在没有For循环的情况下在Linq中配对集合(Pairing Collections in Linq without a For Loop)

在没有For循环的情况下在Linq中配对集合(Pairing Collections in Linq without a For Loop)

我有两个集合

int[] numbers = {5, 2, 1, 5}; string[] words = {"flibble", "bobble", "double", "dumble"};

我想在第二个集合上使用第一个linq表达式。 使用循环，我会做下面的事情

List<string> results = new List<string>(); for(int i = 0; i<numbers.Count(), i++) { results.Add(words[i].SubString(numbers[i]); } return results;

然而，这涉及到创建一个没有真正原因的列表......有没有办法在Linq中做到这一点？

I have two collections

int[] numbers = {5, 2, 1, 5}; string[] words = {"flibble", "bobble", "double", "dumble"};

I want to use a linq expression on the second collection using the first. Using a loop I'd do the following

List<string> results = new List<string>(); for(int i = 0; i<numbers.Count(), i++) { results.Add(words[i].SubString(numbers[i]); } return results;

However this involves creating a list for no real reason... is there a way to do this in Linq?

我猜你正在寻找Enumerable.Zip() ：

numbers.Zip(words, (n, w) => w.Substring(n));

I'm guessing you're looking for Enumerable.Zip():

numbers.Zip(words, (n, w) => w.Substring(n));
