MailMessage objMailMessage = new MailMessage();
objMailMessage.From = new MailAddress(from, senderName);
objMailMessage.To.Add(new MailAddress(to));
objMailMessage.Subject = addSub + " " + (string)mailParameters[1];

objMailMessage.IsBodyHtml = isHTML; 
objMailMessage.Attachments.Add(new Attachment("my file 1 path"));
objMailMessage.Attachments.Add(new Attachment("my file 1 path"));

Answer 1

您似乎要将相同的文件附加两次（＆＃34;我的文件1路径＆＃34;）。附加两个或多个不同的文件
