最近项目中需要用到exchange的操作,就参照msdn弄了一个简单的操作类。目前先实现了,发送邮件和拉取收件箱的功能,其他的以后在慢慢的添加。
using Microsoft.Exchange.WebServices.Data; using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Text; using System.Threading.Tasks; namespace WebSite.Utilities.Mail { /// <summary> /// exchange邮件客户端类 /// </summary> public class ExChangeMailClient { /// <summary> /// exchange服务对象 /// </summary> private static ExchangeService _exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP1); /// <summary> /// 获取收件箱 /// </summary> /// <param name="userId">当前用户名</param> /// <param name="pwd">密码</param> /// <param name="domain">域</param> /// <param name="pageSize">一次加载的数量</param> /// <param name="offset">偏移量</param> /// <returns></returns> public static List<Email> GetInbox(string userId, string pwd, string domain, int pageSize, int offset) { try { if (string.IsNullOrEmpty(userId) || string.IsNullOrEmpty(pwd) || string.IsNullOrEmpty(domain)) { throw new ArgumentNullException("当前用户信息为空,无法访问exchange服务器"); } List<Email> lstEmails = new List<Email>(); _exchangeService.Credentials = new NetworkCredential(userId, pwd, domain); _exchangeService.Url = new Uri(WebConfig.ExchangeServerUrl); ItemView view = new ItemView(pageSize, offset); FindItemsResults<Item> findResults = _exchangeService.FindItems(WellKnownFolderName.Inbox, SetFilter(), view); foreach (Item item in findResults.Items) { item.Load(PropertySet.FirstClassProperties);
//转化为EmailMessage获取 获取邮件详情
var currentEmail = (Microsoft.Exchange.WebServices.Data.EmailMessage)(item);
List<string> ccRecipientsEmailLists = new List<string>();
List<string> bccRecipientsEmailLists = new List<string>();
foreach (var cc in currentEmail.CcRecipients)
{
ccRecipientsEmailLists.Add(cc.Address);
}
foreach (var bcc in currentEmail.BccRecipients)
{
bccRecipientsEmailLists.Add(bcc.Address);
}
lstEmails.Add(new Email()
{
ExchangeItemId = item.Id.ChangeKey,
body = item.Body.Text,

Mail_bcc = string.Join(";", bccRecipientsEmailLists.ToArray()),
