c# – 如何根据排序进行排序

items : [{id:1,...},{id:2,{id:3,...}]

并订购：[2,3,1]得到一个可枚举

items : [{id:2,{id:1,...}]

我期望它是一个东西

items.Select(o => new {key = ordering[i++],value = o})
     .OrderBy(k => k.key)
     .Select(o => o.value)

但是有没有更清洁的解决方案？

以下我已经验证了这项工作(HimBromBeere,Domysee,qxg)

var expectedOrder = ordering.Select(x => result.First(o => o.Id == x));
var expectedOrder = result.OrderBy(item => Array.FindIndex(ordering,i => i == item.Id));
var expectedOrder = result.OrderBy(item => ordering.ToList().FindIndex(i => i == item.Id));
var expectedOrder = 
  from o in ordering
  join i in result 
    on o equals i.Id
  select i;

Fwi,这是验证测试：

[Test]
    [TestCase(1,2,3)]
    [TestCase(1,2)]
    [TestCase(2,1,3)]
    [TestCase(2,1)]
    [TestCase(3,2)]
    public void Test_Should_Fail_If_GetMessages_Does_Not_Return_Sorted_By_Sent_Then_By_Id_Result(params int[] ordering)
    {
        var questions = GetQuestionsData();                     
        Mock.Get(_questionService)
            .Setup(o => o.GetQuestions())
            .Returns(questions);
        var result = _mailboxService.GetMessages();    
        var expectedOrder = ordering.Select(x => result.First(o => o.Id == x));

        // Act
        Action sortOrder = () => expectedOrder.Should()
            .BeInDescendingOrder(o => o.Sent)
            .And.BeInDescendingOrder(o => o.Id);

        // Assert
        sortOrder.ShouldThrow<AssertionException>();
    }
