访问共享邮箱中收件箱中子文件夹的详细信息

要访问共享邮箱中收件箱中的子文件夹，可以使用Microsoft Graph API来实现。下面是一个使用C#代码示例的解决方法：

using Microsoft.Graph;
using Microsoft.Identity.Client;
using System;
using System.Threading.Tasks;

public class Program
{
    private static string clientId = "Your_Client_Id";
    private static string clientSecret = "Your_Client_Secret";
    private static string tenantId = "Your_Tenant_Id";
    private static string sharedMailboxEmail = "Shared_Mailbox_Email";
    private static string folderId = "Folder_Id";

    public static async Task Main(string[] args)
    {
        IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
            .Create(clientId)
            .WithClientSecret(clientSecret)
            .WithAuthority($"https://login.microsoftonline.com/{tenantId}")
            .Build();

        string[] scopes = new string[] { "https://graph.microsoft.com/.default" };

        AuthenticationResult authenticationResult = await confidentialClientApplication.AcquireTokenForClient(scopes).ExecuteAsync();
        string accessToken = authenticationResult.AccessToken;

        GraphServiceClient graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
        {
            requestMessage.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
            return Task.FromResult(0);
        }));

        try
        {
            var folder = await graphClient.Users[sharedMailboxEmail].MailFolders[folderId].Request().GetAsync();
            Console.WriteLine("Folder Name: " + folder.DisplayName);
            Console.WriteLine("Folder ID: " + folder.Id);
            Console.WriteLine("Total messages: " + folder.TotalItemCount);

            var messages = await graphClient.Users[sharedMailboxEmail].MailFolders[folderId].Messages.Request().GetAsync();
            foreach (var message in messages)
            {
                Console.WriteLine("Message ID: " + message.Id);
                Console.WriteLine("Subject: " + message.Subject);
                Console.WriteLine("Received DateTime: " + message.ReceivedDateTime.ToString());
                Console.WriteLine("Sender: " + message.Sender.EmailAddress.Name);
                Console.WriteLine();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}

请注意，你需要将代码中的以下信息替换为你自己的值：

• Your_Client_Id：你的应用程序的客户端ID
• Your_Client_Secret：你的应用程序的客户端密钥
• Your_Tenant_Id：你的租户ID
• Shared_Mailbox_Email：共享邮箱的邮箱地址
• Folder_Id：收件箱中子文件夹的ID

此示例使用了Microsoft.Identity.Client和Microsoft.Graph NuGet包。确保在项目中安装了这些包，并在代码中添加相应的using语句。此外，还需要有对共享邮箱的适当访问权限。
