Come inviare e-mail con allegati in SharePoint 2013?

Question

Sto usando SharePoint 2013 per implementare un'applicazione di flusso di lavoro personalizzato.

Durante una delle transizioni statali, voglio inviare un'e-mail a persone che fanno parte di un determinato gruppo con un file ZIP di documenti caricato negli ultimi 5 giorni.

Tuttavia, non sono sicuro di quale sia il modo migliore per inviare allegati in SharePoint.Non ho trovato se è supportato dall'API stesso:

http://msdn.microsoft.COM / IT-US / Biblioteca / Microsoft.SharePoint.Unilities.sputlity.SendeMail.aspx

Si prega di suggerire quale sarebbe un modo consigliato.

Answer 1

SPUtility.SendEmail doesn't support sending attachments you will need to use the classes in the System.Net.Mail namespace.

Below is an example of how to do this, it is not functional as you will need to provide additional code to load your zip file as an SPFile object in order to call the OpenBinaryStream() method (or provide some other way of opening the zip file as a Stream). Also it will need additional error checking and such.

using(SPSite site = new SPSite("http://siteurl"))
{
  using(SPWeb web = site.OpenWeb())
   {
       // Check there is an email server configured
        if (SPUtility.IsEmailServerSet(web)) 
        {
            // Get the web app so we can get the email server SP is configured to use
            SPWebApplication webApp = web.Site.WebApplication; 

            // Get the mail server details
            string smtpServerAddress = webApp.OutboundMailServiceInstance.Server.Address;
            string fromAddress = webApp.OutboundMailSenderAddress;

            var email = new MailMessage();
            email.From = new MailAddress(fromAddress);

            // Your code to load the zip file as an SPFile              

            Stream contentStream = spFile.OpenBinaryStream();
            var attachment = new Attachment(contentStream, spFile.Name);
            email.Attachments.Add(attachment);

            email.Subject = "Your email subject";
            email.Body = "Your email body text";

            // Set up the mail server and sent the email
            SmtpClient mailServer = new SmtpClient(smtpServerAddress);
            mailServer.Credentials = CredentialCache.DefaultNetworkCredentials;
            mailServer.Send(email);
        }
   }
}

This should work:

using (SPSite site = new SPSite("http://website.com/sites/site"))
{
    using (SPWeb web = site.OpenWeb())
    {
        System.IO.MemoryStream ms = new System.IO.MemoryStream();
        System.IO.StreamWriter writer = new System.IO.StreamWriter(ms);
        writer.Write("Hello its my sample file");
        writer.Write(Environment.NewLine);
        writer.Write(Environment.NewLine);
        writer.Write("Hello its my sample file");
        writer.Flush();

        SPWebApplication webApp = web.Site.WebApplication;
        string smtpServerAddress = webApp.OutboundMailServiceInstance.Server.Address;
        string fromAddress = webApp.OutboundMailSenderAddress;

        ms.Position = 0;     // read from the start of what was written             

        System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Plain);

        MailMessage email = new MailMessage();
        email.From = new MailAddress(fromAddress);
        email.To.Add("myemail@gmail.com");           

        email.Attachments.Add(new Attachment(ms, "myfile.txt", "text/txt"));
        email.Subject = "Your email subject";
        email.Body = "Your email body text";

        // Set up the mail server and sent the email
        SmtpClient mailServer = new SmtpClient(smtpServerAddress);
        mailServer.Credentials = CredentialCache.DefaultNetworkCredentials;
        mailServer.Send(email);

        writer.Dispose();
        ms.Close();
    }
}
