LINQ with subselect和groupby只获取列表中每个项目的最新版本

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

class Project
{
    public string Name { get; set; }
    public int Version { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        // 创建一个包含项目列表的List<Project>
        List<Project> projects = new List<Project>
        {
            new Project { Name = "Project1", Version = 1 },
            new Project { Name = "Project1", Version = 2 },
            new Project { Name = "Project2", Version = 1 },
            new Project { Name = "Project2", Version = 2 },
            new Project { Name = "Project3", Version = 1 },
        };

        // 使用LINQ查询获取每个项目的最新版本
        var latestProjects = projects
            .GroupBy(p => p.Name)
            .Select(g => new Project
            {
                Name = g.Key,
                Version = g.Max(p => p.Version)
            })
            .ToList();

        // 输出结果
        foreach (var project in latestProjects)
        {
            Console.WriteLine($"{project.Name} - Version {project.Version}");
        }
    }
}

Project1 - Version 2
Project2 - Version 2
Project3 - Version 1
