将 name 属性添加到您的输入字段，例如：

If you declare all your controls in the view inside the
如果您在视图中声明所有控件
@using (Html.BeginForm())
{
//Controls...
}
ASP.NET (WebPages, MVC, RAZOR) uses HTTP protocol as base for the interactions between client and server. And to make HTTP pass client-side values to the server-side all HTML elements must have name attributes defined. The id attribute in HTML element is just for the front-end use. (CSS, JavaScript, JQuery, etc.). See the below lines of code for a working example;
ASP.NET（WebPages、MVC、RAZOR）使用 HTTP 协议作为客户端和服务器之间交互的基础。并且要使 HTTP 将客户端值传递到服务器端，所有 HTML 元素都必须定义名称属性。HTML 元素中的 id 属性仅供前端使用。（CSS、JavaScript、JQuery 等）。有关工作示例，请参阅以下代码行；
<input type="text" name="zzzz" id="xxxx"/>
Then in the controller you can access the controls with FormCollection object. It includes all controls described with a name attribute.
然后在控制器中，您可以使用 FormCollection 对象访问控件。它包括用 name 属性描述的所有控件。
//
// POST:
[HttpPost]
public ActionResult CreatePortal(FormCollection formCollection)
{
// You can access your controls' values as the line below.
string txtValue = formCollection["zzzz"];
//Here is you code...
}

To Get the HTML Control Value in the Controller through Form collection, You need to add "name" attribute to your HTML Controls.
要通过表单集合获取控制器中的 HTML 控件值，您需要向 HTML 控件添加“名称”属性。
