1、使用ViewBag

 1         #region 0.2 Action方法 + ActionResult Index2()
 2         /// <summary>
 3         /// Action方法
 4         /// </summary>
 5         /// <returns></returns>
 6         public ActionResult Index2()
 7         {
 8             System.Text.StringBuilder sbhtml = new System.Text.StringBuilder();
 9             List<Models.dog> list = InitData();
10             list.ForEach(d =>
11             {
12                 sbhtml.AppendLine("<div>" + d.ToString() + "</div>");
13             });
14 
15             ViewBag.HtmlStr = sbhtml.ToString();
16 
17             return View();
18         } 
19         #endregion
View Code

 

Index2.cshtml

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
        @Html.Raw(ViewBag.HtmlStr)
 
</body>
</html>
View Code


2、使用ViewData

 1         #region 0.3 查询文章列表 + ActionResult Index3()
 2         /// <summary>
 3         /// 查询 文章 列表
 4         /// </summary>
 5         /// <returns></returns>
 6         OumindBlogEntities db = new OumindBlogEntities();
 7 
 8         public ActionResult Index3()
 9         {
10             List<Models.BlogArticle> list = (from d in db.BlogArticles where d.AIsDel == false select d).ToList();
11 
12             ViewData["DataList"] = list;
13             return View();
14         } 
15         #endregion
View Code

 

Index3.cshtml

@using MvcLewisTest.Models;
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <style type="text/css">
       #tbList
       {
           border:1px solid #0094ff;
           border-collapse:collapse;
           margin:10px auto;
           width:800px;
       }
       #tbList th,td
       {
           border:1px solid #0094ff;
           padding:10px;
           }
    </style>
    <script type="text/javascript">
       function del(Aid) {
            if (confirm("确定要删除吗?"))
                window.location = "/Home/Del/" + Aid; 
        }
    </script>
</head>
<body>
    <table id="tbList">
       <tr>              
          <th>id</th>
          <th>标题</th>
          <th>分类</th>
          <th>状态</th>
          <th>时间</th>
          <th>操作</th>
       </tr>
    @foreach (BlogArticle a in ViewData["DataList"] as List<BlogArticle>) 
    {
        <tr>              
          <td>@a.AId</td>
          <td>@a.ATitle</td>
          <td>@a.BlogArticleCate.Name</td>
          <td>@a.Enumeration.e_cname</td>
          <td>@a.AAddtime</td>
          <td>
             <a href="javascript:del(@a.AId)">删</a>
             <a href="/Home/Modify/@a.AId">改</a>
          </td>
       </tr>
    }
   </table>
</body>
</html>
View Code


3、使用Control器的 return View()

 1         #region 0.5 显示要修改数据(根据Id) +  ActionResult Modify(int id)
 2         [HttpGet]
 3         /// <summary>
 4         /// 显示要修改的数据
 5         /// </summary>
 6         /// <param name="id"></param>
 7         /// <returns></returns>
 8         public ActionResult Modify(int id)
 9         {
10             //1.根据id查询出要修改的对象
11             BlogArticle art = (from a in db.BlogArticles where a.AId == id select a).FirstOrDefault();
12             //2.生产文章分类下来框
13             IEnumerable<SelectListItem> listItem = (from c in db.BlogArticleCates
14                                          where c.IsDel == false select c).ToList()
15                                          .Select(c => new SelectListItem { Value = c.Id.ToString(), Text = c.Name });
16             //3.将生成的文章分类 下拉框集合 设置给ViewBag
17             ViewBag.CateList = listItem;
18             //4.加载视图,使用View构造函数,将数据传给视图上Model属性
19             return View(art);
20         } 
21         #endregion
