我如何声明不同大​​小的3d数组

Question

我试图实现这样的目标：

这意味着什么？很快，首先我有一些数据（例如祖父），每个人都有不同数量的儿子，每个儿子都有1个儿子。

我考虑使用3D数组，但是第二个数组的不同数量将无法使用此方法。那我怎么能实现呢？

Answer 1

您可以使用此功能，例如：

List< List < Element > >

Answer 2

        var multiDimesionalList = new List<List<string>>
        {
            new List<string> { "List one, Child One", "List one, Child Two", "List one, Child Three" },
            new List<string> { "List two, Child One", "List two, Child Two", "List two, Child Three" }
        };

您可以根据需要创建一个列表深度，以创建所需的层次结构。

这是一种方法：

将在示例中使用的测试类：

using System;
using Microsoft.Exchange.WebServices.Data;
using System.Net;
using System.IO;
using System.Diagnostics;

namespace EWS_API
{
    class Program
    {
        static void Main(string[] args)
        {
            ExchangeService service = new ExchangeService(ExchangeVersion.Exchange010_SP);

            service.Credentials = new NetworkCredential("user", "pwd", "domain");

            service.TraceEnabled = true;
            service.TraceFlags = TraceFlags.All;

            // ignore certificate errors
            ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, errors) => true;

            // set ews uri without autodiscover (just for internal use)
            service.Url = new Uri("https://fqdn_server/EWS/exchange.asmx");

            // filter for only daily mails
            SearchFilter searchFilter = new SearchFilter.IsGreaterThan(ItemSchema.DateTimeReceived, DateTime.Now.AddDays(-1));

            ItemView itemView = new ItemView(int.MaxValue);
            FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, searchFilter, itemView);

            if (findResults != null && findResults.Items != null && findResults.Items.Count > 0)
                foreach (Item item in findResults.Items)
                {
                    EmailMessage message = EmailMessage.Bind(service, item.Id, new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments, ItemSchema.HasAttachments));
                    foreach (Attachment attachment in message.Attachments)
                    {
                        if (attachment is FileAttachment)
                        {
                            FileAttachment fileAttachment = attachment as FileAttachment;
                            fileAttachment.Load();
                            fileAttachment.Load("C:\\temp\\" + fileAttachment.Name);
                        }
                    }
                    Debug.WriteLine(item.Subject);
                }
            else
                Debug.WriteLine("no items");
        }
    }
}

..它在无尽级别列表中的用法

public class MyClassOfSomeData
{
    public int ID { get; set; }
    public string Name { get; set; }
    //etc...
    public List<MyClassOfSomeData> Children = new List<MyClassOfSomeData>();
}
