用System.Web.Mail发送邮件，适用于.net1.1，.net2.0请用System.Net.Mail

先引用System.Web
1，发送简单邮件

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 hereSmtpMail.Send( mail );

2，发送Html邮件

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.<br><b>this part is in bold</b>";

SmtpMail.SmtpServer = "localhost";

//your real server goes hereSmtpMail.Send( mail );

3,发送附件

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 attachmentmail.Attachments.Add( attachment );

//add the attachmentSmtpMail.SmtpServer = "localhost";

//your real server goes hereSmtpMail.Send( mail );

4，修改发件人和收件人的名称
比如发件人的地址是abc@126.com,我们用outlook收到信，From一栏里将直接显示abc@126.com.
能不能在From一栏里显示友好一点的名字呢？
比如显示Tony Gong

方法如下：

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 hereSmtpMail.Send( mail );

5,发送给多人

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 hereSmtpMail.Send( mail );

6，用需要Smtp验证的邮箱发信
现在为了防止垃圾邮件，绝大部分Smtp服务器需要验证了
发信方法如下：

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，以及使用SSL加密
大部分smtp服务器的端口是25，但有些却不是
同时，绝大部分Smtp服务器不需要SSL登陆，有些却需要
比如Gmail，smtp端口是：465，同时支持SSL
代码如下：

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 );
