如何使用linq基于类型的动态选择

using System;
using System.Linq;

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

public class Animal
{
    public string Name { get; set; }
    public string Species { get; set; }
}

public static class Program
{
    public static void Main()
    {
        // 创建对象集合作为数据源
        var data = new object[]
        {
            new Person { Name = "Alice", Age = 25 },
            new Animal { Name = "Tom", Species = "Cat" },
            new Person { Name = "Bob", Age = 30 },
            new Animal { Name = "Jerry", Species = "Mouse" }
        };

        // 构建LINQ查询表达式，根据类型进行动态选择
        var query = data.Select(item =>
        {
            if (item.GetType() == typeof(Person))
            {
                var person = (Person)item;
                return $"Person: {person.Name}, Age: {person.Age}";
            }
            else if (item.GetType() == typeof(Animal))
            {
                var animal = (Animal)item;
                return $"Animal: {animal.Name}, Species: {animal.Species}";
            }
            else
            {
                return "Unknown type";
            }
        });

        // 执行查询并输出结果
        foreach (var result in query)
        {
            Console.WriteLine(result);
        }
    }
}
