C# 创建一个数组数组 [英] C# Creating an array of arrays

问题描述

我正在尝试创建一个将使用重复数据的数组，如下所示:

I'm trying to create an array of arrays that will be using repeated data, something like below:

int[] list1 = new int[4] { 1, 2, 3, 4 };
int[] list2 = new int[4] { 5, 6, 7, 8 };
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[,] lists = new int[4, 4] {  list1 ,  list2 ,  list3 ,  list4  };

我无法让它工作，所以我想知道我是否在处理这个错误.

I can't get it to work and so I'm wondering if I'm approaching this wrong.

我试图做的是创建某种方法来创建一长串值，以便我可以按特定顺序重复处理它们.类似的东西，

What I'm attempting to do is create some sort of method to create a long list of the values so I can process them in a specific order, repeatedly. Something like,

int[,] lists = new int[90,4] { list1, list1, list3, list1, list2, (and so on)};

for (int i = 0; i < 90; ++i) {
   doStuff(lists[i]);
}

并将数组按顺序传递给 doStuff().我这样做是完全错误的，还是我在创建数组数组时遗漏了什么?

and have the arrays passed to doStuff() in order. Am I going about this entirely wrong, or am I missing something for creating the array of arrays?

推荐答案

你需要做的是:

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[][] lists = new int[][] {  list1 ,  list2 ,  list3 ,  list4  };

另一种选择是创建一个 List 类型:

Another alternative would be to create a List<int[]> type:

List<int[]> data=new List<int[]>(){list1,list2,list3,list4};
