Question

在ASP.NET C＃中假设我的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";

如何拆分然后与另一个可能包含或不包含这些词的段落进行比较：

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

然后如何输出这些常用词在第三个字符串中以逗号分隔

string strThree = "output1, output2, output3";

获得如下结果：＆＃34; word，WordTwo，另一个词，＆＃34;

Answer 1

您需要用逗号拆分 strOne，并对strTwo使用包含。

注意：您无法按空格分割strTwo并使用相交，因为您的项目可能包含空格。即＆＃34;另一个词＆＃34;

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);
