Re: Sending a E-mail in C# - C# Discussion Boards

8-May-08 0:21

Hi,

Can someone try to tell me the definitive (like, yeah) way of sending a mail in c# from my website. I'm .NET2, Visual Sudio 2005 and have a 3 simple textboxs and a send button on my site for people to get in touch. I want it to send me the text1 as a subject, text2 as the body, text3 as their mail address (which they have manually typed in)

Obviously I've been round the web.....

private void Button1_Click(object sender, System.EventArgs e)
{
MailMessage mail = new MailMessage();
mail.To = txtTo.Text;
mail.From = txtFrom.Text;
mail.Subject = txtSubject.Text;
mail.Body = txtBody.Text;
SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(mail);
}

these seem out of date, and how do I test locally on my machine? Do I put 'localhost' as my SMTP server? until it goes live?

Any help would be great.

Thanks

Harvey

This is obsolete now. Use classes in System.Net.Mail namespace. You can configure System.Net.Mail settings on the app.config file and put the server name as localhost. Stop local SMTP server and set mail delivery type as PickupDirectoryFromIis which will deliver mails to the pickup directory.

Thanks for that,

In the new classes I cannot find where I specify the SMTP server name. Any ideas?

Plus 'localhost' always returns an error.

Then I guess you found where to put it ? You need an actual mail server, in order to send mail.

Yeah, thanks.

Why is everyone mentioning 'localhost' if it's not a vaible option i wonder? Can I just use any server until I put it live?

Thanks

It's possible to set up a mail server on our local machine. You can put whatever you like, but it won't work, obviously.

imnotso#8-May-08 1:57

8-May-08 1:57

I'm not sure how it can be tested then without putting it live, that cannot be right surely?

Christian Graus8-May-08 2:17

How do you hope to send mail, without a mail server ? You cannot. I don't see the issue, your mail server is not 'live', it's the server that sends your mail ( i.e. you can use the mail server from your ISP, the one that your Outlook uses ).

Just for testing purpose you can use localhost as server and delivery method as Pickup directory. So all the mails sent are kept in pickup directory as outlook file format. You can goto that directory and easily check the mail. Once you are ready to release the application, change delivery method to Network and specify valid SMTP server details and credentials. Read details about SMTPClient here[^]. Read and excellent FAQ on System.Net.Mail here[^]. Also this[^] explains how to configure your application configuration file.

what is regular expression correponding to this string [Select]?

I have a working version of an email client I made using smtp for C#. If you still need it, I can send you my sample code. As well, I would like to tell you that the server you are using is also important. I'm going to presume that you are going to use a free server, so your best bet would most likely be using Googlemail's smtp, since you actually forward your mail to their ports. As well, what you had before was to simple a method, if you're using an smtp server, you're going to have to authenticate each request, meaning that you'll also have to send your email's password.

"[Select]"

A regex can be anything you like, that is, there are many ways to match that string. The real question is, how closely do you need to match it, and what other strings would be OK ? Expresso is a tool you should download to help you learn regex

XML message generation

George_George7-May-08 23:25

7-May-08 23:25

Hello everyone,

I need to generate some XML message, but the message can not be reflected from members or properties of class instance directly.

Currently, I am using StringBuilder to append strings into XML message manually (e.g. to generate the element's hierarchies and add attributes to element), I think this method is stupid.

Any better approaches recommended?

thanks in advance,
George

XMLDocument can be better than StringBuilder...

Thanks natsuyaki,

1.

I read some documents for XMLDocument and XMLElement, looks like we need to use DOM model, right?

2.

I have not found some good samples for a beginner, I have XML knowledge before and just want to learn how to use the C# classes. Any referred samples?

regards,
George

Yes. XMLDocument use DOM. When file is loaded, it loads the entire file into memory. So if the file is very large, this method is inefficient. Calling Save() method on this class instance will save all the changes made to the instance.

I think MSDN has enough documentation on using these classes. It's pretty easy.

Thanks N a v a n e e t h,

XMLTextWriter will not use DOM model and only loads necessary nodes other than all nodes (which is done in DOM model)?

XMLTextWriter won't load any nodes. It is used to create XML documents. It has some methods which you can use to create nodes, attributes etc.

Sorry, N a v a n e e t h!

My bad, I mean XMLTextReader, it will not load the entire tree as DOM, like XMLDocument, and it will only loads necessary nodes, right?
