使用IQueryable从类中选择字段

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Address { get; set; }
}

public static void Main()
{
    List<Person> people = new List<Person>
    {
        new Person { Name = "Alice", Age = 25, Address = "123 Main St" },
        new Person { Name = "Bob", Age = 30, Address = "456 Elm St" },
        new Person { Name = "Charlie", Age = 35, Address = "789 Oak St" }
    };

    IQueryable<Person> queryablePeople = people.AsQueryable();

    var result = queryablePeople.Select(p => new { p.Name, p.Age });

    foreach (var person in result)
    {
        Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");
    }
}
