Question

我正在使用asp.net mvc开发一个Web应用程序。我有一组扬声器，我想在其中显示相应的扬声器名称。我已经使用数组来检索数据。但是它没有使用其他参数。我的观点是：

@model  List<CTCFremont.View_Details> 

@{
    ViewBag.Title = "Leaders";
}
<style>
    .img-circle {
        border-radius: 50%;
    }
</style>


<h2>Leaders</h2>
<div class ="container">
    <table>

    @{
        int j = 0;
        for (int i = 0; i < Model.Count(); i+= 1)
        {
            j = i;

            <tr>
                @while (j <= i && j < Model.Count())
                {         
                    <td>
                        <img   src="data:image/png;base64,@Convert.ToBase64String(Model[j].Picture,0,Model[j].Picture.Length)" width="250" height="250" class="img-circle" />               
                    </td> 
                    j++;
                }
            </tr>  
            <tr> 
                @while (j <= i && j < Model.Count())
                {                                 
                    <td>              
                        <b>@Html.DisplayFor(modelItem => Model[j].Name)</b>                                              
                    </td> 
                    j++;
                }               
            </tr> 
            <tr>  
                @while (j <= i && j < Model.Count())
                {                                  
                    <td>                
                        <b>@Html.DisplayFor(modelItem => Model[j].Position)</b>
                    </td> 
                    j++;
                }                   
            </tr>

            //foreach (var item in Model) {                    
            //   }
        }
    }
    </table>
</div>

我的模特是：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace CTCFremont.Controllers
{
    public class View_DetailsController : Controller
    {
        //
        // GET: /View_Details/

        public ActionResult Gallery()
        {
            List<View_Details> all = new List<View_Details>();

            // Here MyDatabaseEntities is our datacontext
            using (CTCFremontEntities dc = new CTCFremontEntities())
            {
                all = dc.View_Details.ToList();
            }
            return View(all.ToList());
        }
        public ActionResult Index()
        {
            return View();
        }

    }
}

我认为你已经多次使用模型循环复杂化了。这是你想要做的吗？

foreach (var item in Model)
{
    <tr>    
        <td>
            <img src="data:image/png;base64,@Convert.ToBase64String(item.Picture,0,item.Picture.Length)" width="250" height="250" class="img-circle" />               
        </td> 
    </tr>  
    <tr> 
        <td>
            <b>@item.Name</b>
        </td> 
    </tr> 
    <tr>  
        <td>                
            <b>@item.Position</b>
        </td> 
    </tr>
}
