使用C＃发送电子邮件 [英] Sending E-mail using C#

问题描述

我需要通过我的C＃应用​​发送电子邮件。

我来自一个VB 6背景，并且对MAPI控件有很多糟糕的体验。
首先，MAPI不支持HTML电子邮件，其次，所有电子邮件都发送到我的默认邮件发件箱。所以我仍然需要点击发送接收。

如果我需要发送大量html身体电子邮件（100 - 200），那么最好的方法是C＃？

提前感谢

解决方案

.NET框架的 System.Net.Mail.MailMessage 类

您可以找到 MSDN文档在这里。

这是一个简单的例子（代码片段）：

 使用System.Net; 
使用System.Net.Mail; 
使用System.Net.Mime; 
 
 ... 
 try 
 {
 
 SmtpClient mySmtpClient = new SmtpClient（my.smtp.exampleserver.net）; 
 
 //设置smtp-client with basicAuthentication 
 mySmtpClient.UseDefaultCredentials = false; 
 System.Net.NetworkCredential basicAuthenticationInfo = new 
 System.Net.NetworkCredential（username，password）; 
 mySmtpClient.Credentials = basicAuthenticationInfo; 
 
 //从mailaddresses添加
 MailAddress from = new MailAddress（[e-mail]，TestFromName）; 
 MailAddress to = new MailAddress（[e-mail]，TestToName）; 
 MailMessage myMail = new System.Net.Mail.MailMessage（from，to）; 
 
 //添加ReplyTo 
 MailAddress replyto = new MailAddress（[e-mail]）; 
 myMail.ReplyToList.Add（replyTo）; 
 
 //设置主题和编码
 myMail.Subject =测试消息; 
 myMail.SubjectEncoding = System.Text.Encoding.UTF8; 
 
 //设置正文消息和编码
 myMail.Body =< b>测试邮件< / b>< br>使用< b> HTML< / b> ;. ; 
 myMail.BodyEncoding = System.Text.Encoding.UTF8; 
 // text或html 
 myMail.IsBodyHtml = true; 
 
 mySmtpClient.Send（myMail）; 
} 
 
 catch（SmtpException ex）
 {
抛出新的ApplicationException 
（SmtpException已发生：+ ex.Message）; 
} 
 catch（Exception ex）
 {
 throw ex; 
} 
  

I need to send email via my C# app.

I come from a VB 6 background and had a lot of bad experiences with the MAPI control. First of all, MAPI did not support HTML emails and second, all the emails were sent to my default mail outbox. So I still needed to click on send receive.

If I needed to send bulk html bodied emails (100 - 200), what would be the best way to do this in C#?

Thanks in advance.

解决方案

You could use the System.Net.Mail.MailMessage class of the .NET framework.

You can find the MSDN documentation here.

Here is a simple example (code snippet):

using System.Net;
using System.Net.Mail;
using System.Net.Mime;

...
try
{

   SmtpClient mySmtpClient = new SmtpClient("my.smtp.exampleserver.net");

    // set smtp-client with basicAuthentication
    mySmtpClient.UseDefaultCredentials = false;
   System.Net.NetworkCredential basicAuthenticationInfo = new
      System.Net.NetworkCredential("username", "password");
   mySmtpClient.Credentials = basicAuthenticationInfo;

   // add from,to mailaddresses
   MailAddress from = new MailAddress("[e-mail]", "TestFromName");
   MailAddress to = new MailAddress("[e-mail]", "TestToName");
   MailMessage myMail = new System.Net.Mail.MailMessage(from, to);

   // add ReplyTo
   MailAddress replyto = new MailAddress("[e-mail]");
   myMail.ReplyToList.Add(replyTo);

   // set subject and encoding
   myMail.Subject = "Test message";
   myMail.SubjectEncoding = System.Text.Encoding.UTF8;

   // set body-message and encoding
   myMail.Body = "<b>Test Mail</b><br>using <b>HTML</b>.";
   myMail.BodyEncoding = System.Text.Encoding.UTF8;
   // text or html
   myMail.IsBodyHtml = true;

   mySmtpClient.Send(myMail);
}

catch (SmtpException ex)
{
  throw new ApplicationException
    ("SmtpException has occured: " + ex.Message);
}
catch (Exception ex)
{
   throw ex;
}
