How to add attachments to an activity/email inMicrosoft Dynamics CRM using c#

Today we'll learn how we can send emails along with attachments using c# code.

There are situations when we need to generate emails using plugins or sometime we need to build

scheduler services to send emails along with attachments on regular interval.

In such scenario one needs to write code to create email activity in CRM using code and send that email from code itself.

Here is the C# code snippet to do the same:

How to create toParty:

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

   Entity toParty = new Entity("activityparty");
   toParty["participationtypemask"] = new OptionSetValue(0);
   toParty["addressused"] = "email address of receiver";
   toParty["fullname"] = "full name of receiver";

How to send email along with the attachment:

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

 public static void sendEmail(Entity to_Party,String Emailbody,String attachmentbody,IOrganizationService service)

        {

            Entity email = new Entity("email");

            Entity from_Party = new Entity("activityparty");

           

           QueryExpression queue = new QueryExpression("queue");

            queue.Criteria.AddCondition("name", ConditionOperator.Equal, "your sender queue name");

            queue.Criteria.AddCondition("statecode", ConditionOperator.Equal, 0);

            EntityCollection queueColl = service.RetrieveMultiple(queue);

            if (queueColl.Entities.Count > 0)

            {

                from_Party["partyid"] = new EntityReference("queue", queueColl.Entities[0].Id);

            }

            email["from"] = new Entity[] { from_Party };

            email["to"] = new Entity[] { to_Party };

            email["subject"] = "Subject of the Email";

            email["description"] = Emailbody;

            Guid emailguid = service.Create(email);

           //Add text attachment 

            addattachments(emailguid, service, attachmentbody);

            SendEmailRequest sendEmailreq = new SendEmailRequest

            {

                EmailId = emailguid,

                TrackingToken = "",

                IssueSend = true

            };

            SendEmailResponse sendEmailresp = (SendEmailResponse)service.Execute(sendEmailreq);  

        }

 public static void addattachments(Guid emailguid,String message,IOrganizationService service)

{

Entity attachment = new Entity("activitymimeattachment");

attachment["subject"] = "Attachment";

string fileName = "Attachment.txt";

attachment["filename"] = fileName;

byte[] fileStream = Encoding.ASCII.GetBytes(message);   

attachment["body"] = Convert.ToBase64String(fileStream);

attachment["mimetype"] = "text/plain";

attachment["attachmentnumber"] = 1;

attachment["objectid"] = new EntityReference("email", emailguid);

attachment["objecttypecode"] = "email";

service.Create(attachment);

}
