我有一个字节数组,基本上是从数据库中检索到的编码为.docx的文件。我尝试将这个字节数组转换回它的原始文件,并将其作为附件添加到邮件中,而不必先将其存储为磁盘文件。
最好的方法是什么?
public MailMessage ComposeMail(string mailFrom, string mailTo, string copyTo, byte[] docFile)
{
var mail = new MailMessage();
mail.From = new MailAddress(mailFrom);
mail.To.Add(new MailAddress(mailTo));
mail.Body = "mail with attachment";
System.Net.Mail.Attachment attachment;
//Attach the byte array as .docx file without having to store it first as a file on disk?
attachment = new System.Net.Mail.Attachment("docFile");
mail.Attachments.Add(attachment);
return mail;
}
