我试图弄清楚我的代码做错了什么（位于下面）。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此代码不会将条目添加到我的数据库中。我将 WebMatrix（用于 Web 界面的 cshtml，使用 C#）与 SQL Server Compact 数据库一起使用。我对使用带有数据库的 Web 界面非常陌生。任何帮助深表感谢！

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、头部部分和一些常见的结束标签，用于为页面制作未来的页脚）。

当我提交表单时，似乎什么都没有发生（除了重新加载页面），但数据库中没有添加条目。再说一次，你必须原谅我，我是新手，所以如果我遗漏了一些非常明显的东西，我很抱歉，但我根本无法找到解决方案。谢谢！

好的，请允许我回答我自己的问题，因为这可能是我弥补自己因疏忽而陷入此错误并希望为任何可能受益的人提供教训的唯一方法。

我不敢相信我忽略了这一点，但我在表单末尾应用了一个简单的“按钮”元素，而不是明显需要的输入 type="submit" 按钮。这当然不允许实际提交表单。

教训：无论我们编写多少次代码，无论我们完成了一百次的任务是多么一年级，总是有可能出现简单的疏忽，无论是由于疲劳、截止日期还是单纯的疏忽自满。

当所有其他方法都失败时，请再次阅读您的代码，如果必须的话，逐行阅读，因为我们都犯过那些花费我们大量时间的简单错误，并且简单地重新阅读所有代码有时可以导致最快的修复.

感谢任何试图提供帮助的人！
