很久没有更新过博客了，这几个月比较忙，人也比较懒散，今天已经是八月份，新的一个月希望要换一个状态。今天要写的文章是我四月份写的一个功能，一直拖到现在才发表。在企业内部我们一般都是使用微软的Exchange服务器来进行邮件的存储及发送，我们一般在客户端用outlook来收发邮件。工作中遇到了一个需求，需要写一个程序来抓取邮件服务器的邮件，并将抓取下来的邮件存储到数据库中。之前已经发表过一篇文章，是利用Jmail组件来抓取，可以抓取我们常用的一些邮箱的邮件，比如说163，gmail等，但是不能抓取exchange服务器中的邮件，所以需要重新写，最后决定使用Exchange 2007 中提供的webservice来抓取邮件。网络上这方面的资料很少，所以大部分的参考是来自MSDN：
http://msdn.microsoft.com/en-us/library/exchangewebservices(EXCHG.80).aspx
2007版的Exchange服务器提供了webservice，我们可以方便的在.NET程序中添加该引用，然后就可以方便的实现邮件的抓取，发送，删除等功能。我测试是在控制台程序中使用该webservice，步骤如下：
1 新建一个站点，然后添加exchange webservice 的引用，输入邮件服务器的OWA地址：http://yourmailserver/EWS/Services.wsdl,如果是在公司的内部域中，添加的过程中要求输入你的域帐号和密码。
2 添加成功以后再项目中导入该命名空间以其他必须的命名空间;
3 下面就是具体的代码，具体的请看注释：
发送邮件：
1 public static void CreateEmail(string userName, string passWord, string domain, string url, string mailFrom, string mailTo)
2 {
3 // Create service binding.
4 // 建立service绑定
5 ExchangeServiceBinding esb = new ExchangeServiceBinding();
6 esb.Credentials = new NetworkCredential(userName, passWord, domain);
7 esb.Url = url;
8
9 // Create the CreateItem request.
10 CreateItemType createItemRequest = new CreateItemType();
11
12 // Specifiy how the created items are handled
13 // 如何处理邮件
14 createItemRequest.MessageDisposition = MessageDispositionType.SendAndSaveCopy;
15 createItemRequest.MessageDispositionSpecified = true;
16
17 // Specify the location of sent items.
18 createItemRequest.SavedItemFolderId = new TargetFolderIdType();
19 DistinguishedFolderIdType sentitems = new DistinguishedFolderIdType();
20 sentitems.Id = DistinguishedFolderIdNameType.sentitems;
21 createItemRequest.SavedItemFolderId.Item = sentitems;
22
23 // Create the array of items.
24 createItemRequest.Items = new NonEmptyArrayOfAllItemsType();
25
26 // Create a single e-mail message.
27 // 新建一封邮件message对象
28 MessageType message = new MessageType();
29 message.Subject = "Tommy Test";

39 message.ToRecipients[0].EmailAddress = mailTo;
40 message.Sensitivity = SensitivityChoicesType.Normal;
41
42 // Add the message to the array of items to be created.
43 createItemRequest.Items.Items = new ItemType[1];
44 createItemRequest.Items.Items[0] = message;
45
46 try
47 {
48 // Send the request to create and send the e-mail item, and get the response.
49 CreateItemResponseType createItemResponse = esb.CreateItem(createItemRequest);
50
51 // Determine whether the request was a success.
52 if (createItemResponse.ResponseMessages.Items[0].ResponseClass == ResponseClassType.Error)
53 {
54 throw new Exception(createItemResponse.ResponseMessages.Items[0].MessageText);
55 }
