vs2003 和vs2005下的发送SMTP邮件 （downmoon原创）
一、vs2003
引用 System.Web.Mail命名空间

private void SenMail2003()
... {
MailMessagemailObj = new MailMessage();
mailObj.To = this .txtTo.Text;
mailObj.From = this .txtFrom.Text;

mailObj.Subject = " 精采笑话 " ;
mailObj.Body = " 猪！你已中毒!哈哈 " ;

mailObj.BodyFormat = MailFormat.Html;
mailObj.BodyEncoding = MailFormat.Base64;
mailObj.Priority = MailPriority.High;
mailObj.Attachments.Add( new MailAttachment( " c:/swf/000.bmp " ));
SmtpMail.Send(mailObj);
Response.Write( " 发送邮件成功！ " );
}

二、vs2005
引用 System.Net.Mail命名空间,安全性得到了增强

public static void SendWebMailAndAttach( string server)
{
string file = " e:/inetpub/wwwroot/Test2005All/TestXML/testXML.xml " ;
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage( " [e-mail] " , " [e-mail] " , " text message for you. " , " Test Title " );
System.Net.Mail.Attachment data = new System.Net.Mail.Attachment(file, System.Net.Mime.MediaTypeNames.Application.Octet);
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(file);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
message.Attachments.Add(data);
System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(server);
client.Credentials = new NetworkCredential( " 用户名 " , " 密码 " );
client.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;//这句是关键
client.Send(message);
data.Dispose();
}

引用示例

SendWebMailAndAttach("smtp.126.com");
