为递送编号、总页数、页码创建的列表需要使用c#查找丢失的页码

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        int deliveryNumber = 100; // 递送编号
        int totalPages = 10; // 总页数
        List<int> pageList = new List<int>() { 1, 2, 3, 4, 6, 7, 8, 10 }; // 页码列表

        List<int> missingPages = FindMissingPages(deliveryNumber, totalPages, pageList);
        Console.WriteLine("Missing pages: " + string.Join(", ", missingPages));
    }

    public static List<int> FindMissingPages(int deliveryNumber, int totalPages, List<int> pageList)
    {
        List<int> missingPages = new List<int>();

        // 创建包含所有页码的列表
        List<int> allPages = new List<int>();
        for (int i = 1; i <= totalPages; i++)
        {
            allPages.Add(i);
        }

        // 查找丢失的页码
        foreach (int page in allPages)
        {
            if (!pageList.Contains(page))
            {
                missingPages.Add(page);
            }
        }

        return missingPages;
    }
}
