File name ABC.pdf is invalid – error while creating attachment programmatically
The other day I was getting “Invalid file name” error when I try to create an attachment with .pdf file and associating to Email, in my plug-in. (link)
Reason
- Reason was “pdf” was added as blocked file extension for attachments in my CRM organization.
Fix :-
- Go to “Settings -> Administration -> System Settings”
- Remove pdf from “Blocked file extension for attachment”
Blocked file extensions
- Click ‘OK’

Adding file as “Attachment” to activities programmatically in plug-in
Hi,
We can add file as attachment and associate to the CRM objects i.e., Email, Task etc…
Email with .pdf file as attachment
The entity that store attachment information is “activitymimeattachment”
Below is the code snippet to add “.pdf” file as attachment to the Email activity
Entity attachment = new Entity(“activitymimeattachment”);
attachment[“subject”] = “My Subject”;
string fileName = “Sample.pdf”;
attachment[“filename”] = fileName;
byte[] fileStream= = new byte[] { }; //Set file stream bytes
attachment[“body”] = Convert.ToBase64String(fileStream);
attachment[“mimetype”] = “text/plain”;
attachment[“attachmentnumber”] = 1;
Guid emailId; //GUID of Email activity
attachment[“objectid”] = new EntityReference(“email”, emailId);
attachment[“objecttypecode”] = “email”;
IOrganizationService service;
service.Create(attachment);
Note :-
- In the above code the property “objecttypecode” is slight misleading, as it expects “EntityLogicalName” rather than “EntityTypeCode”
- So make sure to set attachment[“objecttypecode”] = EntityLogicalName (i.e., email)
