如何比较 C# 中的多维数组?

How to compare multidimensional arrays in C# ?(如何比较 C# 中的多维数组?)

问题描述

如何比较多维数组?只是真/假.

How to compare multidimensional arrays? Just true/false.

double[,] data1 = new double[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };    
double[,] data2 = new double[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };

//bool compare = data1.SequenceEqual(data2);

有没有办法像一维数组一样比较二维数组?

Is there way to compare 2d arrays like 1d array ?

data1.SequenceEqual(data2);     

我必须每秒比较，所以最简单的方法会很棒.非常感谢.

I have to compare every second, so easiest way will be great. Thanks a lot.

推荐答案

多维数组可以在 linq 中作为一维枚举使用.您只需要检查所有尺寸的长度.这个片段应该足够了:

A multidimensional array can be used in linq as one dimensional enumerable. You just need to check also for the length of all dimensions. This snippet should be enough:

var equal =
    data1.Rank == data2.Rank &&
    Enumerable.Range(0,data1.Rank).All(dimension => data1.GetLength(dimension) == data2.GetLength(dimension)) &&
    data1.Cast<double>().SequenceEqual(data2.Cast<double>());
