如何使用IEnumerable链接分拣机,每个分拣机都遵循前一个分拣机的顺序？

Question

基本上,我有一个小程序,我想在一个对象列表上执行一系列排序.每种排序都应该在对象的不同属性上运行,并遵循前一种排序产生的排序.这是我到目前为止所拥有的:

class Program
{
    static void Main(string[] args)
    {
        List<Person> people = new List<Person>();
        people.Add(new Person { Name = "John",   Age = 43 });
        people.Add(new Person { Name = "Ringo",  Age = 73 });
        people.Add(new Person { Name = "John",   Age = 32 });
        people.Add(new Person { Name = "Paul",   Age = 38 });
        people.Add(new Person { Name = "George", Age = 16 });
        people.Add(new Person { Name = "John",   Age = 80 });
        people.Add(new Person { Name = "Ringo",  Age = 22 });
        people.Add(new Person { Name = "Paul",   Age = 64 });
        people.Add(new Person { Name = "George", Age = 51 });
        people.Add(new Person { Name = "George", Age = 27 });
        people.Add(new Person { Name = "Ringo",  Age = 5 });
        people.Add(new Person { Name = "Paul",   Age = 43 });

        Print(Sort(people));
    }

    static IEnumerable<Person> Sort(IEnumerable<Person> people)
    {
        //order by name first, then order by age
        return people.OrderBy(p => p.Name).OrderBy(p => p.Age);
    }

    static void Print(IEnumerable<Person> people)
    {
        foreach (Person p in people)
            Console.WriteLine("{0} {1}", p.Name, p.Age);
    }

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

        public int Age { get; set; }
    }
}

这会产生以下输出:

Ringo 5
George 16
Ringo 22
George 27
John 32
Paul 38
John 43
Paul 43
George 51
Paul 64
Ringo 73
John 80

但我希望它产生这个输出:

George 16
George 27
George 51
John 32
John 43
John 80
Paul 38
Paul 43
Paul 64
Ringo 5
Ringo 22
Ringo 73

换句话说,我希望它按顺序排序Name,然后Age在每个Name"组" 内执行本地化排序.显然,Sort()到目前为止我所使用的方法并没有这样做,它只执行两个链接OrderBy.

我能做到这一点的最佳方式是什么IEnumerable？理想情况下,我希望扩展和支持尽可能多的链式排序的解决方案,每种类型产生一组"组",下一个分类器必须将其排序本地化.

尝试使用它应重新排序而不破坏第一个订单

return people.OrderBy(p => p.Name).ThenBy(p => p.Age);
