如何对象保存在ASP.NET会话 [英] How to save object to session in ASP.NET

问题描述

我写Asp.Net MVC 4应用程序。我想保存模型对象的会话，然后从另一个页面访问它，但不知道该怎么做。可能吗？例如，某些code：

  [HttpPost]
    公众的ActionResult指数（EventDetails OBJ）
    {        如果（ModelState.IsValid）
        {
            会话[EventDetails] = OBJ;
            返回RedirectToAction（索引2，家）;
        }
       否则返回查看（）;
 

下面活动详情模型code：

 命名空间ProjectMVC.Models
{
    公共类EventDetails
    {
        [需要]
        公共字符串FirstTeamName {搞定;组; }
    }
}
 

所以我要救EventDetails反对会话，然后访问它在View像一个正常的对象。事情是这样的：

  @Session [EventDetails。FirstTeamName
 

解决方案

您需要将其绑定到一个ViewModel：

  VAR VM =（EventDetails）会议[EventDetails];
返回查看（VM）;
 

在你看来，你干脆：

  @model EventDetails@ Model.FirstTeamName
 

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();

Here Event details model code:

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

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

解决方案

You need to bind it to a ViewModel:

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

In your view you simply:

@model EventDetails

@Model.FirstTeamName
