请给我一段C#代码，需求是使用exchange接收163邮箱的邮件

以下是使用 Microsoft Exchange Server Web Services (EWS) 来收取 163 邮箱的邮件的 C# 代码示例：

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

namespace ReceiveEmail
{
    class Program
    {
        static void Main(string[] args)
        {
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

            ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
            service.Credentials = new WebCredentials("YourEmailAddress@163.com", "YourPassword");
            service.AutodiscoverUrl("YourEmailAddress@163.com");

            FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
            foreach (Item item in findResults.Items)
            {
                Console.WriteLine(item.Subject);
                Console.WriteLine(item.DateTimeReceived);
                Console.WriteLine(item.Body.Text);
            }

            Console.ReadLine();
        }
    }
}

请注意，您需要将 "YourEmailAddress@163.com" 和 "YourPassword" 替换为您自己的 163 邮箱地址和密码。另外，您需要安装 Microsoft Exchange Server Web Services Managed API 来运行此代码示例。
