LINQ检查列表对象的每个属性，查看它的值是否等于字符串

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

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

        string searchString = "Engineer";

        var matchingPeople = people.Where(p => p.Name == searchString || p.Age.ToString() == searchString || p.Occupation == searchString);

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