.net发送邮件的一些技巧_.net资料_编程技术-你的首页-uuhomepage.com
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 hereSmtpMail.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 hereSmtpMail.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.
this part is in bold";SmtpMail.SmtpServer = "localhost"; //your real server goes hereSmtpMail.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.Htmlmail.Body = "this is my test email body.
this part is in bold"SmtpMail.SmtpServer = "localhost" 'your real server goes hereSmtpMail.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 attachmentmail.Attachments.Add( attachment ); //add the attachmentSmtpMail.SmtpServer = "localhost"; //your real server goes hereSmtpMail.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 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：[ 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 hereSmtpMail.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 hereSmtpMail.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 hereSmtpMail.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 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：
[ 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)
