C# 通过首先在列表中查找要排序的字段对列表进行排序

这一个似乎很难，并将感谢任何帮助或协助，一个人可能能够给予

我有一张单子，单子。每个汽车对象都有一个列表，列表。我想按这些附件中的一个对我的汽车清单进行分类。在我的例子中，我保证有几个汽车物体和我试图找到的附件

现在我知道了附件名称，但我不知道在附件名称上对汽车列表进行排序时使用的语法

• AccessoryObj1=>名称（字符串：动态转向）
• AccessoryObj2=>名称（字符串：侧辅助）

• Car1->列表（附件OBJ1、附件OBJ2、附件OBJ3）

• Car2->列表（附件OBJ1、附件OBJ2、， 附件OBJ3）

清单（Car1、Car2）

我尝试的语法如下所示：

String sortField = "Side Assist";
List<Car> sortedList = sortedList.OrderBy(
                        x => x.Accessories.OfType<Accessory>().ToList().First(y => y.Name == sortField)).ToList();

String sortField=“侧面辅助”；
List sortedList=sortedList.OrderBy(
x=>x.Accessories.OfType（）.ToList（）.First（y=>y.Name==sortField））.ToList（）；

我试图通过引用每个汽车对象的附件列表，并在附件列表中附件对象的名称与sortField值匹配的情况下进行第一次匹配，从而对我的汽车列表进行排序（升序）

不幸的是，此尝试会导致以下错误：

必须至少有一个对象实现IComparable

我希望我的问题足够清楚，并提前表示感谢

感谢用户2399170提供的解决方案，我已经完成了3/4的步骤：获取他们的解决方案/示例，我现在尝试将最终结果按升序/降序排列。以下是调整后的代码：

public class Accessory

    public string Name { get; set; }
    public string Value { get; set; }
}

public class Car

        List<Car> sortedCars = sortRules
            .SelectMany(sortRule => cars.Where(car => car.Accessories.Any(acc => acc.Name == sortRule)))
            .Distinct().ToList();

        return sortedCars;
    }

我想根据排序字段'Name'的值对最终结果进行排序，在本例中，该字段为“奥迪”、“宝马”、“马自达”

这一切的工作原理是，用户可以从下拉列表“Name”中选择，结果可以按“Name”的值排序。不幸的是，这是我无法控制的第三方源返回数据的方式。

要按

附件进行排序

您需要确保类实现

IComparable

接口

public class Accessory : IComparible
{
    public int CompareTo(object obj) {
        //Return 0 for equals
        //Return -1 if this object precedes the given object
        //Return 1 if this object follows the given object
    }
}

试试这个样品

private static IEnumerable<Car> GetCars(string filterByAccessory, bool sortAscending = true)
{
    var cars = new List<Car>();
    cars.Add(
        new Car()

            new Accessory() { Name = "Airbag", Value = "1" },
            new Accessory() { Name = "Climate Control", Value = "1" },
            new Accessory() { Name = "Heated Seats", Value = "1" },

            new Accessory() { Name = "Name", Value = "BMW" },
        }
