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?

List<SendGrid.Helpers.Mail.Attachment> attachments = new List<SendGrid.Helpers.Mail.Attachment>();
SendGrid.Helpers.Mail.Attachment attach = null;
//The total size of your email, including attachments, must be less than 30MB.
foreach (string item in attachmentFilePaths)
{
var stream = File.OpenRead(item);
//string[] contentArray = fileName.Split('.');
//string contentType = contentArray[1].ToString();
var streamCount = stream.ToString();
System.IO.BinaryReader br = new System.IO.BinaryReader(stream);
byte[] bytes = br.ReadBytes((Int32)stream.Length);
string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
string[] filePathArray = item.Split('\\');
string fileName = filePathArray.LastOrDefault();
attach = new SendGrid.Helpers.Mail.Attachment() { Filename = fileName, Content= base64String };
attachments.Add(attach);
}
var from = new EmailAddress(DefaultSenderEmailAddress);
var msg = MailHelper.CreateSingleEmailToMultipleRecipients(from, recipientEmailList, subject, string.Empty, htmlContent, showAllRecipients = false);
MailHelper.CreateSingleEmailToMultipleRecipients(from, recipientEmailList, subject, string.Empty, htmlContent, showAllRecipients = false).AddAttachments(attachments);
var response = await this.SendGridClient.SendEmailAsync(msg);

I'm expecting to send multiple attachments in my email, using the Send Grid Api

I am trying to get DeviceToken of device in Xamarin iOS through RegisteredForRemoteNotifications and save it to Preferences, through API I save DeviceToken to database Server.
AppDelegate.cs
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
byte[] bytes = deviceToken.ToArray<byte>();
string[] hexArray = bytes.Select(b => b.ToString("x2")).ToArray();
DeviceToken = string.Join(string.Empty, hexArray);
Preferences.Set("TokenDevice", DeviceToken);
}
I have saved the DeviceToken to the database, the DeviceToken of the device I get:
6b60feecad920471ccde5a3447ab22d3f820abae821daeac726cc7e6d0863465
I wrote an API to send notifications to that device:
[HttpPost]
public void SendNotification(string devicetoken, string title, string body, string link, string icon)
{
try
{
dynamic data = new
{
to = devicetoken, // Uncoment this if you want to test for single device
// registration_ids = singlebatch, // this is for multiple user
priority = "high",
notification = new
{
title = title, // Notification title
body = body, // Notification body data
link = link, // When click on notification user redirect to this link
icon = icon
}
};
//var serializer = new JavaScriptSerializer();
var json = JsonConvert.SerializeObject(data);
Byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(json);
string SERVER_API_KEY = "AAAAqOId6Is:APA91bHJ5pQgLlanU8gwQwnpxdBlKS00i1xxxxxxxxxxxxxxxxxxxxxxxxxxx";
string SENDER_ID = "72xxxxxxxx";
WebRequest tRequest;
tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/json";
tRequest.Headers.Add(string.Format("Authorization: key={0}", SERVER_API_KEY));
tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close();
dataStream.Close();
tResponse.Close();
}
catch (Exception)
{
throw;
}
}
Where: SERVER_API_KEY and SENDER_ID I got from in console.firebase.google.com/Project settings/Cloud Messaging
I tried to test the API that sends notifications to the device I get the error: {\"multicast_id\":7343900550378569449,\"success\":0,\"failure\":1,\"canonical_ids\":0, \"results\":[{\"error\":\"InvalidRegistration\"}]}
I referenced this article. However I want to use this code because it allows me to set the Notification link and icon. Is this an outdated notification code? I searched the forums, and didn't get any reasonable results. Looking forward to everyone's help.
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 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]'.

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 have a problem with getting profile image from Delve account. Here is the example of link which returns me photo when i put it into browser: https://orgname.sharepoint.com/_vti_bin/DelveApi.ashx/people/profileimage?userId=alias#org.com&size=L
Now I need to get this photo from code. I tried such way, that works perfect for external images not in Office365:
var credentials = new NetworkCredential("myemail", "password");
using (var handler = new HttpClientHandler { Credentials = credentials })
using (var client = new HttpClient(handler))
{
var bytes = await client.GetByteArrayAsync(url);
return Convert.ToBase64String(bytes);
}
But as responce I get html page with text like:
<H1>We can't sign you in</H1><p>Your browser is currently set to block cookies. You need to allow cookies to use this service.</p><p>Cookies are small text files stored on your computer that tell us when you're signed in. To learn how to allow cookies, check the online help in your web browser.</p>
I think it is related with Office365 Authorization, but I don`t know how to perform REST request to this url with my credentials...
Problem Solved, first we need to initialize SharePoint Context:
public ClientContext SetupSpContext()
{
// This builds the connection to the SP Online Server
var clientContext = new ClientContext(_sharePointCrmDocumentsSiteName);
var secureString = new SecureString();
foreach (var c in _sharePointCrmDocumentsPwd.ToCharArray()) secureString.AppendChar(c);
{
clientContext.Credentials = new SharePointOnlineCredentials(_sharePointCrmDocumentsLoginName, secureString);
}
var web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
return clientContext;
}
Then we can Get profile picture from Shrepoint using User email:
public string DownloadProfilePictureAsBase64(string email)
{
try
{
var pictureUrl = GetPictureUrl(email);
var fileInfo = File.OpenBinaryDirect(_sharePointContext, pictureUrl);
using (var memory = new MemoryStream())
{
var buffer = new byte[1000000];
int nread;
while ((nread = fileInfo.Stream.Read(buffer, 0, buffer.Length)) > 0)
{
memory.Write(buffer, 0, nread);
}
memory.Seek(0, SeekOrigin.Begin);
var buffer2 = new byte[memory.Length];
memory.Read(buffer2, 0, buffer2.Length);
return Convert.ToBase64String(buffer2);
}
}
catch (Exception ex)
{
Console.WriteLine($"Picture for user {email} can not be downloaded");
Console.WriteLine(ex.Message);
}
return null;
}
private string GetPictureUrl(string email)
{
string targetUser = $"i:0#.f|membership|{email}";
var peopleManager = new PeopleManager(_sharePointContext);
var personProperties = peopleManager.GetPropertiesFor(targetUser);
_sharePointContext.Load(personProperties, p => p.PictureUrl);
_sharePointContext.ExecuteQuery();
var pictureUri = new Uri(personProperties.PictureUrl);
var localPath = pictureUri.LocalPath.Replace("MThumb", "LThumb"); //Change size of the picture
return localPath;
}
You should Microsoft Graph to get a user's picture. https://graph.microsoft.com/v1.0/me/photo gets your metadata about the profile picture, and https://graph.microsoft.com/v1.0/me/photo/$value gets you the image. You need to use OAuth. See https://graph.microsoft.io/en-us/docs/api-reference/v1.0/api/profilephoto_get for more details.
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
}
