查看传球只有第一个值MVC [英] View pass only first value MVC

问题描述

我需要一些帮助，我的项目。
它我的视图模型：

I need some help with my project. Its my ViewModel:

public class ServiceView
{
    public IList<Service> Services { get; set; }
}

动作：

public Actionresult Swap()
{
    var services = from proj in db.Service select proj;
            ServiceView model = new ServiceView();
            model.Services = services.ToList();
            return View(model);
}

查看，其中显示的服务：

View where displays services:

@model proj.Models.ServiceView
@using(Html.BeginForm("SelectServices" , "AdditionalServices"))
{
    for (int i = 0; i < Model.Services.Count; i++)
    {
        <td>Name: @Html.DisplayFor(m => Model.Services[i].Name) </td>
        <td>Price:@Html.DisplayFor(m => Model.Services[i].Price)</td>
        <td>
            @Html.HiddenFor(m => Model.Services[i].Name)
            @Html.HiddenFor(m => Model.Services[i].Price)
            <input type="submit" id="submit" name="submit" value="Add"/>
        </td>
    }
}

帖子 - 动作：

Post - Action:

[HttpPost]
public ActionResult SelectServices(ServiceView serviceView)
{
    for (int i = 0; i < serviceView.Services.Count; i++)
    {
        return RedirectToAction("Pool", "Rank",
            new
            {
            serviceName = serviceView.Services[i].Name,
            servicePrice = serviceView.Services[i].Price,
    });
}

在服务名= serviceView.Services [I] .Name点我只有第一要素always.Why？什么是我的错？

In serviceName = serviceView.Services[i].NameI have only first element always.Why? what is my fault?

推荐答案

您需要做一些工作，帮助模型绑定进行收集。使用以下语法在您的视图，使隐藏字段。

You need to do some work to help model binder make the collection. Use the following syntax in your view to make hidden fields.

    @Html.Hidden("[" + i + "].Name", Model.Services[i].Name)
    @Html.Hidden("[" + i + "].Price", Model.Services[i].Price)

然后在您的文章操作方法，你需要接受集合

Then in your post action method you need to receive the collection

public ActionResult SelectServices(IList<Services> services)
{
   foreach(var sv in services)
    {
                    return RedirectToAction("Pool", "Rank",
                        new
                        {
                        serviceName = sv.Name,
                        servicePrice = sv.Price,
                        });
     }

}
