In my view, users can search for a document and once they get the result, they can click on its id and they can download the document from specific url based on id: http://test.com/a.ashx?format=pdf&id={0}

For example, if the id is 10, then url to download document will be: http://test.com/a.ashx?format=pdf&id=10, and when user click on it they are able to download the document.

This is how it looks like in my view:

 foreach (var item in Model)

        {



                <td>

                    <a href=@string.Format("http://test.com/a.ashx?format=pdf&id={0}",item.id)>

                        @Html.DisplayFor(modelItem => item.id)

                    </a>

                </td>

        }

And below is my controller action for SendEmail.

I am able to send email to the user. But i am having problem with sending attachments.
My question is: how can i attach the document that comes with the url to the email?

 public static bool SendEmail(string SentTo, string Text, string cc)

    {



        MailMessage msg = new MailMessage();



        msg.From = new MailAddress("test@test.com");

        msg.To.Add(SentTo);

        msg.CC.Add(cc);

        msg.Subject = "test";

        msg.Body = Text;

        msg.IsBodyHtml = true;



        System.Net.Mail.Attachment attachment;

        attachment = new System.Net.Mail.Attachment(???);

        msg.Attachments.Add(attachment);



        SmtpClient client = new SmtpClient("mysmtp.test.com", 25);



        client.UseDefaultCredentials = false;

        client.EnableSsl = false;

        client.Credentials = new NetworkCredential("test", "test");

        client.DeliveryMethod = SmtpDeliveryMethod.Network;

        //client.EnableSsl = true;



        try

        {

            client.Send(msg);

        }

        catch (Exception)

        {

            return false;

        }

        return true;

    }

If the PDF file is generated on an external site, you will need to download it in some way, for this you can use WebClient:

var client = new WebClient();



// Download the PDF file from external site (pdfUrl) 

// to your local file system (pdfLocalFileName)

client.DownloadFile(pdfUrl, pdfLocalFileName);  

Then you can use it on Attachment:

attachment = new Attachment(pdfLocalFileName, MediaTypeNames.Application.Pdf);

msg.Attachments.Add(attachment)

Consider using Postal It's open source libriary for ASP.Net MVC allowing you to send emails very easy. For example to attach file you can use such code:

dynamic email = new Email("Example");

email.Attach(new Attachment("c:\attachment.txt"));

email.Send(); 

Also you may want to use HangFire to send email in background, please take a look at the Sending Mail in Background with ASP.NET MVC

Update: In order to get the PDF file path you can use Server.MapPath method to convert virtual path to the corresponding physical directory on the server.
