------解决方案--------------------
需要引用System.Web.Mail命名空间。引用该命名空间需要添加System.Web.Dll

MailMessage mail = new MailMessage();
mail.BodyFormat=MailFormat.Html;
mail.From = "some@server ";
mail.To= "some@server ";//多个收件人之间用分号分割
mail.Bcc= "some@server ";//密送
mail.Cc== "some@server ";//抄送
mail.Subject = "this is mail subject ";
mail.Body = "this is mail body ";
mail.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/smtpauthenticate ", "1 ");
mail.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/sendusername ", "username ");
mail.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/sendpassword ", "password);

System.Web.Mail.MailAttachment attachment=new MailAttachment( "c:\\1.txt ");
mail.Attachments.Add(attachment);
SmtpMail.SmtpServer = "10.2.140.100 ";
SmtpMail.Send(mail);
