Email

[Morris Neuman]

Hi,

I want to have a function where the user can enter an email address and then
send email with a selected file as an attachment.

Can you show me any walkthroughs or document where this is done?

 

[Nathan Sokalski]

Do you know how to send an email in ASP.NET at all, or is it only the
attaching a file that you need help with? The two main classes you will need
to deal with are:

System.Net.Mail.SmtpClient
System.Net.Mail.MailMessage

All you need to do with the SmtpClient is pass it a String in the
constructor specifying the SMTP server. Most of the properties of
MailMessage should be pretty self-explanatory. To add a file to the
MailMessage as an attachment, use the Add method of the Attachments
property. Once you have set all the desired properties of the MailMessage,
use a statement similar to the following to send it:

yoursmtp.Send(yourmailmsg)

Hopefully this helps!

Hi Morris,

As for sending email in ASP.NET web page(with attachment), I think you need
to implement such a web page via the following approach:

** Your page will need some FileUpload controls to let user first add some
attachments. These operation will post back to server so as to save all the
attachments to a temp folder on server(for later email sending use). For
ASP.NET file uploading, you can refer to the below article:

#File Upload with ASP.NET
http://www.codeproject.com/KB/aspnet/fileupload.aspx

** After you've file uploading functionality on page, you can add code to
send email. In .net 2.0, you can use Sysetem.Net.Mail classes to send
email(also support add attachments). There are many samples here for your
reference:

http://weblogs.asp.net/scottgu/archive/2005/12/10/432854.aspx

http://aspnet.4guysfromrolla.com/articles/072606-1.aspx



And I've also found a code project article which combine the above two
parts. I think it is quite close to what you want.

Thanks. Got the basics of the email working.

One question:
Is there a way the user enter several email addresses in textbox1, each
address seperated by a semicolon, set EmailTo = textbox1.Text and then add
entire string to message.To.Add(new MailAddress(EmailTo1))?

I get error doing this and have to parse the textbox1.Text string and do an
message.To.Add(new...) for each address.

If you separate the addresses by a comma rather than a semicolon you can
simply do the following:

message.To.Add(textbox1.Text)

If the addresses are separated by a semicolon, you can simply modify this
statement by using the String.Replace() method as follows:

message.To.Add(textbox1.Text.Replace(";",","))

There is no need to manually parse the addresses (although this wouldn't be
that hard using the String.Split() method and a simple loop). Hopefully this
helps.

Thanks for Nathan's input.

Nice solution. By using the Replace method, we can avoid parsing the multi
address (via split) and join them again with the new separator.

Thanks for the response. I tried your suggestion and entered in multiple
email addresses followed by comma, I even tried with and with a space after
the comma.
However in both cases, the first recipient receives the email but the second
one does not.
In debugging I do see that Textbox1.Text = "(e-mail address removed),
(e-mail address removed)", and the message To Count =1 showing just the first
email address.

When the first recipient gets the message, the to address in the email
received only has the 1 email address.

Is there something else I have to do to allow user to input multiple email
address and the send to all in the input list?

 

[Steven Cheng]

Thanks for your reply Morris,

Then, I think we'd better still use the stereotype code to add multiple
receivers:

=============================
public static void SendMail()
{
string receivers =
"(e-mail address removed);[email protected];[email protected]";

MailMessage msg = new MailMessage();
msg.From = new MailAddress("(e-mail address removed)");

foreach (string rec in receivers.Split(';'))
{
msg.To.Add(rec);
}

msg.Subject = "This is just a test message!";
msg.Body = "Sorry for the inconvenience.";

SmtpClient client = new SmtpClient("smtphost");
client.UseDefaultCredentials = true;
client.Send(msg);
}
==============================

Hope this helps.
