LINQ查询根据两个列表返回元素，并根据多个属性处理结果

// 定义两个列表
List<Person> persons = new List<Person>
{
    new Person { Id = 1, Name = "Alice" },
    new Person { Id = 2, Name = "Bob" },
    new Person { Id = 3, Name = "Charlie" }
};

List<Salary> salaries = new List<Salary>
{
    new Salary { PersonId = 1, Amount = 5000 },
    new Salary { PersonId = 2, Amount = 6000 },
    new Salary { PersonId = 3, Amount = 7000 }
};

// 使用Join操作符进行关联查询
var query = from person in persons
            join salary in salaries on person.Id equals salary.PersonId
            select new { person.Name, salary.Amount };

// 处理查询结果
foreach (var result in query)
{
    Console.WriteLine($"Name: {result.Name}, Salary: {result.Amount}");
}
