如何在LINQ中重新映射属性？

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        List<Student> students = new List<Student>
        {
            new Student { Id = 1, Name = "张三", Age = 20 },
            new Student { Id = 2, Name = "李四", Age = 22 },
            new Student { Id = 3, Name = "王五", Age = 21 }
        };

        var result = students.Select(s => new { s.Id, s.Name, s.Age });

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

class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        List<Student> students = new List<Student>
        {
            new Student { Id = 1, Name = "张三", Age = 20 },
            new Student { Id = 2, Name = "李四", Age = 22 },
            new Student { Id = 3, Name = "王五", Age = 21 }
        };

        var result = students.Select(s => new StudentDTO { Id = s.Id, Name = s.Name, Age = s.Age });

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

class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}

class StudentDTO
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}
