Question

我通过填写IEnumerable的{{1}}列表来启动INDEX页面。然后，将模型发送到INDEX视图。底部的照片通过两个文本框和下拉列表显示了INDEX的外观。

一旦按下提交按钮，我希望将信息打印在ABOUT页面中，以确保信息正在传输。具体来说，我希望从DropDownListFor()中选择SelectedListItem的TEXT。

我尝试使用行DropDownListFor()将所选值的TEXT传输到ABOUT View。这在ABOUT默认操作中，但是它永远不会返回我设置的字符串。为什么我的input.SelectedText = input.SelectedType.Text;不转账？

模型

SelectedListItem

控制器

public class UserInputModel
    {
        public SelectListItem SelectedType { get; set; }
        public IEnumerable<SelectListItem> Type { get; set; }
        public string SelectedText { get; set; }
        [Required]
        public string Path { get; set; }
        [Required]
        public string Find{ get; set; }


        public IEnumerable<SelectListItem> FillType(IEnumerable<SelectListItem> list)
        {
            list = new[]
            {
                    new SelectListItem { Value = "1", Text = "Xml" },
                    new SelectListItem { Value = "2", Text = "Html" },
                    new SelectListItem { Value = "3", Text = "Css" },
                    new SelectListItem { Value = "4", Text = "C#" }

            };
            return list;
        }
}

查看“索引”

public class FindController : Controller
    {

        public ActionResult Index()
        {
            var input = new UserInputModel();
            input.Type=input.FillType(input.Type);
            return View(input);
        }

        [HttpPost]
        public ActionResult Index(UserInputModel input)
        {

            return View("About", input);
        }

        public ActionResult About(UserInputModel input)
        {


            input.SelectedText = input.SelectedType.Text;
            return View(input); 
        }
    }

INDEX View

ABOUT View

由于这是我第一次与MVC合作，因此有关良好和不良做法的任何其他反馈都将有所帮助。

如何访问并确认我的SelectedListItem TEXT从我的下拉列表从一个视图转移到另一个视图？
