如何检查字符串列表是否与短语中的所有单词匹配？

Question

我有一个字符串

string[] arr = new string[] { "hello world", "how are you", "what is going on" }; 

的名单，我需要检查，如果我给字符串使用的每一个字中的一个字符串在arr

让我们说，我有

string s = "hello are going on"; 

这将是一个匹配，因为s中的所有单词都在arr

string s = "hello world man" 

这个人会不会是一个比赛，因为“人”是不是在任何字符串的arr

我知道怎么写了“长”的方式来做到这一点，但有一个很好的LINQ查询，我可以写吗？

Answer 1

string[] arr = new string[] { "hello world", "how are you", "what is going on" }; 
string s = "hello are going on"; 
string s2 = "hello world man"; 
bool bs = s.Split(' ').All(word => arr.Any(sentence => sentence.Contains(word))); 
bool bs2 = s2.Split(' ').All(word => arr.Any(sentence => sentence.Contains(word))); 

Answer 2

 string[] arr = new string[] { "hello world", "how are you", "what is going on" }; 

     HashSet<string> incuded = new HashSet<string>(arr.SelectMany(ss => ss.Split(' '))); 

     string s = "hello are going on"; 
     string s2 = "hello world man"; 

     bool valid1 = s.Split(' ').All(ss => incuded.Contains(ss)); 
     bool valid2 = s2.Split(' ').All(ss => incuded.Contains(ss)); 

享受！ （我用的服务表现哈希集，你可以取代 “i​​ncuded”（愚蠢的错误）与arr.SelectMany（SS => ss.Split（”“）），独特的（）在所有情况下。

Answer 3

我尽我所能一行:)

var arr = new [] { "hello world", "how are you", "what is going on" }; 

var check = new Func<string, string[], bool>((ss, ar) => 
    ss.Split(' ').All(y => ar.SelectMany(x => 
     x.Split(' ')).Contains(y))); 

var isValid1 = check("hello are going on", arr); 
var isValid2 = check("hello world man", arr);
