net System.Web.Mail发送邮件

用System.Web.Mail发送电子邮件.net1.1。net2.0请用System.Net.Mail

先引用System.Web

1，发送简单的电子邮件

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com";

mail.From = "you@yourcompany.com";

mail.Subject = "this is a test email.";

mail.Body = "this is my test email body";

SmtpMail.SmtpServer = "localhost"; //your real server goes here

SmtpMail.Send( mail );

这里的smtpserver仅那些不需要验证的smtp服务器，如126,sina,yahoo等待的电子邮件地址都需要验证，因此无法使用。稍后将讨论使用这些电子邮件地址发送电子邮件

2，发送Html邮件

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com";

mail.From = "you@yourcompany.com";

mail.Subject = "this is a test email.";

mail.BodyFormat = MailFormat.Html;

mail.Body = "this is my test email body.
this part is in bold";

SmtpMail.SmtpServer = "localhost"; //your real server goes here

SmtpMail.Send( mail );

3,发送附件

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com";

mail.From = "you@yourcompany.com";

mail.Subject = "this is a test email.";

mail.Body = "this is my test email body.";

MailAttachment attachment = new MailAttachment( Server.MapPath( "test.txt" ) ); //create the attachment

mail.Attachments.Add( attachment ); //add the attachment

SmtpMail.SmtpServer = "localhost"; //your real server goes here

SmtpMail.Send( mail );

4修改发件人和收件人的姓名

例如，发件人的地址是abc@126.com,我们用outlook收到信，From该列将直接显示abc@126.com.

能不能在From一列中显示的友好名称呢？

比如显示Tony Gong

方法如下：

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "\"John\" me@mycompany.com";

mail.From = "\"Tony Gong\" you@yourcompany.com";

mail.Subject = "this is a test email.";

mail.Body = "this is my test email body.";

SmtpMail.SmtpServer = "localhost"; //your real server goes here

SmtpMail.Send( mail );

5,发送给多人

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com;him@hiscompany.com;her@hercompany.com";

mail.From = "you@yourcompany.com";

mail.Subject = "this is a test email.";

mail.Body = "this is my test email body.";

SmtpMail.SmtpServer = "localhost"; //your real server goes here

SmtpMail.Send( mail );

6，用需要Smtp已验证的电子邮件发送

现在，为了防止垃圾邮件，绝大多数Smtp服务器需要验证

发送方式如下：

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com";

mail.From = "abc@126.com";

mail.Subject = "this is a test email.";

mail.Body = "Some text goes here";

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc"); //set your username here

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "your password"); //set your password here

SmtpMail.SmtpServer = "smtp.126.com"; //your real server goes here

SmtpMail.Send( mail );

7,修改smtp服务器的端口及其用法SSL加密

大部分smtp服务器的端口是25但有些不是

同时，绝大多数Smtp服务器不需要SSL登录，有些需要

比如Gmail，smtp端口是：465，同时还支持SSL

代码如下：

[ C# ]

MailMessage mail = new MailMessage();

mail.To = "me@mycompany.com";

mail.From = "abc@126.com";

mail.Subject = "this is a test email.";

mail.Body = "Some text goes here";

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc"); //set your username here

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "your password"); //set your password here

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport",465);

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true");

SmtpMail.SmtpServer = "smtp.126.com"; //your real server goes here

SmtpMail.Send( mail );
