的方式和[] []是不是真的谷歌能够很遗憾（除非其可能！？）

I don't want to use int[,] instead. I am asking specifically how to initialize the above. The obvious = int[1][1] does not work. I tried a few different ways with no luck and [][] is not really google-able unfortunately (unless its possible!?)

推荐答案

这就是所谓的交错数组的，如果你想google一下。

It's called jagged arrays if you want to Google it.

基本上你可以用传统的方式初始化第一维：

Basically you can initialize the first dimension in the traditional way :

int[][] test = new int[23][];

和手动初始化其他：

for (int i = 0; i < test.Length; ++i)
    test[i] = new int[42];
