BuildMails()
{
List < mailData > mails = new List < mailData > (); // mailData是一个email的实体类。
CEmail email = new CEmail();
string [] temps = this .TBtoemail.Text.Split( ' , ' , ' ; ' );
string configStr = ConfigurationManager.AppSettings[ " recommendSubject " ].ToString(); // 邮件主题是配置文件配置的。


for ( int i = 0 ; i < temps.Length; i ++ )
... {
// 实例化具体mail实例
if ( ! string .IsNullOrEmpty(temps[i].Trim()))
... {
mailData mail = new mailData();

// 如果地址中有字符
mail.Subject = string .Format(configStr, this .TBfriendname.Text, this .TBfromEmail.Text);
mail.Encode = string .Empty;
mail.SendTime = System.DateTime.Now;
mail.UserName = this .TBfriendname.Text;
mail.ApplicationName = " 0 " ; // 0为好友推荐
mail.SendTime = DateTime.Now;
mail.Content = this .content.Value;
mail.FromMail = this .TBfromEmail.Text;
mail.IPOuter = Context.Request.UserHostAddress;

mail.ToEmail = temps[i];
if (CEmail.validatEmail(temps[i].Trim()))
... {
mail.Available = true ;
}
else
... {
mail.Available = false ;

}
mails.Add(mail);
}
}
return mails;
} 2:具体的发送代码 多封邮件。参数是list类型。 public RecommendSend(List mailData mails)
{
foreach (mailData mail in mails)
... {
if (mail.Available)
RecommendSend(mail);
}

} 邮件发送方法 public RecommendSend(mailData mail)
{
try
... {
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(
EmailFrom, mail.ToEmail, mail.Subject, mail.Content);
message.BodyEncoding = System.Text.Encoding.UTF8;

System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(EmailHostName); // mail.itingwang.com邮件服务器
client.Credentials = new System.Net.NetworkCredential(EmailUserName, EmailPassword); // "servermgr@itingwang.com", ".itisservermgr"
client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; // 邮件通过网络发送到smtp服务器
client.Send(message);
mail.sendstatus = 1 ;
}
catch (Exception ex)
... {
mail.sendstatus = 0 ; // sendstatus为0,sendstatus = -1; 邮件发送失败
mail.ErrorMsg = ex.Message;
ApplicationLog.WriteError(ex.Message);
}
saveMail(mail);
} 1：发送到多个邮件地址.将多封邮件的信息放入泛型数组。/**////建立mail数组   。多个邮件地址又“，”，“；”隔开 protected ListmailData> BuildMails()    ...{        ListmailData> mails = new ListmailData>();   //mailData是一个email的实体类。        CEmai
