.NET中使用Exchange 2007 Webservice来读取邮件 收藏
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.

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";
30            message.Body = new BodyType();

36            message.Sender.Item.EmailAddress = mailFrom;
37            message.ToRecipients = new EmailAddressType[1];
38            message.ToRecipients[0] = new EmailAddressType();
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                }
56                else
57                {
58                    Console.WriteLine("Item was created");
59                    Console.ReadLine();
60                }
61            }
62            catch (Exception e)
63            {
64                Console.WriteLine(e.Message);
65                Console.ReadLine();
66            }
67        }
