如何对列表<string>/字符串版本号数组进行排序?

How to sort a list<string> / array of string version number?

我有一个版本字符串列表(见图),我想按降序对它们进行排序。

我见过一些使用版本 class 来比较它们的解决方案,但我想不出有任何解决方案可以像这样对整个列表进行排序。实现这一目标最简单的方法是什么?

这个简单的实现有什么问题?

using System;
using System.Collections.Generic;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var ver = new List<Version>();

            ver.Add(new Version("3.5"));
            ver.Add(new Version("3.15"));
            ver.Add(new Version("3.10"));
            ver.Add(new Version("3.1"));

            ver.Sort();
            ver.Reverse();
        }
    }
}

你可以使用 IComparable

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
              List<string> data = new List<string>{
                "3.5.0.1", "3.4.1.9", "3.4.1.56", "3.4.1.55", "3.4.1.46",
                "3.4.1.45", "3.4.1.44", "3.4.1.30", "3.4.1.3", "3.4.1.22",
                "3.4.1.2", "3.4.1.11", "3.4.1.0", "3.4.0.7", "3.4.0.3",
                "3.4.0.1", "3.3.0.8", "3.3.0.4", "3.3.0.0", "3.2.0.9",
                "3.2.0.6", "3.2.0.3", "3.2.0.27", "3.2.0.20", "3.2.0.15",
                "3.2.0.1", "3.2.0.0", "3.1.0.7", "3.1.0.15", "3.1.0.14"
              };
              List<SortPara> sortPara = data.Select(x => new SortPara(x)).ToList();
              data = sortPara.OrderBy(x => x).Select(x => x.strNumbers).ToList();
              data = sortPara.OrderByDescending(x => x).Select(x => x.strNumbers).ToList();
        }

    }
    public class SortPara : IComparable<SortPara>
    {
        public List<int> numbers { get; set; }
        public string strNumbers { get; set; }
        public SortPara(string strNumbers)
        {
            this.strNumbers = strNumbers;
            numbers = strNumbers.Split(new char[] { '.' }).Select(x => int.Parse(x)).ToList();

        }
        public int CompareTo(SortPara other)
        {
            int shortest = this.numbers.Count < other.numbers.Count ? this.numbers.Count : other.numbers.Count;
            int results = 0;
            for (int i = 0; i < shortest; i++)
            {
                if (this.numbers[i] != other.numbers[i])
                {
                    results = this.numbers[i].CompareTo(other.numbers[i]);
                    break;
                }
            }
            return results;
        }
    }
}

您应该使用 IComparable 作为 jdweng,只需编辑一下以比较“2.1.0.4”和“2.1”等版本:

public int CompareTo(SortPara other)
    {
        int shortest = this.numbers.Count < other.numbers.Count ? this.numbers.Count : other.numbers.Count;
        int results = 0;
        for (int i = 0; i < shortest; i++)
        {
            if (this.numbers[i] != other.numbers[i])
            {
                results = this.numbers[i].CompareTo(other.numbers[i]);
                break;
            }
        }
        if (results != 0)
            return results;
        if (this.numbers.Count > other.numbers.Count)
            return 1;
        else if (this.numbers.Count < other.numbers.Count)
            return -1;
        else
            return 0;
    }

这里有一个解决方案,可以对语义版本控制 (https://semver.org) 进行排序。 Nuget.Core 提供了一个 SemanticVersion class,其操作与 .net 中的标准版本 class 非常相似。它会将您的字符串解析为 IComparable 和 IEquatable 对象,以便您可以比较多个版本或在集合中对它们进行排序等。

Nuget.Core: https://www.nuget.org/packages/nuget.core/(你可以通过 nuget 拉取这个库)

https://github.com/NuGet/NuGet2/blob/2.13/src/Core/SemanticVersion.cs

var rawVersions = new [] {"v1.4.0", "v1.4.0-patch10", "v1.4.0-patch2"};
var versions = rawVersions.Select(v => new SemanticVersion(v));
var sorted = versions.ToList().Sort();

知道这是一个旧话题,但最简单的方法是:

//list with some version numbers as strings
var versionList = new List<string>()
{
   "1.1.0",
   "1.10.0",
   "1.112.0",
}     
versionList.OrderByDescending(x => Version.Parse(x));

输出:
1.112.0
1.10.0
1.1.0
