I am trying to send an email via Mandrill.Net, and am getting stuck trying to add multiple attachments. I have got the following code that create the list of attachments as IEnumerable, but I am getting the error
Unable to cast object of type 'System.Collections.Generic.List`1[Mandrill.Models.Attachment]' to type 'System.Collections.Generic.IEnumerable`1[Mandrill.Models.EmailAttachment]'.
The code is below:
try
{
EmailService ems = new EmailService();
EmailMessage msg = new EmailMessage();
List<EmailAddress> ToAdd = new List<EmailAddress>();
EmailAddress MainTo = new EmailAddress();
MainTo.Email = qe.ToAddress;
MainTo.Type = "bcc";
ToAdd.Add(MainTo);
msg.FromEmail = qe.FromAddress;
msg.FromName = qe.FromName;
msg.AddHeader("Reply-To", qe.ReplyTo);
msg.To = ToAdd;
msg.Subject = qe.Subject;
msg.Html = qe.Body;
msg.TrackClicks = true;
msg.TrackOpens = true;
// Need to add in Email Attachments
List<EmailAttachment> lea = new QueuedEmailModels().GetEmailAttachmentsByQueuedEmailID(qe.QueuedEmailsID); // Gets List of Attachments in DB
List<Attachment> lma = new List<Attachment>();
foreach(BRPA.EmailAttachment ea in lea)
{
byte[] array = File.ReadAllBytes(System.Web.Hosting.HostingEnvironment.MapPath("~/UploadedFiles/" + ea.AttachmentID));
Attachment at = new Attachment
{
Content = Convert.ToBase64String(array),
Name = ea.AttachmentName,
Type = ""
};
lma.Add(at);
}
msg.Attachments = (IEnumerable<Mandrill.Models.EmailAttachment>)lma.AsEnumerable();
// End of Attachments
await ems.SendMailviaMandrill(msg);
qe.Status = "Sent";
qe.DateTimeSent = DateTime.Now.AddHours(2);
await ctx.SaveChangesAsync();
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Thanks

Oops - Found the answer.
I had a class for EmailAttachment that was overriding the Mandrill.Models.EmailAttachment.
Specified the full name and all is good.

I'm using the send grid api to send emails in my c# app, and I can't seem to figure out how to send an email with multiple attachments. I can send an email with a single attachement, but not multiple. I can see that there are four methods used for attachments(see below), but there is only one that allow you to send a list of attachements "IEnumerable attachments", however it's a return type is void. Can someone tell me how to send multiple attachments using the send gris api?

I'm expecting to send multiple attachments in my email, using the Send Grid Api
I have an Email Razor page that accesses a custom method to send and email. All code seems to be correct. The problem I am having is accessing the "IFormFile files". I have tried adding the code to a controller as well as adding the IFormFile files to the custom method. I just can seem to find the right way to hande IFormFile. Below is the code that I currently have. What I am looking for is to see if someone can help me with the IFormFile portion. The information on IFormFile that I have found hasn't helped me so far as it's usually only partial information...I am very new to MVC and IFormFile, so help is greatly appreciated!

I have to send an email from my ASP.NET MVC 2 contact form view page.I need a detail answer that describes how to create the model , the controller and the view for that purpose .. Here is the code i have given in my controller class's action method..
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult SendEMail(CareersEMailModel careersEMailModel,HttpPostedFileBase upload)
{
if (ModelState.IsValid)
{
bool isOK = false;
try
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("no-reply#abc.com", "Website contact form");
msg.To.Add("info#abc.com");
msg.Subject = "Resume";
string body = "Name:" + careersEMailModel.Name + "\n" + "Phone:" + careersEMailModel.Phone + "\n" + "Email:" + careersEMailModel.Email;
string file = careersEMailModel.Resume;
msg.Body = body;
msg.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient("mailserver_url.net", 25);
smtp.Send(msg);
msg.Dispose();
isOK = true;
CareersMessageModel rcpt = new CareersMessageModel();
rcpt.Title = "Email sent successfully!!";
rcpt.Content = "Your details has been received with great thanks.We'll contact you as soon as possible.";
return View("CareersMessage", rcpt);
}
catch (Exception ex)
{
CareersMessageModel err = new CareersMessageModel();
err.Title = "Sorry,Email sending failed!!!";
err.Content = "The website is having an error with sending this mail at this time.You can send an email to our address provided in our contact us form.Thank you.";
return View("CareersMessage", err);
}
}
else
{
return View();
}
}
For retrieving the uploaded file, you will need to do this
foreach (string file in Request.Files)
{
var uploadFile = Request.Files[file];
if (uploadFile.ContentLength == 0) continue;
string fileLocation = //File Location with file name, needs to be stored for temporary purpose
uploadFile.SaveAs(fileLocation);
}
Then with help of following code you can attach file
Attachment data = new Attachment(fileLocation, MediaTypeNames.Application.Octet);
message.Attachments.Add(data);
Once done with the email delete the file created on server.
Hope this answers your question
from MSDN
public static void CreateMessageWithAttachment(string server)
{
// Specify the file to be attached and sent.
// This example assumes that a file named Data.xls exists in the
// current working directory.
string file = "data.xls";
// Create a message and set up the recipients.
MailMessage message = new MailMessage(
"jane#contoso.com",
"ben#contoso.com",
"Quarterly data report.",
"See the attached spreadsheet.");
// Create the file attachment for this e-mail message.
Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
// Add time stamp information for the file.
ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(file);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
// Add the file attachment to this e-mail message.
message.Attachments.Add(data);
//Send the message.
SmtpClient client = new SmtpClient(server);
// Add credentials if the SMTP server requires them.
client.Credentials = CredentialCache.DefaultNetworkCredentials;
try {
client.Send(message);
}
catch (Exception ex) {
Console.WriteLine("Exception caught in CreateMessageWithAttachment(): {0}",
ex.ToString() );
}
// Display the values in the ContentDisposition for the attachment.
ContentDisposition cd = data.ContentDisposition;
Console.WriteLine("Content disposition");
Console.WriteLine(cd.ToString());
Console.WriteLine("File {0}", cd.FileName);
Console.WriteLine("Size {0}", cd.Size);
Console.WriteLine("Creation {0}", cd.CreationDate);
Console.WriteLine("Modification {0}", cd.ModificationDate);
Console.WriteLine("Read {0}", cd.ReadDate);
Console.WriteLine("Inline {0}", cd.Inline);
Console.WriteLine("Parameters: {0}", cd.Parameters.Count);
foreach (DictionaryEntry d in cd.Parameters)
{
Console.WriteLine("{0} = {1}", d.Key, d.Value);
}
data.Dispose();
}
EDIT:
the Attachment class accepts a stream. So try this. (i haven't tested it but it should give you the gist of what you need to do)
foreach (string fileName in Request.Files)
{
HttpPostedFile file = Request.Files[fileName];
Attachment data = new Attachment(file.InputStream, fileName);
// do stuff to attach it to the Mail Message
}
i have a mission to make a plug-in in crm 4 which should 1. put in the subject field of an email the name of the account and then 2. put the contact list of account to the cc field of the email.
the first thing i did and it work, but the second... not so much...
i have seen some samples but none of them was close to halp me...
i would like to have help and explain of how to find the list of the contact that belong to the account and then put the list in the cc field.
here is the begining...:
namespace mail
{
public class Class1 : IPlugin
{
public void Execute(IPluginExecutionContext context)
{
DynamicEntity entity = null;
if (context.InputParameters.Properties.Contains("Target") &&
context.InputParameters.Properties["Target"] is DynamicEntity)
{
entity = (DynamicEntity)context.InputParameters.Properties["Target"];
if (entity.Name != EntityName.account.ToString())
{
return;
}
}
else
{
return;
}
try
{
// updating the subject of the email
ICrmService service = context.CreateCrmService(true);
account accountRecord = (account)service.Retrieve("account", ((Key)entity.Properties["accountid"]).Value, new ColumnSet(new string[] { "name" }));
String str = String.Empty;
str = accountRecord.name.ToString();
DynamicEntity followup = new DynamicEntity();
followup.Name = EntityName.email.ToString();
followup.Properties = new PropertyCollection();
followup.Properties.Add(new StringProperty("subject", str));
//updating the CC of the email
TargetCreateDynamic targetCreate = new TargetCreateDynamic();
targetCreate.Entity = followup;
CreateRequest create = new CreateRequest();
create.Target = targetCreate;
CreateResponse created = (CreateResponse)service.Execute(create);
}
catch
{
throw new InvalidPluginExecutionException(
"An error occurred in the AccountUpdateHandler plug-in.");
}
}
}
}
You can try something like this,
List<BusinessEntity> contactList = GetNeededContacts(crmService, sourceEntity);
email targetEmail = GetTargetEmail(crmService, emailid);
foreach (DynamicEntity contact in contactList)
{
activityparty contActParty = new activityparty() { partyid = new Lookup("contact", contact.contactid.Value };
List<activityparty> tmpList = targetEmail.cc.ToList();
tmpList.Add(contActParty);
targetEmail.cc = tmpList.ToArray();
}
crmService.Update(targetEmail);
You only have to develop the function to get the contact, user or account references.

Sending Email in .NET Through Gmail
I have so many problems with sending mail through C#. I have tried forever on multiple apps and it never works....
Could someone PLEASE post some sample code that clearly labels where the sender and recipient go and offers help with the smtp sever dat or whatever!!
Something like this:
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage("sender#gmail.com", "recipient#example.com", "subject", "body");
System.Net.Mail.SmtpClient emailClient = new System.Net.Mail.SmtpClient("smtp.gmail.com", 465);
emailClient.Credentials = new System.Net.NetworkCredential("yourgmailusername", "yourpassword");
emailClient.Send(message);
Some code that I wrote some time ago for sending email through a webform:
//using System.Net.Mail;
MailMessage msg = new MailMessage();
msg.To.Add(RECIPIENT_ADDRESS); //note that you can add arbitrarily many recipient addresses
msg.From = new MailAddress(SENDER_ADDRESS, RECIPIENT_NAME, System.Text.Encoding.UTF8);
msg.Subject = SUBJECT
msg.SubjectEncoding = System.Text.Encoding.UTF8;
msg.Body = //SOME String
msg.BodyEncoding = System.Text.Encoding.UTF8;
msg.IsBodyHtml = false;
SmtpClient client = new SmtpClient();
client.Credentials = new System.Net.NetworkCredential(ADDRESS, PASSWORD);
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try
{
client.Send(msg);
}
catch (SmtpException ex)
{
throw; //or handle here
}
I made this class to send via my gmail account when in my dev environment and use the SMTP in my Web.Config when in production. Essentially the same as noblethrasher with some deployment comfort.
There is a flag for "mailConfigTest"
/// <summary>
/// Send Mail to using gmail in test, SMTP in production
/// </summary>
public class MailGen
{
bool _isTest = false;
public MailGen()
{
_isTest = (WebConfigurationManager.AppSettings["mailConfigTest"] == "true");
}
public void SendMessage(string toAddy, string fromAddy, string subject, string body)
{
string gmailUser = WebConfigurationManager.AppSettings["gmailUser"];
string gmailPass = WebConfigurationManager.AppSettings["gmailPass"];
string gmailAddy = WebConfigurationManager.AppSettings["gmailAddy"];
NetworkCredential loginInfo = new NetworkCredential(gmailUser, gmailPass);
MailMessage msg = new MailMessage();
SmtpClient client = null;
if (_isTest) fromAddy = gmailAddy;
msg.From = new MailAddress(fromAddy);
msg.To.Add(new MailAddress(toAddy));
msg.Subject = subject;
msg.Body = body;
msg.IsBodyHtml = true;
if (_isTest)
{
client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = loginInfo;
}
else
{
client = new SmtpClient(WebConfigurationManager.AppSettings["smtpServer"]);
}
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Send(msg);
}
}
