Microsoft Graph upload large files

I am developing an aplication that send and email with one or multiple attachments via Microsoft Graph, but when try to upload file send me an error: ": Invalid total bytes specified in the Content-Range header"
i asume that i must specifi Range Value in same where, but no idea.
This is my code:
private static async void SenMailUsingMicrosoftGraph(List<String>Destinations, List<String>Cc, string HidenCopy, string Body, string Title, List<FileInfo>Filess);
{
ClientSecretCredential credential = new ClientSecretCredential("MyTenantID", "MyClientId", "MyClientSecret");
List<Recipient> recipientsDestinatarios = new List<Recipient>();
List<Recipient> recipientsCopias = new List<Recipient>();
foreach (var c in Destinations)
{
recipientsDestinatarios.Add(
new Recipient
{
EmailAddress = new EmailAddress
{
Address = c
}
});
}
foreach (var mail in Cc)
{
recipientsCopias.Add(
new Recipient
{
EmailAddress = new EmailAddress
{
Address = mail
}
});
}
#endregion
var message = new Microsoft.Graph.Message
{
Subject = Title,
Body = new ItemBody
{
ContentType = BodyType.Html,
Content = Body
},
ToRecipients = recipientsDestinatarios
,
CcRecipients = recipientsCopias
,
BccRecipients = new List<Recipient>()
{
new Recipient
{
EmailAddress=new EmailAddress{Address=Hiden}
}
}
};
GraphServiceClient graphClient = new GraphServiceClient(credential);
#endregion
#region adjuntar ficheros
var msgResult = await graphClient.Users["myemail#mycompany.com"].MailFolders.Drafts.Messages
.Request()
.WithMaxRetry(9)
.AddAsync(message);
foreach (var Archivo in Filess)
{
var attachmentContentSize = Archivo.Length;
var attachmentItem = new AttachmentItem
{
AttachmentType = AttachmentType.File,
Name = Archivo.Name,
Size = attachmentContentSize,
};
//initiate the upload session for large files
var uploadSession = await graphClient.Users["myemail#mycompany.com"].Messages[msgResult.Id].Attachments
.CreateUploadSession(attachmentItem)
.Request()
.PostAsync();
var maxChunkSize = 1024 * 320;
var allBytes = System.IO.File.ReadAllBytes(Archivo.FullName);
using (var stream = new MemoryStream(allBytes))
{
stream.Position = 0;
LargeFileUploadTask<FileAttachment> largeFileUploadTask = new LargeFileUploadTask<FileAttachment>(uploadSession, stream, maxChunkSize);
await largeFileUploadTask.UploadAsync();
}
}
await graphClient.Users["myemail#mycompany.com"].Messages[msgResult.Id].Send().Request().PostAsync();
}
I try something like this:
var content = new System.Net.Http.Headers.ContentRangeHeaderValue(0,MyFile.Length-1,MyFile.Length);
but i dont now how to asign this content variable, i think that must go in the uploadSession but dont know how.
------------------------------------EDIT------------------------------
included a Picture where see that the size of the attachment is not zero

Send Generated Pdf as Email Attachment Asp.NetCore

I am using Rotativa to convert my view to pdf. I would like to send that generated pdf as an email attachment (without having to download it first to disk). I've been following a bunch of tutorials to do this but I just keep going round in circles. I would much appreciate any help I can get.
public async Task<IActionResult>SomeReport()
{
...
return new ViewAsPdf (report)
}
return view();
MemoryStream memoryStream = new MemoryStream();
MimeMessage msg = new MimeMessage();
MailboxAddress from = new MailboxAddress ("Name", "emailAddress")
msg.From.Add(from);
MailboxAddress to = new MailboxAddress ("Name", "emailAddress")
msg.From.Add(to);
BodyBuilder bd = new BodyBuilder();
bb.HtmlBody ="some text";
bb.Attachments.Add("attachmentName", new MemoryStream());
msg.Body = bb.ToMessageBody();
SmtpClient smtp = new SmtpClient();
smtp.Connect("smtp.gmail.com",465, true);
smtp.Authenticate("emailAddress", "Pwd");
smtp.Send(msg);
smtp.Disconnect(true);
smtp.Dispose();
Edit
Parent View from which Email is sent
#Model MyProject.Models.EntityViewModel
<a asp-action= "SendPdfMail" asp-controller ="Student" asp-route-id = "#Model.Student.StudentId">Email</a>
...
SendPdfMail action in Student Controller
public async Task<IActionResult> SendPdfMail(string id)
{
var student = await context.Student. Where(s => s.StudentId == id);
if (student != null)
{
...
var viewAsPdf = new ViewAsPdf("MyPdfView", new{route = id})
{
Model = new EntityViewModel(),
FileName = PdfFileName,
...
}
}
};

Complete answer using Rotativa.AspNetCore. Code is developed in VS 2019, Core 3.1, Rotativa.AspNetCore 1.1.1.
Nuget
Install-package Rotativa.AspNetCore
Sample controller
public class SendPdfController : ControllerBase
{
private const string PdfFileName = "test.pdf";
private readonly SmtpClient _smtpClient;
public SendPdfController(SmtpClient smtpClient)
{
_smtpClient = smtpClient;
}
[HttpGet("SendPdfMail")] // https://localhost:5001/SendPdfMail
public async Task<IActionResult> SendPdfMail()
{
using var mailMessage = new MailMessage();
mailMessage.To.Add(new MailAddress("a#b.c"));
mailMessage.From = new MailAddress("c#d.e");
mailMessage.Subject = "mail subject here";
var viewAsPdf = new ViewAsPdf("view name", <YOUR MODEL HERE>)
{
FileName = PdfFileName,
PageSize = Size.A4,
PageMargins = { Left = 1, Right = 1 }
};
var pdfBytes = await viewAsPdf.BuildFile(ControllerContext);
using var attachment = new Attachment(new MemoryStream(pdfBytes), PdfFileName);
mailMessage.Attachments.Add(attachment);
_smtpClient.Send(mailMessage); // _smtpClient will be disposed by container
return new OkResult();
}
}
Options class
public class SmtpOptions
{
public string Host { get; set; }
public int Port { get; set; }
public string Username { get; set; }
public string Password { get; set; }
}
In Startup#ConfigureServices
services.Configure<SmtpOptions>(Configuration.GetSection("Smtp"));
// SmtpClient is not thread-safe, hence transient
services.AddTransient(provider =>
{
var smtpOptions = provider.GetService<IOptions<SmtpOptions>>().Value;
return new SmtpClient(smtpOptions.Host, smtpOptions.Port)
{
// Credentials and EnableSsl here when required
};
});
appsettings.json
{
"Smtp": {
"Host": "SMTP HOST HERE",
"Port": PORT NUMBER HERE,
"Username": "USERNAME HERE",
"Password": "PASSWORD HERE"
}
}

There's not quite enough to go on, but you need something like this:
MimeMessage msg = new MimeMessage();
MailboxAddress from = new MailboxAddress ("Name", "emailAddress");
msg.From.Add(from);
MailboxAddress to = new MailboxAddress ("Name", "emailAddress");
msg.To.Add(to);
BodyBuilder bb = new BodyBuilder();
bb.HtmlBody ="some text";
using (var wc = new WebClient())
{
bb.Attachments.Add("attachmentName",wc.DownloadData("Url for your view goes here"));
}
msg.Body = bb.ToMessageBody();
using (var smtp = new SmtpClient())
{
smtp.Connect("smtp.gmail.com",465, true);
smtp.Authenticate("emailAddress", "Pwd");
smtp.Send(msg);
smtp.Disconnect(true);
}
Notice this adds the attachment before calling .ToMessageBody(), as well as fixing at least four basic typos.
But I doubt this will be enough... I suspect ViewAsPdf() needs more context than you get from a single DownloadData() request, and you'll need to go back to the drawing board to be able to provide that context, but this at least will help push you in the right direction.

Create a list of disposable emails

I'm sending emails with asp.net core 2.0 like this
public string EmailServiceSend(string body, string subject = null, string to = null,
string multipleRecipients = null, string attachmentUrl = null, string smtpClient = null,
string userCredential = null, string userPassword = null, string from = null, bool template = false,
string templateRoute = null)
{
try
{
SmtpClient client = new SmtpClient("mysmtpserver");
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("username", "password");
MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress("whoever#me.com");
mailMessage.To.Add("receiver#me.com");
mailMessage.Body = body;
mailMessage.Subject = subject;
client.Send(mailMessage);
}
catch(Exception ex)
{
ex.Message.ToString();
}
return "Email sended"
}
I want to know, how can I create a list of email domains to block and send an error message. For example I want to block this domains:
0-mail.com
0815.ru
0clickemail.com
0wnd.net
and then send a response into my return statement for example:
if(listofblockmails == true){
return "You can't add this email domain, change it please"
}
How can I achieve that? Regards

Try using Linq:
Lets say you have this List:
List<string> listofblockmails = new List<string>();
listofblockmails.Add("0-mail.com");
listofblockmails.Add("0815.ru");
listofblockmails.Add("0clickemail.com");
listofblockmails.Add("0wnd.net");
You can do as below:
if (listofblockmails.Contains("emailToBeChecked.com"))
{
//return "You can't add this email domain, change it please";
}
else
{
//send
//return "Email sended";
}
And let Garbage collector do the disposal.

You can simply parse the email address and get the domain part, and compare againist a list of bad domains. If the domain is present in your bad domain list, return messge.
You can create a method like this.
private bool IsGoodDomain(string email)
{
if (string.IsNullOrEmpty(email))
return false;
var badDomains = new List<string>
{
"0815.ru",
"0wnd.net"
};
var r = email.Split('#');
if (!r.Any()) return false;
var domainName = r.Last();
return !badDomains.Contains(domainName, StringComparer.InvariantCultureIgnoreCase);
}
and call this method in your other method
if(IsGoodDomain(someEmailAddressVariable))
{
//contnue sending
}
else
{
// return the error message
}

Lumisoft.net IMAP server can't add attachments to messages

I'm trying to set up an IMAP server which is pulling data from a SQL database.
I've got the messages working no problems, but I can't work out how to attach attachments to them.
The attachments object on the Mail_Message object also only has a getter and a method called GetAttachments() which doesn't seem to connect to anywhere.
My current code is:
//this is my own object I'm using to pull data from the database
var cmMsg = _ml.GetMessage(mId, session.AuthenticatedUserIdentity.Name, -1);
var msgBody = new MIME_b_Text(MIME_MediaTypes.Text.html);
var msg = new Mail_Message();
msg.Body = msgBody;
msg.To = new Mail_t_AddressList();
msg.From = new Mail_t_MailboxList {new Mail_t_Mailbox(cmMsg.From, cmMsg.FromEmail)};
msg.Cc = new Mail_t_AddressList();
msg.Bcc = new Mail_t_AddressList();
foreach (var recipient in cmMsg.Recipients)
{
if (recipient.isTo)
{
msg.To.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
else if(recipient.isCC)
{
msg.Cc.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
else if (recipient.isBCC)
{
msg.Bcc.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
}
//I tried adding a setter to the attachment object, but just get errors with this code
var a = new List<MIME_Entity>();
foreach (var attachment in cmMsg.Attachments)
{
var aCT = new MIME_b_Multipart(new MIME_h_ContentType("application/octet-stream"));
a.Add(new MIME_Entity
{
Body = aCT,
ContentDisposition = new MIME_h_ContentDisposition("attachment"),
});
}
msg.Attachments = a.ToArray();
msg.Subject = cmMsg.Subject;
msg.Date = cmMsg.TimeDate;
msg.MessageID = cmMsg.InternetMessageId;
if (e.FetchDataType == IMAP_Fetch_DataType.MessageStructure)
{
}
else if(e.FetchDataType == IMAP_Fetch_DataType.MessageHeader)
{
}
else
{
msgBody.SetText(MIME_TransferEncodings.QuotedPrintable, Encoding.UTF8, cmMsg.HtmlBody);
_da.MarkAsRead(archiveID, session.AuthenticatedUserIdentity.Name);
}
e.AddData(info, msg);
I'm not sure if I'm missing something or just got this set up wrong. I noticed there was a MySQL API in the example projects, but that didn't have anything to do with attachments in it either.

Ok so turns out I was going about it the complete wrong way. Below is the code required
Effectively, it requires setting the message to be multipart mixes instead of just text. You can then add the attachments as a body part.
var cmMsg = _ml.GetMessage(mId, session.AuthenticatedUserIdentity.Name, -1);
MIME_h_ContentType contentType_multipartMixed = new MIME_h_ContentType(MIME_MediaTypes.Multipart.mixed);
contentType_multipartMixed.Param_Boundary = Guid.NewGuid().ToString().Replace('-', '.');
MIME_b_MultipartMixed multipartMixed = new MIME_b_MultipartMixed(contentType_multipartMixed);
var msg = new Mail_Message();
msg.To = new Mail_t_AddressList();
msg.From = new Mail_t_MailboxList {new Mail_t_Mailbox(cmMsg.From, cmMsg.FromEmail)};
msg.Cc = new Mail_t_AddressList();
msg.Bcc = new Mail_t_AddressList();
msg.Body = multipartMixed;
foreach (var recipient in cmMsg.Recipients)
{
if (recipient.isTo)
{
msg.To.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
else if(recipient.isCC)
{
msg.Cc.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
else if (recipient.isBCC)
{
msg.Bcc.Add(new Mail_t_Mailbox(recipient.FullName, recipient.SMTPAddress));
}
}
msg.Subject = cmMsg.Subject;
msg.Date = cmMsg.TimeDate;
msg.MessageID = cmMsg.InternetMessageId;
msg.MimeVersion = "1.0";
msg.Header.Add(new MIME_h_Unstructured("X-MS-Has-Attach", "yes"));
if (e.FetchDataType == IMAP_Fetch_DataType.MessageStructure)
{
}
else if(e.FetchDataType == IMAP_Fetch_DataType.MessageHeader)
{
}
else
{
MIME_Entity entity_text_plain = new MIME_Entity();
MIME_b_Text text_plain = new MIME_b_Text(MIME_MediaTypes.Text.plain);
entity_text_plain.Body = text_plain;
text_plain.SetText(MIME_TransferEncodings.QuotedPrintable, Encoding.UTF8, cmMsg.HtmlBody);
multipartMixed.BodyParts.Add(entity_text_plain);
foreach (var attachment in cmMsg.Attachments)
{
using (var fs = new FileStream(#"C:\test.txt", FileMode.Open))
{
multipartMixed.BodyParts.Add(Mail_Message.CreateAttachment(fs, "test.txt"));
}
}
}
e.AddData(info, msg);

C# Outlook send one email to multiple recipients

i have been trying to figure out how to send outlook email via C# to multiple recipients. For now i can do a loop among the recipients, but there is going to a lot of sent emails in my sent box.
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
oMsg.HTMLBody ="test";
oMsg.Subject = "test" ;
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx#xxx.com");
oRecip.Resolve();
oMsg.Send();
oRecip = null;
oRecips = null;
oMsg = null;
oApp = null;
If i add multiple address to it like:
(Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx#xxx.com,yyy#yyy.com,zzz#zzz.com")
This will not work somehow. Can anyone help me on this?

You just need to separate each user by a semicolon. For example look at my code below.
Outlook.MailItem mail = null;
Outlook.Application objApp = new Outlook.Application();
mail=(Outlook.MailItem)objApp.CreateItem(Outlook.OlItemType.olMailItem);
mail.Subject ="HI";
mail.To = "personone#yahoo.com; Persontwo#yahoo.com";
mail.Attachments.Add("C:\SOME_FOLDER\SomeFile");
mail.Body="xxxxxx";
mail.Send();

("xxx#example.com,yyy#example.org,zzz#meta.example.com") isn't the divider a semi-colon as in
("xxx#example.com; yyy#example.org; zzz#meta.example.com") ??
If I go into my Outlook and send to multiple people it's a semi-colon displayed in the to: field.

Why not just call "oRecips.Add" for each recipient? After all it's ADDING to the RECIPIENTS...?
EDIT: Just verified:
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
oMsg.HTMLBody = "test";
oMsg.Subject = "test";
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;
foreach (var recipient in new string[] { "a#b.c", "c#d.e" })
{
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add(recipient);
oRecip.Resolve();
}
oRecips = null;
oMsg.Send();
oMsg = null;
oApp = null;
will create ONE sent item with any number of recipients, just like I thought.

This code is working fine for sending multiple recipients
private static void SendMail(string body){
try { string tomail = System.Configuration.ConfigurationManager.AppSettings["ToMailString"];
string[] allToAddresses = tomail.Split(";,".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
Microsoft.Office.Interop.Outlook.Application oApp = (Microsoft.Office.Interop.Outlook.Application)Marshal.GetActiveObject("Outlook.Application");
//Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
//Microsoft.Office.Interop.Outlook.MailItem tempItem = (Microsoft.Office.Interop.Outlook.MailItem)Globals.ThisAddIn.Application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
Microsoft.Office.Interop.Outlook.MailItem email = (Microsoft.Office.Interop.Outlook.MailItem)(oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem));
email.Subject = "Status Report";
email.Body = body;
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)email.Recipients;
int mailcount1 = 1;
for (; mailcount1 < allToAddresses.Length; mailcount1++)
{
if (allToAddresses[mailcount1].Trim() != "")
{
//email.Recipients.Add(allToAddresses[mailcount1]);
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add(allToAddresses[mailcount1]);
oRecip.Resolve();
}
}
oRecips = null;
((Microsoft.Office.Interop.Outlook.MailItem)email).Send();
Console.WriteLine("Mail Sent");
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}

try this code if you want to send multiple persons add them in cc or bcc or to as your wish
public void SendAutomatedEmail(string htmlString, string subject, string from, string fromPwd, string recipient)
{
try
{
string mailServer = "xxxxExchangesver.com";
string[] allToAddresses = recipient.Split(";,".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
MailMessage message = new MailMessage(from, allToAddresses[0]);
int mailcount1 = 1;
for (; mailcount1 < allToAddresses.Length; mailcount1++)
{
if (allToAddresses[mailcount1].Trim() != "")
message.To.Add(allToAddresses[mailcount1]);
}
message.IsBodyHtml = true;
message.Body = htmlString;
message.Subject = subject;
message.CC.Add(from);
SmtpClient client = new SmtpClient(mailServer);
var AuthenticationDetails = new NetworkCredential(from, fromPwd);
client.Credentials = AuthenticationDetails;
client.EnableSsl = true;
client.Send(message);
client.Dispose();
}
catch (Exception e)
{
status(e.Message, Color.Red);
}
}
