如何使用linq c#或inside泛型方法为任意一个或两个属性赋值？

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

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

public class Program
{
    public static void Main()
    {
        List<Person> people = new List<Person>
        {
            new Person { Name = "John", Age = 25 },
            new Person { Name = "Jane", Age = 30 },
            new Person { Name = "Bob", Age = 35 }
        };

        var personToUpdate = people.FirstOrDefault(p => p.Name == "John");
        if (personToUpdate != null)
        {
            personToUpdate.Age = 26;
        }

        Console.WriteLine("Updated age: " + personToUpdate.Age);
    }
}

using System;

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

public class PropertySetter<T>
{
    public void SetProperties(T obj, Action<T> propertySetter)
    {
        propertySetter(obj);
    }
}

public class Program
{
    public static void Main()
    {
        Person person = new Person { Name = "John", Age = 25 };

        PropertySetter<Person> setter = new PropertySetter<Person>();
        setter.SetProperties(person, p =>
        {
            p.Name = "Jane";
            p.Age = 30;
        });

        Console.WriteLine("Updated name: " + person.Name);
        Console.WriteLine("Updated age: " + person.Age);
    }
}
