任何人都可以解释下面的代码是怎么回事？ [英] can anyone explain what going on with the follwing code?

问题描述

以下代码是做什么的

what is the following code doing

int[] lstNumbers = p.RandomNumbers();
                       int[,] array = new int[3, 3];

此方法

in this method

int k = 1;
                        int[] lstNumbers = p.RandomNumbers();
                        int[,] array = new int[3, 3];

                        for (int i = 0; i < 3; i++)
                        {
                            for (int j = 0; j < 3; j++)
                            {
                                array[i, j] = lstNumbers[k - 1];
                                k++;
                            }

                        } 

实际上我只是想知道int [，] array = new int [3,3]



它会创建一个3行和3列矩阵，但为什么我们写int [，] ??

actually i just want to know int[,] array =new int [3,3]

it will create a 3 row and 3 columns matrix but why we write int[,]??

推荐答案

也许你应该看看MSDN。

int i [，] 告诉编译器它是一个具有两个维度的多维数组。

然后在下一部分 new int [3,3 ] 你告诉编译器每个维度的长度。

这样简单。

Maybe you should take a look at MSDN.

http://msdn.microsoft.com/en-us/library/2yd9wwz4.aspx[^]

int i[,] tells the compiler that it is a multi dimensional array with two dimensions.
Then in the next part new int [3,3] you tell the compiler the length of each dimension.
Simple as that.
