.net发送邮件的一些技巧

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 );

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)

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 );

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)

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 );

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
