設置電子郵件附件名稱

Question

我添加附件像這樣：

System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(AttachmentPath); 
msg.Attachments.Add(attachment); 

但我想讓它附加爲不同的名字，實際的文件名很長，混亂我想它連接作爲「file.txt」，是否有一個簡單的方法來做到這一點，而不必複製文件？

Answer 1

如何：

System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(attachmentPath); 
attachment.Name = "file.txt"; // set name here 
msg.Attachments.Add(attachment); 

Answer 2

您需要加載從流的連接，然後你可以給它一個名字和一個媒體類型。

var fs = new FileStream("attachmentPath", FileMode.Open); 
var attachment = new System.Net.Mail.Attachment(fs, "MyAttachmentName.txt", "text/text");
