sharepoint 发送邮件 带附件
【转http://www.cnblogs.com/McJeremy/archive/2009/07/02/1515441.html】
也许我们习惯用通过使用System.Net.Mail中的相关类进行邮件的发送。
这其中,需要我们手动指定邮件服务器、发件人地址进行邮件的发送。
而在SharePoint中,这些东西都可以通过应用程序》传出电子邮件来进行设置。那么,如果我们要将.Net.Mail与SharePoint结合起来,该怎么做呢?
关键就在于,如何通过SP的对象模型获取到设置的服务器、地址等数据,下面是我一些小的总结,希望能对大家有所帮助:
//第一步:获取应用程序,因为 传出电子邮件设置是在应用程序中进行的 site.WebApplication
Microsoft.SharePoint.Administration.SPWebApplication webApp = site.WebApplication;
//第二步:获取邮件服务器主机名 webApp.OutboundMailServiceInstance.Server.Name
client.Host = webApp.OutboundMailServiceInstance.Server.Name;
//第三步:获取发送人地址:webApp.OutboundMailSenderAddress;
//第四步:获取邮件编码 :
message.BodyEncoding = System.Text.Encoding.GetEncoding(webApp.OutboundMailCodePage);
----在我目前的工作中,碰到这样一个场景:在某个列表中添加一项列表项后,自动获取列表中的“收件人”和“发件人”字段进行邮件发送。
因此,我写了如下的测试代码,
该测试代码实现:
1、选择列表项字段“收件人”作为邮件收件人,选择列表项字段“抄送发”作为邮件抄送人,值得一提的是,在SP中,这2个被设置成“用户或用户组”后,还可以选择组进行发送目标,这一个非常爽。
2、自动将列表项的附件作为邮件附件发送。
特别注意的是,虽然我此处是写的一个列表事件处理程序,但是,邮件的发送方法以及传出电子邮件设置的获取是通过型的。
运行通过的代码:
