Pranav Kulkarni's Blog: Email with Embedded (Inline) image in sharepoint

Wednesday, September 10, 2014

In asp.net we can send an email with inline image as explained in this post
http://stackoverflow.com/questions/18358534/send-inline-image-in-email

But in sharepoint the procedure is slightly different. I have used below post to do the stuff

http://sharepoint-tamizha.blogspot.co.uk/2013/08/send-email-with-embedded-images-in-c.html

And the final code looks like

byte[] imgByte = null;

SPFile file = SPContext.Current.Web.GetFile(ImageUrl);

imgByte = file.OpenBinary();

// Creating Unique ID for adding image referrence

string GUId1 = Guid.NewGuid().ToString();

// frame the HTML with the img tag and above unique id

string htmlBody = "<html><body><div><img src=\"cid:" + GUId1 + "\"></div></body></html>";

// Create alternateview object with Mime type HTML

AlternateView avHtml = AlternateView.CreateAlternateViewFromString

(htmlBody, null, MediaTypeNames.Text.Html);

//Create object for Linked Resource with the Image physical path or Image Stream

MemoryStream stream = new MemoryStream(imgByte);

LinkedResource pic1 = new LinkedResource(stream, "image/png");

// Provide the previously created Unique ID to associate the Image with the respective img src.

pic1.ContentId = GUId1;

//Add the Linked Resource to the AlternateView

avHtml.LinkedResources.Add(pic1);

string from = SPContext.Current.Web.Site.WebApplication.OutboundMailSenderAddress;

string smtpAddress =SPContext.Current.Web.Site.WebApplication.OutboundMailServiceInstance.Server.Address;

// Assign SMTP address

SmtpClient smtpClient = new SmtpClient();

smtpClient.Host = smtpAddress;

MailMessage mailMessage = new MailMessage(from, toRecipients);

mailMessage.Subject = subject;

// Add the Alternate view with the Mail message

mailMessage.AlternateViews.Add(avHtml);

mailMessage.IsBodyHtml = true;

smtpClient.Send(mailMessage);
