[英]Linq query with OrderBy word count
I have this bit of code,我有这段代码,
public static List<string> GetSentencesFromWords(List<string> words, string fileContents)
{
return fileContents.Split('.')
.Where(s => words.Any(w => s.IndexOf(w) != -1))
.Select(s => s.TrimStart(' ') + ".")
.ToList();
}
It works brilliantly, another user helped me with it in another question, but I thought my new question related to it warranted a new post.它工作得很好,另一个用户在另一个问题中帮助我解决了这个问题,但我认为与它相关的新问题需要一个新帖子。 I need the returned word list to be ordered by the number of matches in each sentence.我需要返回的单词列表按每个句子中的匹配数排序。 I have tried to do it a few ways but I am not very experienced with Linq and everything I have tried just seems to sort by sentence length rather than word count.我尝试过几种方法,但我对 Linq 不是很有经验,我尝试过的所有内容似乎都是按句子长度而不是字数排序。
Try this and it should work for you?试试这个,它应该适合你?
return fileContents.Split('.')
.Where(s => words.Any(w => s.IndexOf(w) != -1))
.Select(s => s.TrimStart(' ') + ".")
.OrderByDescending(s => words.Count(w => s.IndexOf(w) != -1))
.ToList();
What about this:那这个呢:
return fileContents.Split('.')
.Where(s => words.Any(w => s.Contains(w) != -1))
.Select(s => s.TrimStart(' ') + ".")
.OrderByDescending(s => words.Sum(w => Regex.Matches(s, w).Count))
.ToList();
don't forget to include using System.Text.RegularExpressions
不要忘记using System.Text.RegularExpressions
