27             var list = personList.Where(d => d.Age.Equals(personList.Where(e => e.Sex == "?").Max(e => e.Age))).ToList();
28 
29             foreach (var v in list)
30             {
31                 Console.WriteLine(v.Name + "--" + v.Age + "--" + v.Sex);
32             }
33 
34             Console.ReadLine();
35         }
36     }
37 }
