如何将Outlook电子邮件搜索结果存储到IEnumerable对象(C#)中

using Microsoft.Graph;
using System.Collections.Generic;
using System.Linq;

// 创建Microsoft Graph客户端实例
GraphServiceClient graphClient = new GraphServiceClient(authProvider);

// 执行Outlook电子邮件搜索
var searchResults = await graphClient.Me.MailFolders.Inbox.Messages
    .Request()
    .Filter("subject:searchKeyword") // 替换为实际的搜索关键字
    .Select("subject,from,receivedDateTime") // 可选，指定要返回的邮件属性
    .GetAsync();

// 将搜索结果存储到IEnumerable对象中
IEnumerable<Message> emailResults = searchResults.CurrentPage;

// 示例：筛选出发送时间在过去一周内的邮件
DateTime oneWeekAgo = DateTime.Now.AddDays(-7);
IEnumerable<Message> filteredResults = emailResults
    .Where(email => email.ReceivedDateTime >= oneWeekAgo);
