Question

我是ASP.Net MVC的新手。我正在尝试从查询字符串的ID中获取硬编码数据。

我正在开发一个简单的ASP.Net Web项目。有些客户数据是经过硬编码的。通过单击超链接进行重定向时，我需要在另一个页面中检索和显示数据。

// CustomerController

public ActionResult Details(int id) {


            var viewModel = new RandomMovieViewModel {
                CustomerID = id,
                CustomerName = "Test"
            };
            return View(viewModel);

        }

// RandomViewModel类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Vidly.Models;

namespace Vidly.ViewModels
{
    public class RandomMovieViewModel
    {
        public Movie Movie { get; set; }
        public List<Customer> Customers { get; set; }

        public List<Movie> Movies { get; set; }

        public int CustomerID { get; set; }

        public string CustomerName { get; set; }
    }
}

// Index.cshtml

@model Vidly.ViewModels.RandomMovieViewModel
@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Customers</h2>
@if (Model.Customers.Count == 0)
{
    <text>We don't have any customers yet.</text>
}
else
{

    <ul class="list-group">
        <li class="list-group-item d-flex justify-content-between align-items-center">
            <b>Customer</b>

        </li>

        @foreach (var customer in Model.Customers)
        {
            <li class="list-group-item d-flex justify-content-between align-items-center">
                <a href="../Customers/Details/@customer.Id">

                    @customer.Name
                </a>

            </li>
        }

    </ul>
}

Details.cshtml

@model Vidly.ViewModels.RandomMovieViewModel
@{
    ViewBag.Title = "Details";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>@Model.CustomerName</h2>

单击超链接时，应显示选定的客户名称。

Answer 1

@foreach (var customer in Model.Customers)
    {
        <li class="list-group-item d-flex justify-content-between align-items-center">
            <a href="../Customers/Details/@customer.Id">

                @customer.Name
            </a>

        </li>
    }

要从查询字符串的视图中获取ID值，您需要使用

来增强代码

 <a href="../Customers/Details?id=@customer.Id">

从给定的ID获取数据
