带有停用代码的多个收件人的电子邮件 [英] Email with multiple receipients with deactivation code
问题描述
嗨;
我正在网上购物网站。在这个网站上我有电子邮件新闻订阅表格。
在管理方面，管理员可以从网格中选择多个电子邮件用msg和内容发送。我想发送包含新闻订阅停用代码的内容。
在我的表格中我使用以下代码
protected void dlContactus_ItemCommand（object source，DataListCommandEventArgs e）
{
blErr.Items.Clear（）;
开关（e.CommandName）
{
案例发送：
CheckBox chk;
HiddenField hd;
StringBuilder sb = new StringBuilder（）;
foreach（dlContactus.Items中的DataListItem项）
{
chk =（CheckBox）item.FindControl（chk）;
如果（chk == null）
继续;
如果（chk.Checked == false）
继续;
hd =（HiddenField）item.FindControl（hd）;
sb.AppendFormat（{0};，hd.Value）;
}
if（sb.ToString（）！= string.Empty）
{
string strTo = sb.ToString（）;
if（strTo.Substring（strTo。长度 - 1,1）==，）
strTo = strTo.Remove（strTo.Length - 1,1）;
string Body = txtContent.Text
Common.SendBulkMail（ConfigurationManager.AppSettings [_ ADMIN_MAIL_ID]，strTo，txtSubject.Value，正文，真实，虚假）;
blErr.Items.Add（通讯发送给选定的客户）;
}
e lse
{
blErr.Items.Add（未选择电子邮件地址）;
}
休息;
}
}
.....................
i希望向相应的用户发送带有http：//site/page.aspx？id = email等停用代码的内容。每个用户都有单独的停用代码。
如果我为每个用户使用发送功能需要很多时间。快速完成任务的方法。

StringBuilder sb = new StringBuilder();
foreach (DataListItem item in dlContactus.Items)
{
chk = (CheckBox)item.FindControl("chk");
if (chk == null)
continue;
if (chk.Checked == false)
continue;
hd = (HiddenField)item.FindControl("hd");
sb.AppendFormat("{0};", hd.Value);
}
if (sb.ToString() != string.Empty)
{
string strTo = sb.ToString();
if (strTo.Substring(strTo.Length - 1, 1) == ",")
strTo = strTo.Remove(strTo.Length - 1, 1);
string Body = txtContent.Text
Common.SendBulkMail(ConfigurationManager.AppSettings["_ADMIN_MAIL_ID"], strTo, txtSubject.Value, Body, true, false);

if i use send function for each user it takes lot of time.any method to do it fast.
推荐答案
如果每个用户的代码不同，原则上它不能是多个收件人电子邮件。每个用户都应该收到单独的消息。就如此容易。尽可能快。 :-)
至于性能，你会浪费时间撰写邮件，这与发送邮件无关。您只需要编写一次消息，并且对于每次发送，只需快速插入两个（左右）参数：To地址和停用代码。一条消息不是一块纯文本，所以你总能做到。

If the code is different for each user, it cannot be a "multiple recipient e-mail" in principle. Each user should get a separate message. As simple as that. And as fast as it can be. :-)
As to the performance, you waste time on composing a message, which has nothing to do with sending it. You need to compose a message just once, and for each send, just quickly insert two (or so) parameters: "To" address and deactivation code. A message is nothing by a block of plain text, so you always can do it.
