Cannot implicitly convert  SapBobsCom.attachment to System.net.mail

Hello,
as Tas said, the error happens because SAPbobsCOM.Attachemnt and System.Net.Mail.Attachemnt are different types. You can't add a SAP attachment directly to a MailMessage. System.Net.Mail.Attachment requires a file path or stream, so you need to first get the attachment from SAP to your local system or a memory stream.

Hey,

Hope you're keeping well.

SAPbobsCOM.Attachment and System.Net.Mail.Attachment are completely different types from unrelated namespaces, so you can’t pass one directly into MailMessage.Attachments. You’ll need to retrieve the file path or binary stream from the SAP object (e.g., via Attachment.Lines.SourcePath and Attachment.Lines.FileName in the DI API), then create a new System.Net.Mail.Attachment from a FileStream or MemoryStream and add that to the message. For example: using var stream = File.OpenRead(filePath); message.Attachments.Add(new System.Net.Mail.Attachment(stream, Path.GetFileName(filePath)));. Ensure the network path is accessible to the account running your code, especially if this is deployed to IIS or an Azure App Service.

Thanks and regards,

Taz
