如何在ASP.NET&中保存对象到会话在视图中访问它 [英] How to save object to session in ASP.NET & access it in View

问题描述

我正在编写Asp.Net MVC 4应用程序.我想将模型对象保存到会话中，然后从另一个页面访问它，但是不知道如何做.是否有可能?例如一些代码:

I am writing Asp.Net MVC 4 application. I want to save model object to session and then access it from another page but don't know how to do it. Is it possible? For example some code:

[HttpPost]
    public ActionResult Index(EventDetails obj)
    {

        if (ModelState.IsValid)
        {
            Session["EventDetails"] = obj;
            return RedirectToAction("Index2","Home");
        }
       else return View();

此处的事件详细信息模型代码:

Here Event details model code:

namespace ProjectMVC.Models
{
    public class EventDetails
    {
        [Required]
        public string FirstTeamName { get; set; }
    }
}

所以我想将EventDetails对象保存到会话中，然后像普通对象一样在View中访问它.像这样:

So I want to save EventDetails object to session and then access it in View like a normal object. Something like this:

@Session["EventDetails"].FirstTeamName

推荐答案

您需要将其绑定到ViewModel:

You need to bind it to a ViewModel:

var vm = (EventDetails)Session["EventDetails"];
return View(vm);

在您看来，您只需:

@model EventDetails

@Model.FirstTeamName
