如何使用LINQ在字符串[]中找到最长的字符串 [英] how to find the longest string in a string[] using LINQ

问题描述

我有一个可变长度的字符串数组。目前我有一个循环遍历数组，找到数组中最长的字符串。有没有什么办法我可以使用LINQ以更高效和/或更清晰的方式写它？

I have an array of strings of variable length. Currently I have a loop that iterates through the array to find the longest string in array. Is there any way I could use LINQ to write it in more efficient and / or cleaner way?

推荐答案

更高效，但是做一些更干净的事情：

It won't be much more efficient, however it would be a bit cleaner to do something like:

var strings = new string[] { "1", "02", "003", "0004", "00005" };

string longest = strings.OrderByDescending( s => s.Length ).First();

输出：00005
