  正文: 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# ]
SEOver="function anonymous(){this.style.cursor='hand';}" title="Click to copy to clipboard" style="CURSOR: hand" onclick="function anonymous(){copyToClipboard(this);}">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.Smtphotoshop/ target=_blank class=infotextkey>pserver = "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)

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:
[ 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 );




[ VB.NET ]

Dim mail As 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:

[ 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 );








[ VB.NET ]


Dim mail As 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)
