在C＃中使用SMTP发送电子邮件 [英] Send Email using SMTP in C#

问题描述

using System.Net;
using System.Net.Mail;
OpenFileDialog dlg = new OpenFileDialog();
 private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            string filename = dlg.FileName;
 
            try
            {
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
 
                mail.From = new MailAddress("[e-mail]");
                mail.To.Add("[e-mail]");
                mail.Subject = filename;
                mail.Body = "Report";
                Attachment attachment = new Attachment(filename);
                mail.Attachments.Add(attachment);
 
                SmtpServer.Port = 25;
                SmtpServer.Credentials = new System.Net.NetworkCredential("me", "password");
                SmtpServer.EnableSsl = true;
 
                SmtpServer.Send(mail);
            }

这些代码非常适用于但是，我只能发送纯文本作为电子邮件。如何发送带有格式功能的电子邮件，如Yahoo Mail中的粗体斜体颜色更改等。此外，我需要一个RichTextBox代码来包含所有这些按钮。



请帮助。

hope it helps :)

基本上，您需要多部分电子邮件;一个或多个部分可以是HTML。或RTF，我不推荐。对于电子邮件，内容类型应为：内容类型：multipart / alternative 或 multipart / mixed 。对于每个部分，内容类型应该是有效的MIME类型，例如 text / html 。



请请参阅：

http://en.wikipedia.org/wiki/MIME [ ^ ]，

http://en.wikipedia.org/wiki/HTML_email [ ^ ]。



在.NET中发送电子邮件：

http://msdn.microsoft.com/en-us/library/ system.net.mail.mailmessage.aspx [ ^ ]。



对于更复杂的情况，其中一个部分可以引用另一个部分，例如HTML中引用的图像，请看我最近的回答：

使用图像发送HTML附件 [ ^ ]。



本文中的源代码还说明了如何使用C＃编写多部分电子邮件。



请参阅此CodeProject文章：

使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ]。

Basically, you need multi-part e-mail; and one or more parts could be HTML. Or RTF, which I would not recommend. For the e-mail, the content type should be: Content-Type: multipart/alternative or multipart/mixed. For each part, the content type should be a valid MIME type, such as text/html.

Please see:
http://en.wikipedia.org/wiki/MIME[^],
http://en.wikipedia.org/wiki/HTML_email[^].

Sending e-mail in .NET:
http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.aspx[^].

For more complex cases where one part can reference another part, such as image referenced in HTML, please see my recent answer:
Sending HTML attachment with images[^].

The source code in this article also shows how to compose multipart e-mail using C#.

Please also see this CodeProject article:
Sending an Email in C# with or without attachments: generic routine.[^].
