c＃生成的csv文件通过嵌入到电子邮件底部的电子邮件在莲花注释中发送

问题描述

我有这个weired问题，通过电子邮件使用.NET SmtpClient发送的CSV附件出现在电子邮件的底部，而不是Lotus Notes中的附件。我只是不知道如何计算出来，我没有访问客户端电脑使调试非常困难。

I am having this weired issue that CSV attachment sent via email using .NET SmtpClient appeared at the bottom of the email rather than attachment in Lotus Note. I just don’t know how to figure it out and I have no access to client computer makes debugging very hard. What are the possible steps I can take and possible gotchas I need to be aware of?

代码如下：

var smtpClient = new SmtpClient
{
   Host = ConfigurationManager.AppSettings["smtpServer"],
   Port = Convert.ToInt32(ConfigurationManager.AppSettings["smtpPort"])
};
var mailMessage = new MailMessage();
mailMessage.Attachments.Add(new Attachment(attachment, contentType)); 

//ContentType = "text/csv";
//attachment is the temp file disk path

$ b

推荐答案

这是一个有点可及，但你可能想设置附件的内容处置。

This is a bit of a reach, but you may want to set the content-disposition of the attachment.

var mailMessage = new MailMessage();
Attachment data = new Attachment(attachment, contentType); 
ContentDisposition disposition = data.ContentDisposition;
disposition.FileName = "message.csv";
mailMessage.Attachments.Add(data);
