按参考C#对列表进行排序 [英] Sort a list by reference C#

问题描述

我有一个List<Unit>，其中Unit包含Name和Value.在此对象中，我存储有关服装尺码的信息，Name包含尺码名称(S，M，L，XL ..)，Value包含该尺码的数量.

I have a List<Unit> where Unit contains Name and Value. In this object I store information about apparel sizes Name contains size names (S,M,L,XL..) and Value contains the quantity of that size.

此单元列表是从数据库中包含的，但是列表是随机排列的，因此在列表中，它可能是这样的:

This unit list is contained from a database, but the list comes in random order, so in the liste it might be like this:

Unit(M,3)
Unit(S,1)
Unit(XXL,2)
Unit(L,2)

我想对列表进行排序，使其变得更像这样:

I would like to sort the list so that it become more like this:

Unit(S,1)
Unit(M,3)
Unit(L,2)
Unit(XXLL,2)

我不能订购字符串ASCE或DESC，因为它M在S之前，依此类推. 然后我想我可以创建一个具有正确顺序(XXS，XS，S，M，L，XL，XXL，XXXL)的引用数组，但是如何根据引用对列表进行排序.

I cant order on the string ASCE or DESC since it M comes before S and so on. Then I thought I might create an reference Array with the correct order (XXS,XS,S,M,L,XL,XXL,XXXL), but how can I sort my list according to the reference.

或者还有其他聪明的方法吗?

Or are there other clever ways of doing this?

更新

感谢所有好的回答，我找到了Enum解决方案，它最终看起来像这样:

Thanks for all good answers, I landed on the Enum solution, and it finally looks like this:

public class Unit
{
    public Unit()
    {
    }

    public Unit(string name, int value)
    {
        Value = value;
        SizeCode = AssignSizeCode(name);
    }

    public SizeCode SizeCode { get; set; }
    public int Value { get; set; }

    private SizeCode AssignSizeCode(string name)
    {
        switch (name)
        {
            case "XXS":
                return SizeCode.XXS;
            case "XS":
                return SizeCode.XS;
            case "S":
                return SizeCode.S;
            case "M":
                return SizeCode.M;
            case "L":
                return SizeCode.L;
            case "XL":
                return SizeCode.XL;
            case "XXL":
                return SizeCode.XXL;
            case "XXXL":
                return SizeCode.XXXL;
            default:
                return SizeCode.Unknown;
        }
    }

}

public enum SizeCode
{
    XXS = 1,
    XS = 2,
    S = 3,
    M = 4,
    L = 5,
    XL = 6,
    XXL = 7,
    XXXL = 8,
    Unknown = 9
}

我这样排序:

units = units.OrderBy(x => (int)x.SizeCode).ToList();

有什么意见或我需要改进的地方吗?

Any comments, or things I can improve?

推荐答案

如何使用枚举

public enum Size
    {
        Small = 1,
        Medium = 2,
        // etc 

    }

然后，您可以将Unit类中的枚举值转换为int并按整数值排序.

Then you can convert the enum value in Unit class to int and sort by the integer value.
