如何将表单值传递给.NET MVC中的Controller

Question

在ASP.net MVC中:

我应该如何/可以将表格数据(从视图)传递给控制器​​？

这就是我的方向:

• Controller Index函数将ViewModel对象传递给View.
• ViewModel对象包含分页列表以及一些SelectLists._ ViewModel对象还包含一个名为theFilter的自定义类.此类的目的是通过表单保存从视图发布的过滤器信息.
• 我希望Index [AcceptVerbs(HttpVerbs.Post)]函数接收填充了表单数据的填充对象,以及页码(就像现在一样)

以下是我的代码片段:

控制器/索引回发功能:

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(int? page, CaseFilter caseFilter)
    {
        const int pageSize = 10;
        var cases = caseRepo.FindAllCases();
        var paginatedCases = new PaginatedList<Case>(cases, page ?? 0, pageSize);
        return View(new CaseIndexViewModel(paginatedCases, caseFilter));
    }

过滤类:

public class CaseFilter
{
    int iVolume_id = 0,
        iSubject_id = 0;

    public CaseFilter() {

    }

    public int Volume_id { get { return iVolume_id; } set { iVolume_id = value; } }
    public int Subject_id { get { return iSubject_id; } set { iSubject_id = value; } }

}

而ViewModel类:

    public class CaseIndexViewModel
    {
    public PaginatedList<Case> PaginatedCases { get; private set; }
    public CaseFilter CaseFilter { get; private set; }

    public CaseIndexViewModel(PaginatedList<Case> paginatedCases, CaseFilter caseFilter)
    {

       PaginatedCases = paginatedCases;
       CaseFilter = caseFilter;
    }
}

基本上我试图避免使用Request.Form来填充Filter类,至少不要在Controller中使用它.

欢迎任何帮助,建议或推论!

[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(FormCollection collection)
    {
         string valueFromNameTextBox = collection["name"];
    }

您可以使用表单上所有输入的名称为此集合建立索引.
