是否有一个C#库提供像numpy这样的数组操作 [英] Is there a c# library that provides array manipulation like numpy

问题描述

我开始使用Numpy，非常喜欢它的数组处理功能.我可以在C#中使用一些库来为数组提供类似的功能.我最想要的功能是:

I am starting to use the Numpy and really like it's array handling capabilities. Is there some library that I can use in C# that provides similar capabilities with arrays. The features I would like most are:

• 从另一个阵列创建一个阵列
• n维数组的简单/遍历迭代
• 切片数组

推荐答案

我认为您不需要图书馆.我认为LINQ可以很好地提及您.

I don't think you need a library. I think LINQ does all you mention quite well.

int[,] parts = new int[2,3];

int[] flatArray = parts.ToArray();
// Copying the array with the same dimensions can easily be put into an extension 
// method if you need it, nothing to grab a library for ...

轻松迭代

int[,] parts = new int[2,3];

foreach(var item in parts)
    Console.WriteLine(item);

数组切片

int[] arr = new int[] { 2,3,4,5,6 };
int[] slice = arr.Skip(2).Take(2).ToArray();

// Multidimensional slice 
int[,] parts = new int[2,3];
int[] slice = arr.Cast<int>().Skip(2).Take(2).ToArray();

最后一个示例中的尴尬.Cast<int>是奇怪的是，C#中的多维数组只是IEnumerable而不是IEnumerable<T> .

The awkward .Cast<int> in the last example is due to the quirk that multidimensional arrays in C# are only IEnumerable and not IEnumerable<T>.
