c# - 如何实现简单的字符串搜索

Question

我想根据我的搜索查询在我的应用程序中实现一个简单的搜索。假设我有一个包含 2 个段落或文章的数组，我想在这些文章中搜索我输入的相关主题或相关关键字。

例如:

//this is my search query
string mySearchQuery = "how to play with matches";

//these are my articles
string[] myarticles = new string[] {"article 1: this article will teach newbies how to start fire by playing with the awesome matches..", "article 2: this article doesn't contain anything"};

如何根据上面提供的搜索查询获取第一篇文章？有什么想法吗？

Answer 1

这将返回 myarticles 中包含 mysearchquery 中所有单词的任何字符串:

var tokens = mySearchQuery.Split(' ');
var matches = myarticles.Where(m => tokens.All(t => m.Contains(t)));

foreach(var match in matches)
{
    // do whatever you wish with them here
}
