Set Email Attachment name in C#
问题 I add an attachment like this: System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(AttachmentPath); msg.Attachments.Add(attachment); But I want to make it attach as a different name, the actual file name is very long and confusing I would like it to attach as "file.txt", is there an easy way to do this without having to make a copy of the file? 回答1: How about: System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(attachmentPath); attachment.Name = "file.txt
