用电子邮件发送表单遇到问题我的用户填写了

Question

因此我的程序的主要目的是让用户填写我的网站上的请求表单。一旦网页表格填写完毕并且用户按下提交，我已经完成了，程序会将他们填写的信息发送到我的电子邮件中。

我遇到的两个主要问题是，除非用户附加Web表单不会发送的附件。这很糟糕，因为他们不这样做。所以我需要某种if语句表示程序仍然应该发送带有或不带附件。我希望将日期发送到发送给我自己的电子邮件中。我该如何做到这一点，以便日期发送到我的电子邮件中，第二次用户点击提交按钮。

我添加了下面的大部分代码。

感谢

要知道，当你的用户点击：

添加一行创建您的留言：sb.AppendFormat("<tr><td>User clicked submit on:</td><td>{0}</td></tr>", strUpLoadDateTime);在Submit_CLick1

为了防止发送电子邮件失败使得电子附件条件：

if (!string.IsNullOrWhiteSpace(strAttachment)) 
{ 
    /*** Added mail attachment handling ***/  
    System.Net.Mail.Attachment attachment; 
    attachment = new System.Net.Mail.Attachment(strAttachment); 
    mailMsg.Attachments.Add(attachment); 
}
