System.Web.Mail.MailAttachment problems with sending a message with attachment file
-
Hello everyone! I know that System.Web is obsolete, but I can't use System.Net. becouse MS update for System.Net does't work for me. So I have to use System.Web.Mail.MailMessage instead. It works fine. But when I try to attach file with
mailMessage.Attachments.Add(new System.Web.Mail.MailAttachment(Settings.Default.LicenseFilesStore + licenseFilePath));My e-mail simply could't be delivered Could someone please provide me with an advice. M.b. suggestion to download & use some custom developed smtp class. Thanks in advance. -

Was there any return message?? Some kind of error message?? Anything on the recipients end at all??

I don't know why MS update for System.Net does't work for me. So I use System.Web

Return message - "protocol is unknown" Exception data - "System.Collections.ListDictionaryInternal" Nothing on the recipients with attached file. But works well without attachment. Thanks for help

I've refused using System.Web namespace becouse I've solved the problem with System.Net The problem was pretty stupid. I've downloaded update for Framework 2.0 link[^] and installed it to ALL CUSTOMERS' PCs.
