Question

我目前正在从事一个项目，该项目需要我保存用户输入的送货地址数据，并将其保存到会话中。我需要将数据存储在会话中，因为稍后需要在“谢谢”页面中显示此数据。

这是我的模特

public class DeliveryAddressModel
{
    [Required(ErrorMessage = "Please enter a name")]
    public string Name { get; set; }

    [Required(ErrorMessage = "Please enter the first address line")]
    [Display(Name = "Line 1")]
    public string Line1 { get; set; }
    [Display(Name = "Line 2")]
    public string Line2 { get; set; }
    [Display(Name = "Line 3")]
    public string Line3 { get; set; }

    [Required(ErrorMessage = "Please enter a city name")]
    public string City { get; set; }

    [Required(ErrorMessage = "Please enter a state name")]
    public string State { get; set; }

    public string Zip { get; set; }

    [Required(ErrorMessage = "Please enter a country name")]
    public string Country { get; set; }

这是我的观点

@using (Html.BeginForm()) 
{
@Html.AntiForgeryToken()

<div class="form-horizontal">
    <h4>DeliveryAddressModel</h4>
    <hr />
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })

            <input type="submit" value="Create" class="btn btn-default" />
        </div>
    </div>
</div>
}

我的控制器

public class DeliveryAddressController : Controller
{
    // GET: DeliveryAddress
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Address(DeliveryAddressModel dam)
    {


        Session["Name"] = dam.Name;
        Session["Line1"] = dam.Line1;
        Session["Line2"] = dam.Line2;
        Session["Line3"] = dam.Line3;
        Session["City"] = dam.City;
        Session["State"] = dam.State;
        Session["Zip"] = dam.Zip;
        Session["Country "] = dam.Country;

        return View(dam);
    }

}

我将如何使我的控制器存储数据以供以后使用？如果还有其他更简单的方法，请告诉我。我是MVC的新手。

根据您在那里的“查看”结果初始化DeliveryAddressModel对象。

[HttpPost]
public ActionResult Index(DeliveryAddressModel dam)
{
    //Set this to the results sent back from your controller.

    Session["Name"] = dam.Name();
    Session["Line1"] = dam.Line1();
    Session["Line2"] = dam.Line2();
    Session["Line3"] = dam.Line3();
    .
    .
    .
    Session["Country "] = dam.Country();
    return View();
}

然后，您可以访问Session对象，直到用户关闭其浏览器。

在“谢谢”页面视图中，您可以通过以下方式访问会话：

@Session["Country"]

如何将输入数据保存到模型中，然后将其存储在会话中以供以后使用MVC显示？
