如何通过LINQ选择队列中最常出现的值？

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

class Program
{
    static void Main()
    {
        Queue<int> myQueue = new Queue<int>();
        myQueue.Enqueue(1);
        myQueue.Enqueue(2);
        myQueue.Enqueue(3);
        myQueue.Enqueue(2);
        myQueue.Enqueue(1);
        myQueue.Enqueue(2);

        int mostFrequent = FindMostFrequent(myQueue);
        Console.WriteLine("Most frequent value: " + mostFrequent);
    }

    static int FindMostFrequent(Queue<int> queue)
    {
        var itemCounts = queue.GroupBy(item => item)
                              .Select(group => new { Value = group.Key, Count = group.Count() });
        int maxCount = itemCounts.Max(ic => ic.Count);
        return itemCounts.First(ic => ic.Count == maxCount).Value;
    }
}
