需要从对象列表中返回具有最低属性值的对象

Question

我有一个客户列表，如下所示：

var customers = new List<Customer>
{
    new Customer { Name = "John", Age = 20 },
    new Customer { Name = "Adam", Age = 30 },
    new Customer { Name = "Joi", Age = 26 }
};

退回年龄最低的客户对象的最佳方式是什么？

Answer 1

这是最有效的方法：

var customers = new List<Customer>
{
    new Customer { Name = "John", Age = 20 },
    new Customer { Name = "Adam", Age = 30 },
    new Customer { Name = "Joi", Age = 26 }
};

var youngest = customers.Aggregate((x, y) => x.Age < y.Age ? x : y);

这给了我：

或者，现在使用 .NET 6.0：

var youngest = customers.MinBy(c => c.Age);
