从C#发送带有附件的电子邮件，附件在雷鸟中作为第1.2部分到达
提问于 2010-05-13 18:16:11
我有一个C#应用程序，它通过电子邮件发送Excel电子表格报告通过Exchange2007服务器使用SMTP。这些附件对于Outlook用户来说很好，但对于Thunderbird和Blackberry用户来说，附件已经被重新命名为"Part 1.2“。
我找到了这个article，它描述了这个问题，但似乎没有给我一个解决办法。我无法控制Exchange服务器，因此无法在那里进行更改。在C#端有什么我能做的吗？我尝试过对正文使用短文件名和HTML编码，但这两种方法都没有用。
我的邮件发送代码很简单：
public static void SendMail(string recipient, string subject, string body, string attachmentFilename)
{
SmtpClient smtpClient = new SmtpClient();
NetworkCredential basicCredential = new NetworkCredential(MailConst.Username, MailConst.Password);
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress(MailConst.Username);
// setup up the host, increase the timeout to 5 minutes
smtpClient.Host = MailConst.SmtpServer;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = basicCredential;
smtpClient.Timeout = (60 * 5 * 1000);
message.From = fromAddress;
message.Subject = subject;
message.IsBodyHtml = false;
message.Body = body;
message.To.Add(recipient);
if (attachmentFilename != null)
message.Attachments.Add(new Attachment(attachmentFilename));
smtpClient.Send(message);
}谢谢你的帮助。
