如何将变量放在单个数组中 [英] How Do I Put variables In Single Array

问题描述

我有

I have

a=1,2,3;
b=20,30,40;
c=12,13,14;

如何将它们放在单个数组中

how do i put them in single array

推荐答案

可能：

Maybe:

int[] a = new int[] { 1, 2, 3 };
int[] b = new int[] { 20, 30, 40 };
int[] c = new int[] { 12, 13, 14 };
int[][] array = new int[][] { a, b, c };

您的代码示例不起作用：您不能使用像那个在C＃



但是我假设你要创建一个包含行列的数组。



如果是这样，有两种方法。

多维数组：

Your code example doesn't work: you can't use staff like that in C#

But what I assume is that you want to create an array that contains rows a columns.

If so, there are two ways.
Multidimensional array:

int[,] arr = new int[3,3];

这会创建一个总是大小相同的数组。你可以很容易地将它初始化为你的数据

This creates an array that is always the same size. You can initialise it to your data very easily

int[,] arr = new int[,] {{1,2,3}, {1,2,3}, {1,2,3}};

锯齿状阵列：

Jagged arrays:

int[][] arr = new int[3][];

这些更难初始化，但在MSDN上有一个例子：数组 [ ^ ]
