List<string> features = new List<string>(new string[] { "battery", "screen", "audio" }); 

Answer 1

的LINQ Any与Contains这个应该

List<string> features = new List<string>(){ "battery", "screen", "audio" }; 
List<string> sentences = new List<string>() { "this is a new screen", "i need a new battery", "there is no foo in my bar" }; 
List<string> result = sentences.Where(x => features.Any(y => x.Contains(y))).ToList(); 

Answer 2

您可以使用linq。

List<string> features = new List<string>(new string[] { "battery", "screen", "audio" }); 
// or simpler 
//List<string> features = new List<string>{ "battery", "screen", "audio" }; 

List<string> listOfLines = GetAllLinesHereInList(); 
var filteredLines = listOfLines.Where(ln=>features.Any(f=>ln.IndexOf(f) > -1));
