如何使用LINQ从每个集合中获取最大版本的记录？

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

public class Record
{
    public string CollectionName { get; set; }
    public int Version { get; set; }
    // 其他属性...
}

public class Program
{
    public static void Main()
    {
        List<Record> records = new List<Record>
        {
            new Record { CollectionName = "Collection1", Version = 1 },
            new Record { CollectionName = "Collection1", Version = 3 },
            new Record { CollectionName = "Collection2", Version = 2 },
            new Record { CollectionName = "Collection2", Version = 5 },
            new Record { CollectionName = "Collection3", Version = 4 }
        };

        var maxVersionRecords = records
            .GroupBy(r => r.CollectionName)
            .Select(g => g.OrderByDescending(r => r.Version).First())
            .ToList();

        foreach (var record in maxVersionRecords)
        {
            Console.WriteLine($"Collection: {record.CollectionName}, Max Version: {record.Version}");
        }
    }
}
