using System.Net;
using System.Net.Mail;
发送邮件的配送信息写在web.config的
/>
你们怎么发的？速度如何？这慢的原因又出在那里？？
解决方案1:
///
/// 邮件实体
///
public struct DawnProMail
{
private string from;
///
/// 发送者邮箱
///
public string From
{
get { return from; }
set { from = value; }
}
private string to;
///
/// 收件者集合以；分号分隔
///
public string To
{
get { return to; }
set { to = value; }
}
private string fromDisplayName;
///
/// 发送者姓名
///
public string FromDisplayName
{
get { return fromDisplayName; }
set { fromDisplayName = value; }
}
private string subject;
///
/// 邮件标题
///
public string Subject
{
get { return subject; }
set { subject = value; }
}
private string body;
///
/// 邮件正文
///
public string Body
{
get { return body; }
set { body = value; }
}
}

解决方案3: 网上一般都有现成的方法，如果慢，请先排除外因，比如你机器本身的问题，你所在的网络的问题，然后检查你的代码有没有异常，查询数据库得到数据是否有问题等等。。
