我在asp.net中创建了一个网站，除了用户注册表单外，一切正常。我的表单不是将数据发送到数据库。我可以通过在数据库中创建用户信息来登录该网站。

有人可以帮助我纠正htis

使用SQL事件探查器拦截数据库调用。这将告诉您它是否甚至到达数据库。
如果是，可以从那里直接将语句复制到SQL Manager中并执行它。
在许多情况下，由于数据格式不正确，或者将null传递给非可空列。考虑到您也在传递日期，与数据库中的列定义相比，可能是格式错误。
如果以上所有方法都失败，发布数据库架构也会有所帮助。

我要检查的第一件事是甚至调用 send_data 方法。我们没有看到表单和给定的代码没有指出如何调用此方法。您是否有一个控制事件（如按钮点击）调用一个调用 send_data 方法的方法？如果是，控件是否将 AutoPostback 设置为 true ？
我建议在方法开始时设置一个断点并确保你到达那里。
