如何在C#中获取SharePoint库中每个文件夹中的每个项目？

using Microsoft.SharePoint.Client;
using System;

class Program
{
    static void Main(string[] args)
    {
        string siteUrl = "https://your-sharepoint-site-url";
        string libraryName = "Documents";

        using (ClientContext context = new ClientContext(siteUrl))
        {
            // 身份验证
            context.AuthenticationMode = ClientAuthenticationMode.Default;
            context.Credentials = new SharePointOnlineCredentials("username", "password");

            // 获取文档库
            List library = context.Web.Lists.GetByTitle(libraryName);
            context.Load(library);
            context.ExecuteQuery();

            // 获取文档库中的所有文件夹
            CamlQuery query = new CamlQuery();
            query.ViewXml = "<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='FSObjType' /><Value Type='Integer'>1</Value></Eq></Where></Query></View>";
            ListItemCollection folders = library.GetItems(query);
            context.Load(folders);
            context.ExecuteQuery();

            // 遍历每个文件夹并获取其中的项目
            foreach (ListItem folder in folders)
            {
                context.Load(folder);
                context.ExecuteQuery();

                Console.WriteLine("文件夹名称: " + folder["FileLeafRef"]);

                // 获取文件夹中的所有项目
                FolderItem folderItem = folder.Folder;
                context.Load(folderItem);
                context.ExecuteQuery();

                FileCollection files = folderItem.Files;
                context.Load(files);
                context.ExecuteQuery();

                foreach (File file in files)
                {
                    context.Load(file);
                    context.ExecuteQuery();

                    Console.WriteLine("项目名称: " + file.Name);
                    Console.WriteLine("项目路径: " + file.ServerRelativeUrl);
                }
            }
        }

        Console.ReadLine();
    }
}
