通过LINQ C＃出现单词的复杂排序列表
可能重复：
按LINQ C＃出现单词对列表进行排序
我在这里发布了一个类似的问题，并得到了一个不起作用的答案。 这是我需要排序的数据。
ID Title --- ------ 1 JCB Excavator - ECU P/N: 728/35700 2 Geo Prism 1995 Geo cart Geo001 -Geo ABS #16213899 3 Geo Prism 1995 - Geo ABS #16213899 4 Geo Prism 1995 - ABS #16213899 5 Wie man BBA reman erreicht 6 this JCB test JCB 7 Ersatz Airbags, Gurtstrammer und Auto Körper Teile 我的搜索数据类似于“JCB GEO”。 我想以这样的方式对它进行排序，使数据变得像
ID Title --- ------ 2 Geo Prism 1995 Geo cart Geo001 -Geo ABS #16213899 3 Geo Prism 1995 - Geo ABS #16213899 4 Geo Prism 1995 - ABS #16213899 6 this JCB test JCB 1 JCB Excavator - ECU P/N: 728/35700 5 Wie man BBA reman erreicht 7 Ersatz Airbags, Gurtstrammer und Auto Körper Teile
首先出现的行是数据具有最大时间的行。 所以对于GEO来说，这个词在大多数行中都有最大的时间。 ID 2有最大时间，单词GEO，下一行有2个Geo字……
我说我发布了这个问题并得到了下面的答案，这是行不通的。
List list = new List() { new SearchResult { Description = "JCB Excavator - ECU P/N: 728/35700" }, new SearchResult { Description = "Geo Prism 1995 - ABS #16213899" }, new SearchResult { Description = "Geo Prism 1995 - ABS #16213899" }, new SearchResult { Description = "Geo Prism 1995 - ABS #16213899" }, new SearchResult { Description = "Wie man BBA reman erreicht" }, new SearchResult { Description = "this test JCB" }, new SearchResult { Description = "Ersatz Airbags, Gurtstrammer und Auto Körper Teile" } }; var wordsToFind = "Geo JCB".Split(); var values = list.Select(x => new { SearchResult = x, Count = x.Description.Split(' ') .Where(c => wordsToFind .Contains(c)).Count() }) .OrderByDesending(x => x.Count) .Select(x => x.SearchResult);
也许你可以这样做？ 我用来测试的主控台程序
static void Main(string[] args) { var list = SearchResult.GetResult(); var wordArray = "Geo,JCB".Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries); list.Sort((a, b) => { int sum1 = 0, sum2=0; foreach (var item in wordArray) { sum1 += Regex.Matches(a.Description, item).Count; sum2 += Regex.Matches(b.Description, item).Count; } if (sum1 < sum2) return 1; else if (sum1 > sum2) return -1; else return 0; }); foreach (var item in list) { Console.WriteLine(item.Description); } Console.ReadKey(); }
searchresult类
public class SearchResult { public string Description { get; set; } public static List GetResult() { var list = new List () { new SearchResult(){Description = "JCB Excavator - ECU P/N: 728/35700"}, new SearchResult(){Description = "Geo Prism 1995 Geo cart Geo001 -Geo ABS #16213899"}, new SearchResult(){Description = "Geo Prism 1995 - Geo ABS #16213899"}, new SearchResult(){Description = "Geo Prism 1995 - ABS #16213899"}, new SearchResult(){Description = "Wie man BBA reman erreicht"}, new SearchResult(){Description = "this JCB test JCB"}, new SearchResult(){Description = "Ersatz Airbags, Gurtstrammer und Auto Körper Teile"} }; return list; } }
为你问的问题返回properoutput …
