如何添加两个模型在一个视图ASP.NET MVC [英] How to add two models in one view ASP.NET MVC

问题描述

我有两个型号。第1模型包含数据库中的每个记录。第二模型包含在记录中的最高金额。

我怎样才能获得两个模型在一个视图？我是新来Asp.NET MVC和只是想获得它的窍门。

下面是code。

型号

 命名空间CharitySite.Models
{    公共类慈善
    {
        公众诠释ID {搞定;组; }
        公共字符串显示名称{搞定;组; }
        公众的DateTime日期{搞定;组; }
        公共双倍金额{搞定;组; }
        公共双TaxBonus {搞定;组; }
        公共字符串评论{搞定;组; }
    }    公共类CharityDBContext：//的DbContext控制了数据库中的信息
    {
        公益慈善事业最高{集;得到; }
        公共DbSet＆LT;慈善与GT;捐赠{搞定;组; } //创建一个数据库捐赠
        公共CharityDBContext（）
        {
            this.Highest =新慈善（）;
        }
    }}
 

控制器

 命名空间CharitySite.Controllers
{
    公共类CharitiesController：控制器
    {
        私人CharityDBContext DB =新CharityDBContext（）;        // GET：慈善
        公众的ActionResult指数（）
        {
            VAR AllDonations =新CharityDBContext（）;
            VAR所有= db.Donations.OrderByDescending（S = GT; s.Amount）;
            如果（all.Any（））
            {
                //获取最高金额纪录
                VAR H = all.First（）;
                AllDonations.Highest.DisplayName = h.DisplayName;
                AllDonations.Highest.Amount = h.Amount;
                AllDonations.Highest.Comment = h.Comment;
            }            返回查看（AllDonations）;
        }

    ViewBag.Title =指数;}＆LT;链接HREF =@ Url.Content（〜/内容/的site.css）的rel =stylesheet属性类型=文/ CSS/＆GT;

＆所述p为H.; @ Model.Highest.DisplayName＆下; / P＆GT;＆LT; H2＆GT;最高和LT; / H＆GT;
＆所述p为H.; @ Model.Highest.Amount＆下; / P＆GT;
＆所述p为H.; @ Model.Highest.DisplayName＆下; / P＆GT;＆LT; H2＆GT;最高和LT; / H＆GT;
＆所述p为H.; @ Model.Highest.Amount＆下; / P＆GT;
＆所述p为H.; @ Model.Highest.DisplayName＆下; / P＆GT;＆LT; D​​IV CLASS =表格标题＆GT;
    @ Html.Partial（_数据库，模型）;＆LT; / DIV＆GT;
 

解决方案

您可以创建一个包含两个模型的属性自定义类就像这个例子：

 公共密封类CharitiesIndexViewModel {
     公开名单＆LT;慈善与GT;慈善{搞定;组; }
     公共最高最高{搞定;组; }
}
 

后，在您看来，您可以使用它：

  @model CharitiesIndexViewModel
 

I have two models. The 1st model contains every record in the database. The 2nd model contains the highest amount in the records.

How can I get two models in one view? I am new to Asp.NET MVC and just trying to get the hang of it.

Here is the code.

Model

namespace CharitySite.Models
{

    public class Charity
    {
        public int ID { get; set; }
        public string DisplayName { get; set; }
        public DateTime Date { get; set; }
        public Double Amount { get; set; }
        public Double TaxBonus { get; set; }
        public String Comment { get; set; }
    }

    public class CharityDBContext : DbContext //controls information in database 
    {
        public Charity Highest { set; get; }
        public DbSet<Charity> Donations { get; set; } //creates a donation database
        public CharityDBContext()
        {
            this.Highest = new Charity();


        }
    }

}

Controller

namespace CharitySite.Controllers
{
    public class CharitiesController : Controller
    {
        private CharityDBContext db = new CharityDBContext();

        // GET: Charities
        public ActionResult Index()
        {
            var AllDonations = new CharityDBContext();
            var all = db.Donations.OrderByDescending(s => s.Amount);
            if (all.Any())
            {
                //Get the highest amount record
                var h = all.First();
                AllDonations.Highest.DisplayName = h.DisplayName;
                AllDonations.Highest.Amount = h.Amount;
                AllDonations.Highest.Comment = h.Comment;
            }

            return View(AllDonations);
        }

View

@model IEnumerable<CharitySite.Models.Charity>
@model CharitySite.Models.CharityDBContext



@{
    ViewBag.Title = "Index";

}

<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/bootstrap.css")" rel="stylesheet" type="text/css" />
<div id="header">

    <h1>Syria</h1>

</div>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<h2>Highest</h2>
<p>@Model.Highest.Amount</p>
<p>@Model.Highest.DisplayName</p>

<div class="table-title">
    @Html.Partial("_Database", Model);

</div>

解决方案

You can create a custom class with two model's properties like in this example:

public sealed class CharitiesIndexViewModel {
     public List<Charity> Charities { get; set; }
     public Highest Highest { get; set; }
}

After, in your View, you can use it:

@model CharitiesIndexViewModel
