Как отправить электронное письмо с вложениями в SharePoint 2013?
Вопрос
Я использую SharePoint 2013 для реализации приложения пользовательского рабочего процесса.
Во время одного из переходов состояния я хочу отправить электронное письмо людям, которые являются частью определенной группы с ZIP-файлом документов, загруженных за последние 5 дней.
Тем не менее, я не уверен, какой лучший способ отправлять вложения в SharePoint.Я не мог найти, поддерживается ли он сам API:
Пожалуйста, предложите, какой будет рекомендуемый путь.

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();
}
}
