将模型值传递给控制器​​方法？

Question

如何将此模型值从视图传递给控制器​​方法？

查看：

  @using (Html.BeginForm("SearchMethod", "Home", new { area = "Timetables" }))
                               {
                                @Html.TextBoxFor(modelItem => modelItem.Sessionstateadminroot.CourseSearchPara)
                                <button type="submit" >Search</button>
                               }

控制器方法：

[Route("SearchMethod/{searchpara=Test}")]
        public ActionResult SearchMethod(string searchpara) 
        {

这是一个简单的演示，传递包含另一个

的模型

   public class ParentModel
    {
        public ChildModel ChildModel { get; set; }
        public string Name { get; set; }

    }
    public class ChildModel
    {
        public string Name { get; set; }
    }

控制器：

public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ParentModel model = new ParentModel();
            model.Name = "Parent model";
            model.ChildModel = new ChildModel();
            model.ChildModel.Name = "Child Name";

            return View(model);
        }
        public ActionResult SearchMethod (ParentModel model)
        {
            var name = model.Name;
            var childName = model.ChildModel.Name;
            return View(model);
        }
        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }
 }

观点：

@model MVCModelDemo.Models.ParentModel //Note the model passed to the view here
@{

    ViewBag.Title = "Home Page";
}

@using (Html.BeginForm("SearchMethod", "Home", new { area = "" }))
{
    @Html.TextBoxFor(modelItem => modelItem.Name)
    @Html.TextBoxFor(modelItem => modelItem.ChildModel.Name)
    <button type="submit">Search</button>
}

我希望这可以帮助您理解模型，控制器和视图之间的关系
