SQL Server Compact的Web Interface（WebMatrix）添加数据库条目不起作用

Question

我想弄清楚我的代码做错了什么（如下所示）。我尝试了几种不同的方法并在线搜索了几种方法，但我似乎无法找出为什么这段代码不会在我的数据库中添加条目。我使用WebMatrix（用于Web界面的cshtml，使用C＃）和SQL Server Compact数据库。我对使用带有数据库的Web界面非常陌生。非常感谢任何帮助！

我认为您不需要渲染页面中的代码，但如果需要，我会提供它们（它们只是链接，头部和一些常见的结束标记，用于为页面制作未来的页脚）。 / p>

当我提交表单时，似乎没有任何事情发生（除了重新加载页面），但数据库中没有添加的条目。再一次，你必须原谅我，我是新人，所以如果我遗漏了一些非常明显的东西，我道歉，但我根本找不到解决办法。谢谢！

Answer 1

好的，请允许我回答我自己的问题，因为这可能是我可以挽回自己的唯一方法来解决这个错误所带来的疏忽，并希望能够为任何可能受益的人提供一个教训。

我无法相信我忽略了这一点，但我在表单的末尾应用了一个简单的“按钮”元素，而不是明显需要的输入类型=“提交”按钮。这当然从未允许实际提交表格。

经验教训：无论我们对事物进行多少次编码，无论我们一百次完成任务的一年级是多少，总是有机会进行简单的监督，无论是疲劳，最后期限，或者只是简单的自满。

当所有其他方法都失败时，请再次阅读您的代码，如果必须，请排队，因为我们都犯了那些花费我们大量时间的简单错误，只需重新阅读所有代码有时会导致最快的修复。

感谢任何试图提供帮助的人！
