推荐答案

你实际上在一个问一些事情问题，所以我必须打破它。这些将是相当高级别的步骤，希望足以让您走上正确的道路。如果你仍然陷入困境，那么可能会问一个与你坚持的步骤有关的问题...



1。电子邮件发送工具

考虑设置一个专门的类来处理电子邮件的发送。这个类看起来像这样：简单的SMTP E- C＃中的邮件发件人...控制台应用程序 [ ^ ]



2。数据库更改

您的用户表（类型位字段）上需要一个标记，表示他们是否已经验证了自己。



3。创建验证页面

创建一个新页面，该页面是链接的目标。此页面将检查用户ID的查询字符串（建议您加密这些字符串）。当他们输入密码时，它会对此进行验证，然后在新列上将其标记为已验证。



然后您只需在电子邮件正文中添加一个链接到上一页将用户ID作为加密参数。

You''re actually asking a several things in one question, so I''ll have to break it down. These will be fairly high level steps, hopefully enough to get you on the right path. If you''re still stuck then maybe ask a question related specifically to the step you''re stuck on...

1. Email Sending util
Consider setting up a dedicated class to handle the sending of email. This class will look something like this: Simple SMTP E-Mail Sender in C#… Console application[^]

2. Database change
You need a flag on your user table (field of type bit) which represents whether they''ve verified themselves or not.

3. Creating the verification page
Create a new page which is the target of the link. This page will check the query string (recommend you encrypt these) for the user''s id. When they enter their password it would validate this and then mark them as verified on the new column.

Then you just add a link in the email body to the above page with the user id as an encrypted parameter.

Hope that helps.
