c# LINQ筛选器嵌套集合

    new Person { Name = "Charlie", Age = 35, Hobbies = new List<string> { "Reading", "Swimming" } }
};

// 使用查询表达式筛选年龄大于30岁且爱好包含"Reading"的人
var query = from person in people
            where person.Age > 30 && person.Hobbies.Contains("Reading")
            select person;

// 使用方法语法筛选年龄大于30岁且爱好包含"Reading"的人
var query = people.Where(person => person.Age > 30 && person.Hobbies.Contains("Reading"));

foreach (var person in query)
