用System.Web.Mail發送郵件，適用於.net1.1，.net2.0請用System.Net.Mail
先引用System.Web
1，發送簡單郵件
[ C# ] MailMessage mail = new MailMessage();
mail.To = "[email protected]";
mail.From = "[email protected]";
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 = "[email protected]"
mail.From = "[email protected]"
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)
這裡的smtpserver只能是那些不需要驗證的smtp伺服器，像是126,sina,yahoo等等的信箱，都需要驗證，所以不能用。用這些信箱寄信後面會講到
2，發送Html郵件
[ C# ]
MailMessage mail = new MailMessage();
mail.To = "[email protected]";
mail.From = "[email protected]";
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 = "[email protected]"
mail.From = "[email protected]"
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,發送附件
[ C# ] MailMessage mail = new MailMessage();
mail.To = "[email protected]";
mail.From = "[email protected]";
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 = "[email protected]"
mail.From = "[email protected]"
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，修改寄件者和收件人的名稱例如寄件人的地址是[email protected],我們用outlook收到信，From一欄裡將直接顯示[email protected].
能不能在From一欄顯示友善一點的名字呢？
例如顯示Tony Gong
方法如下：
[ C# ]
MailMessage mail = new MailMessage();
mail.To = ""John" <[email protected]>";
mail.From = ""Tony Gong" <[email protected]>";
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"" <[email protected]>"
mail.From = """Tony Gong"" <[email protected]>"
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,發送給多人
[ C# ] MailMessage mail = new MailMessage();
mail.To = "[email protected];[email protected];[email protected]";
mail.From = "[email protected]";
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 = "[email protected];[email protected];[email protected]"
mail.From = "[email protected]"
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驗證的郵件信箱寄信現在為了防止垃圾郵件，絕大部分Smtp伺服器需要驗證了寄信方法如下：
[ C# ] MailMessage mail = new MailMessage();
mail.To = "[email protected]";
mail.From = "[email protected]";
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 = "[email protected]"
mail.From = "[email protected]"
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伺服器的端口，以及使用SSL加密大部分smtp伺服器的端口是25，但有些卻不是同時，絕大部分Smtp伺服器不需要SSL登陸，有些卻需要比如Gmail，smtp端口是：465，同時支援SSL
程式碼如下：
[ C# ]
MailMessage mail = new MailMessage();
mail.To = "[email protected]";
mail.From = "[email protected]";
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 = "[email protected]"
mail.From = "[email protected]"
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)
