subject line of email message - c#

I'm writing an asp.net mvc app. in c#, and I'm wondering if anybody can help me to understand, if it's possible to include an input from another field stored in the database, like a numeric or text string into a subject line of the email.
For example, along with the subject text, like "Your event registration" I'd like to add a "registartion ID" into a subject line of my email.
Right now i have a code in my emailhepler.cs:
public static void NotifyHtml(string toAddress, string subject, string body)
{
MailMessage message = new MailMessage();
message.To.Add(toAddress);
message.From = new MailAddress("coe-RoomReservations#coe.berkeley.edu");
message.Subject = subject;

Yes. When you call your method, you should be able to format your subject however you want. E.g.,
NotifyHtml("coe-RoomReservations#coe.berkeley.edu", string.format("#{0} Your event registration", registrationId), body);

message.Subject = String.Format("{0} : {1}", subject, registrationID);

Yes. Hope I didn't misunderstand your question. MailMessage.Subject is just a property of type String so you can include anything that's formatted as a string.
message.Subject = string.Format("Your event registration; registration id : {0}", registrationId);

Wrong email titles when sending mails multiple times

First of all, my apologies if this is a duplicate question. I have searched for it a lot, but couldn't find related issues.
So here's the problem: I am using SmtpClient and MailMessage class to send mails. I am passing the subject of the mail as a parameter in the mail sending method. First time the mail is sent with the proper subject (the one i sent as parameter). However, in all next emails, no matter what subject i put, the subject remains the same (the one used first time). The subject is set from inside of the method.
(Note: This is a WindowsForm application)
What i have tried is, creating another method named "Refresh()" which disposes the mail object and creates it again (with from and to info only). And call this method each time after a mail is sent. But it doesn't help with this problem.
Codes are given below:
Fields:
MailMessage message;
SmtpClient mailer;
string from = "sender email";
string pass = "sender pass";
string to = "rec email";
Constructor:
try
{
message = new MailMessage(from, to);
mailer = new SmtpClient("smtp.gmail.com", 587);
mailer.Credentials = new NetworkCredential(from, pass);
mailer.EnableSsl = true;
}
catch(Exception ex) { /*code to write log*/ }
Refresh method:
void RefreshMessage()
{
try
{
message.Subject = "";
message.Dispose();
message = new MailMessage(from, to);
}
catch(Exception ex) { /*write log*/ }
}
Method which is sending the mail:
internal void TextOnly(string sub, string bodyMessage)
{
try
{
message.Subject = sub;
message.Body = bodyMessage;
mailer.Send(message);
this.RefreshMessage();
}
catch (Exception ex) { /*write log*/ }
}
Example of how it's called:
m.TextOnly("Subject 1" , SomeStringMethod());
m.TextOnly("Another Title " + anyString, "Some string mail");
m.TextOnly("[TAG] Email subject goes here" , AnotherStringMethod());
Now no matter whatever subject is sent in the parameter, it will always send with subject "Subject 1" (from the example above). The body of the message is fine, only the subject is not right.
I have few other methods in the class (for other purposes like sending mails with attachments for example), where subject isn't passed as parameter but it's set directly from within the method (like message.Subject = "Example Sub" from within the method), in that case it works fine.
But in the case above, where the subject is passed to the method, the subject remains the same.
Like the comment section already stated, there is no reason to cache the message itself. Currently, you're disposing the message(which actually puts it in a unusable state) and then you recreate it. Check out more HERE. You can just as well simply create new objects and dispose of them after you're done so the Garbage Collector can release the resources as soon as possible.
Just utilize a simple method for constructing MailMessages and send them directly.
internal MailMessage ConstructTextMailMessage(MailAddress from, MailAddress to, string subject, string body)
{
return ConstructTextMailMessage(from.Address, to.Address, subject, body);
}
internal MailMessage ConstructTextMailMessage(string from, string to, string subject, string body)
{
return new MailMessage(from, to, subject, body);
}
And then:
var mailClient = new SmtpClient("smtp.gmail.com", 587);
mailClient.Credentials = new NetworkCredential(from, pass);
mailClient.EnableSsl = true;
mailClient.Send(ConstructTextMailMessage(from, to, "Subject 1", SomeStringMethod()));
mailClient.Send(ConstructTextMailMessage(from, to, "Another Title " + anyString, "Some string mail");
mailClient.Send(ConstructTextMailMessage(from, to, "[TAG] Email subject goes here", AnotherStringMethod());
If you have attachments in the MailMessage, you should call Dispose after using them to clear up the streams. Also, call Dispose on the SmtpClient when you're done using it.
I used the same functionality (SntpClient, MailMessage etc.) in one of my programms and it worked just fine:
SmtpClient client = new SmtpClient("host", port);
MailMessage mail;
MailAddress absender = new MailAddress("mail#adress.from");
foreach (string sub in Subjects)
{
mail = new MailMessage();
mail.IsBodyHtml = true;
mail.Subject = sub;
mail.From = absender;
mail.To.Add("mail#adress.to");
client.Send(mail);
}
Mybe you just need to make a new MailMessage-Object each time you "create" a E-Mail.

c# Send Email using Process.Start

I want to send simple email with no attachment using default email application.
I know it can be done using Process.Start, but I cannot get it to work. Here is what I have so far:
string mailto = string.Format("mailto:{0}?Subject={1}&Body={2}", "to#user.com", "Subject of message", "This is a body of a message");
System.Diagnostics.Process.Start(mailto);
But it simply opens Outlook message with pre-written text. I want to directly send this without having user to manually click "Send" button. What am I missing?
Thank you
You need to do this :
string mailto = string.Format("mailto:{0}?Subject={1}&Body={2}", "to#user.com", "Subject of message", "This is a body of a message");
mailto = Uri.EscapeUriString(mailto);
System.Diagnostics.Process.Start(mailto);
I'm not sure about Process.Start() this will probably always only open a mail message in the default Mail-App and not send it automatically.
But there may be two alternatives:
Send directly via SmtpClient Class
using Outlook.Interop
You need to do this:
SmtpClient m_objSmtpServer = new SmtpClient();
MailMessage objMail = new MailMessage();
m_objSmtpServer.Host = "YOURHOSTNAME";
m_objSmtpServer.Port = YOUR PORT NOS;
objMail.From = new MailAddress(fromaddress);
objMail.To.Add("TOADDRESS");
objMail.Subject = subject;
objMail.Body = description;
m_objSmtpServer.Send(objMail);

C# Webmail.Send method how to change person name

WebMail.SmtpServer = SmtpServer;
WebMail.UserName = SmtpUsername;
WebMail.Password = SmtpPassword;
WebMail.Send(
ReplayEmail,
subject,
body,
email
);
subject is for example "Ask specialist"
body is html body
email is for example "domain#domain.com"
email is send to for example "domain2#domain.com"
now when i send mail i get mail which is ok but as person who send mail I see "domain2#domain.com". how to change this?
mail now looks like
domain2#domain.com Ask specialist
i want name (Adoo for example) and mail like
Adoo Ask specialist
If I understand correctly, when setting up mail you can do :
mail.To = new MailAddress("domain2#domain.com", "Adoo");
or :
mail.To= #"\Adoo \ <domain2#domain.com>";
I'm assuming ReplayAddress is a System.Net.Mail.MailAddress defined in code somewhere else you haven't shown. MailAddress has a constructor which takes a string displayName which should do what you want if I understand you correctly - documentation on that is here.
Typically in SMTP you can create a friendly name by using a format like this:
WebMail.Send(
"\"Adoo\" <domain2#domain.com>",
subject,
body,
email
);
or you can use
mail.To= #""Adoo" <domain2#domain.com&gt";
You are using the WebMail class which takes a string for the .From property of the class. I would use the MailAddress class and do:
MailAddress from = new MailAddress("domain2#domain.com", "Adoo Ask specialist");

Ques regarding sending email to a specific user

So I just googled n found out this code:-
MailMessage message = new MailMessage ("abc#somedomain.com","administrator#anotherdomain.com","Testing","This is a test mail");
Now my ques:-
How do I send a nicely formatted Email with links and all instead of simple text "This is a test mail" ??
I don't wanna attach no file
You could send the message body as HTML which will allow you to have links and such:
var message = new MailMessage("abc#somedomain.com", "administrator#anotherdomain.com");
message.Subject = "Testing";
message.IsBodyHtml = true;
message.Body = "<html><body><div>Test message</div>some link</body></html>";

How to send email in richtext format to Outlook?

It works great to send emails (to Outlook) in HTML format by assigning the text/html content type string like so:
using (MailMessage message = new MailMessage())
{
message.From = new MailAddress("--#---.com");
message.ReplyTo = new MailAddress("--#---.com");
message.To.Add(new MailAddress("---#---.com"));
message.Subject = "This subject";
message.Body = "This content is in plain text";
message.IsBodyHtml = false;
string bodyHtml = "<p>This is the HTML <strong>content</strong>.</p>";
using (AlternateView altView = AlternateView.CreateAlternateViewFromString(bodyHtml,
new ContentType(MediaTypeNames.Text.Html)))
{
message.AlternateViews.Add(altView);
SmtpClient smtp = new SmtpClient(smtpAddress);
smtp.Send(message);
}
}
The email is correctly recognized as HTML in Outlook (2003).
But if I try rich text:
MediaTypeNames.RichText;
Outlook doesn't detect this, it falls back to plain text.
How do I send email in rich text format?
The bottom line is, you can't do this easily using System.Net.Mail.
The rich text in Outlook is sent as a winmail.dat file in the SMTP world (outside of Exchange).
The winmail.dat file is a TNEF message. So, you would need to create your richtext inside of the winmail.dat file (formatted to TNEF rules).
However, that's not all. Outlook uses a special version of compressed RTF, so, you would also need to compress your RTF down, before it's added to the winmail.dat file.
The bottom line, is this is difficult to do, and unless the client really, really needs this functionality, I would rethink it.
This isn't something you can do with a few lines of code in .NET.
You can also achieve this by adding another alternate view before your calendar view as below:
var body = AlternateView.CreateAlternateViewFromString(bodyHtml, new System.Net.Mime.ContentType("text/html"));
mailMessage.AlternateViews.Add(body);
This worked for me..
public void sendUsersMail(string recipientMailId, string ccMailList, string body, string subject)
{
try
{
MailMessage Msg = new MailMessage();
Msg.From = new MailAddress("norepl#xyz.com", "Tracker Tool");
Msg.To.Add(recipientMailId);
if (ccMailList != "")
Msg.CC.Add(ccMailList);
Msg.Subject = subject;
var AltBody = AlternateView.CreateAlternateViewFromString(body, new System.Net.Mime.ContentType("text/html"));
Msg.AlternateViews.Add(AltBody);
Msg.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("mail.xyz.com");
smtp.Send(Msg);
smtp.Dispose();
}
catch (Exception ex)
{
}
}
