net发送邮件1

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
[ 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 );


[ VB.NET ]

Dim mail As 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只能是那些不需要验证的smtp服务器，像126,sina,yahoo等等的邮箱，都需要验证，所以不能用。用这些邮箱发信后面会讲到


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.<br><b>this part is in bold</b> " ;
SmtpMail.SmtpServer = " localhost " ;   // your real server goes here
SmtpMail.Send( mail );



[ VB.NET ]
Dim mail As 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 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 );


[ VB.NET ]

Dim mail As 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. "
Dim attachment As 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：
[ 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 );

[ VB.NET ]
Dim mail As 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 );

[ VB.NET ]

Dim mail As 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)
