比较两个字符串并得到差异 [英] Compare two strings and get the difference

问题描述

我如何比较c＃中的两个字符串并获得差值？

How can i compare two strings in c# and gets the difference?

例如：

String1 ：我有车

String1 : i have a car

字符串2：我有新车宝马

string2 : i have a new car bmw

结果：新车，宝马

推荐答案

您需要确保较大的集合位于例外（不确定是否可以通过纯Linq方式实现）：

You need to make sure the larger set is on the left hand side of the Except (not sure if there is a pure Linq way to achieve that):

    static void Main(string[] args)
    {
        string s1 = "i have a car a car";
        string s2 = "i have a new car bmw";

        List<string> diff;
        IEnumerable<string> set1 = s1.Split(' ').Distinct();
        IEnumerable<string> set2 = s2.Split(' ').Distinct();

        if (set2.Count() > set1.Count())
        {
            diff = set2.Except(set1).ToList();
        }
        else
        {
            diff = set1.Except(set2).ToList();
        }
    }
