双[，]类型，如何让行＃？ [英] double[,] type, how to get the # of rows?

问题描述

我似乎得到一个奇怪的值。

I seem to be getting an odd value.

我如何得到我的阵列中的行数：

How do I get the number of rows in my array:

double[,] lookup = { {1,2,3}, {4,5,6} };

输出应为2。

推荐答案

查找有两个维度，这就是你如何阅读

lookup has two dimensions, this is how you read them

double[,] lookup = { {1,2,3}, {4,5,6} };

int rows = lookup.GetLength(0); // 2
int cols = lookup.GetLength(1); // 3    
int cells = lookup.Length; // 2*3 = 6

在行和 COLS 的概念只是传统，你也可以同样拨打第一维列。

The rows and cols concept is just tradition, you could just as well call the first dimension the columns.
