Sending SharePoint List Item Attachments in Email Programatically.

Hi All,

Got a new thing for me, to share with you all.
when you have to send email and attachment  with it then its easy task, when attachment file is lying on your file system.
But, when Attachment is as URL format, then its a little problem , as directly ULR formats are not supported.  In this case you have to go by Steam param method for Attachment.
We need to use WebClient  class for the same. with UseDefaultCredentials property set as true.
Otherwise you will get error 401 (Un-Authorized)

Below is code snippet.  you can direcly call this method. Good to go

     public static void SendMailWithAttachment(SPWeb web, string toAddress, string ccAddress, string subject, string body,SPListItem Itemattachment)

        {

            MailMessage objEmail = new MailMessage();

            MailAddress mailFrom = null;

            SmtpClient smtp = null;

            SPWebApplication webapp = web.Site.WebApplication;

            mailFrom = new MailAddress("Admin@abc.com", "Admin");

            objEmail.From = mailFrom;

// if toAddress Contains many email addresses seperated by ','

            if (toAddress.Contains(","))

            {

                string[] tos = toAddress.Split(',');

                for (int i = 0; i < tos.Length; i++)

                {

                    objEmail.To.Add(new MailAddress(tos[i]));

                }

            }

            else

            {

                objEmail.To.Add(new MailAddress(toAddress));

            }

// if ccAddress Contains many email addresses seperated by ','

            if (!string.IsNullOrEmpty(ccAddress))

            {

                if (ccAddress.Contains(","))

                {

                    string[] ccs = ccAddress.Split(',');

                    for (int i = 0; i < ccs.Length; i++)

                    {

                        if (!string.IsNullOrEmpty(ccs[i]))

                            objEmail.CC.Add(new MailAddress(ccs[i]));

                    }

                }

                else

                {

                    objEmail.CC.Add(new MailAddress(ccAddress));

                }

            }

            objEmail.Body = body;

            objEmail.Subject = subject;

            objEmail.IsBodyHtml = true;

          //Adding Attachments to the Email, Itemattachment is SPListItem which contains Attachments

            foreach (string fileName in Itemattachment.Attachments)

            {

              string attachPath=  Itemattachment.Attachments.UrlPrefix + fileName;

              WebClient webAttach = new WebClient();

              webAttach.UseDefaultCredentials = true;

              var stream = webAttach.OpenRead(attachPath);

              Attachment attached = new Attachment(stream, fileName);

              objEmail.Attachments.Add(attached);

            }

            smtp = new SmtpClient();

            smtp.Host = webapp.OutboundMailServiceInstance.Server.Address;

            smtp.Send(objEmail);

        }
