If the file is attached as an embedded file, go to the attachments tab where the list of attached files is displayed, right-click (Mac: Ctrl+Click) on the attached file and choose the option Delete.
Open your phone's Files app . Tap a file. Delete .
Tap on the contact icon and select Info. Scroll down to see the attachments the contact has sent you. Tap See All and select the ones you want to delete. When you are done, tap Delete.
Dispose of the MailMessage when you're done with it. It still has a lock on the file you've added as an attachment until you've done so.
var filePath = "C:\\path\\to\\file.txt";
var smtpClient = new SmtpClient("mailhost");
using (var message = new MailMessage())
{
message.To.Add("[email protected]");
message.From = new MailAddress("[email protected]");
message.Subject = "Test";
message.SubjectEncoding = Encoding.UTF8;
message.Body = "Test " + DateTime.Now;
message.Attachments.Add(new Attachment(filePath));
}
if (File.Exists(filePath)) File.Delete(filePath);
Console.WriteLine(File.Exists(filePath));
Output: False
I would imagine that if you still have something locking the file after disposing the message, that you likely have another lock on the file, but without code, we can't help you.
