使用SmtpMail类阿
------解决方案--------------------
MailMessage email = new MailMessage();
email.To = "xxx@yyy.com ";
email.From = "xxxxxxxxxx ";
email.Subjec = "Test ";
email.Body = "dddddddddd\n\neeeeeeeeeeeeee\n\nfffffffffffffff ";
SmtpMail.Send(email);
------解决方案--------------------
用Jmail组件，引用到.net项目里面。
附类：
public class JMail
{
private string _ToEmail;
private string _ToName;
private string _FromEmail;
private string _FromName;
private string _UserName;
private string _Password;
private string _Subject;
private string _Body;
private string _Smtp;
public JMail()
{
}
public string ToEmail
{
get{return _ToEmail;}
set{_ToEmail = value;}
}
public string ToName
{
get{return _ToName;}
set{_ToName = value;}
}
public string FromEmail
{
get{return _FromEmail;}
set{_FromEmail = value;}
}
public string FromName
{
get{return _FromName;}
set{_FromName = value;}
}
public string UserName
{
get{return _UserName;}
set{_UserName = value;}
}
public string Password
{
get{return _Password;}
set{_Password = value;}
}
public string Subject
{
get{return _Subject;}
set{_Subject = value;}
}
public string Body
{
get{return _Body;}
set{_Body = value;}
}
public string Smtp
{
get{return _Smtp;}
set{_Smtp = value;}
}

public bool Send()
{
jmailNET.MessageClass jmail = new MessageClass();

jmail.Charset = "gb2312 ";
jmail.ContentType = "text/html ";
jmail.Logging = false;
jmail.Silent = true;
jmail.Priority = 3;

//发送者Email
jmail.MailServerUserName = _UserName;
jmail.MailServerPassWord = _Password;
jmail.From = _FromEmail;
jmail.FromName = _FromName;

//接收者Email
jmail.AddRecipient(_ToEmail, _ToName, " ");

//Email内容
jmail.Subject = _Subject;
jmail.AppendHTML(_Body);

bool ReturnValue = jmail.Send(_Smtp, false);
jmail.Close();
return ReturnValue;
}
------解决方案--------------------
jmail　可收发．
