c# - 列表模型 Razor View

Question

我有一个应用程序 asp.net mvc 。在 Controller 中我有这个:

 public ActionResult Index()
        {
            Upload.Models.ClientModels model1 = new Models.ClientModels();
            ArrayList client = model1.Client_List();

            Upload.Models.AkeoModels model2 = new Models.AkeoModels();
            ArrayList akeo = model2.Akeo_List();


            ArrayList model = new ArrayList();
            model.Add(client);
            model.Add(akeo);
            return View(model);




        }

我将两个串联列表作为模型传递给 View 索引:

@{
    ViewBag.Title = "Bienvenue";
    int i = 0;
}

<hgroup class="title">
    <h1 style="color:darkcyan">Liste des clients</h1>
</hgroup>

<section >

<form>


<table style="margin-top: 50px;">
    <tr ><td ></td>
        <td ><center><b>Login</b></center></td>
        <td><center><b>Email</b></center></td>
        <td><center><b>Password</b></center></td>
        <td><center><b>Name</b></center></td>

    </tr>
    @{
        Upload.Models.ClientModels client = null;
        int j = 0;
        while( j != -1)
    {
        try
        {
            client = Model[j];
          <tr>
        <td width=10px>
            @if (i == 0)
            {
      <input type="radio" 
        name="color" checked >
            }
            else
            {<input type="radio"  name="color" >
            }      
    </td>
    <td>
      <a type="text" 
        name="color" >@client.Login</a>
    </td>

    <td>
      <a type="text" 
        name="color" >@client.Mail</a>
    </td>
      <td>
      <a type="text" 
        name="color" >@client.Password</a>
    </td>
      <td>
      <a type="text" 
        name="color" >@client.Name</a>
    </td>
  </tr>
            i++;
            j++;
        }
        catch {j = -1;}
    }
        i = 0;
    }

问题是:列表的值没有显示。在 View Index 中，仅显示表格下方的标签和按钮，但不显示模型的内容。我正在调试程序，模型不是空的，它包含两个元素。

1. View 中的错误在哪里？
2. 我该如何解决？

Answer 1

你不应该使用 ArrayList。您应该创建一个包含来自两个模型的属性的自定义类型。

例如:

public class CustomModel 
{
   public int PropertyOne { get; set; }
   public string PropertyTwo { get; set; }
}

或者您可以:

public class CustomModel2 
{
   public List<Models.ClientModels> ClientModels { get; set; }
   public List<Models.Akeo_List> AkeoModels { get; set; }
}

Controller :

public ActionResult Index() 
{
  var model = new List<CustomModel>();
  model.Add(new CustomModel() { });
  return View(model);
}

查看

@Model List<CustomModel>

foreach(var cm in @Model) {
     cm.PropertyOne
}

如果您使用的是 CustomModel2，您可以通过以下方式遍历所有客户端:

   foreach (var client in @Model.ClientModels) {
       @client.ClientName
   }
