比较和提取 2 个字符串之间的常用词

Question

在 ASP.NET C# 中并假设我有一个字符串包含逗号分隔的单词：

string strOne = "word,WordTwo,another word, a third long word, and so on";

如何拆分然后与可能包含或不包含这些单词的另一个段落进行比较：

string strTwo = " when search a word or try another word you may find that  WordTwo is there with others";

那么如何在第三个字符串中输出这些以逗号分隔的常用词

string strThree = "output1, output2, output3";

要得到类似的结果："word, WordTwo, another word,"

Answer 1

您需要用逗号拆分 strOne，并使用 contains 对 strTwo。

注意：你不能用空格分割 strTwo 并使用 intersect 因为你的项目可能有空格。即“另一个词”

string strOne = "word,WordTwo,another word, a third long word, and so on";
string strTwo = " when search a word or try another word you may find that  WordTwo is there with others";
var tokensOne = strOne.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

var list = tokensOne.Where(x => strTwo.Contains(x));

var result = string.Join(", ",list);

Answer 2

你可以这样做：

        string strOne = "word,WordTwo,another word, a third long word, and so on";
        string strTwo = " when search a word or try another word you may find that  WordTwo is there with others";
        string finalString = string.Empty;

        foreach (var line in strOne.Split(","))
        {
            if(strTwo.Contains(line))
                finalString += (line + ",");
        }

        finalString = finalString.Substring(0, finalString.Length - 1);
        Console.WriteLine(finalString);
