  • 学习MVC第三个参数传递(主要讲ViewModel形式)

    1: 控制器传递数据给视频有三种形式的;  ViewData(弱类型)   TempData (弱类型)  ViewModel(强类型)

    其中ViewData 只能用在本视图中的!  TempData虽然可以跨视图!但也只能一次,超过一次就会被清空!所以是一次性的Session

    ViewModel是用模型;下面是视图的顶部!若是用ViewModel就是下面这样的!但一次只能传递一个Model到视图所以要是有多个实体就要把它结合到一个实体里面;

    <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MvcAppView1.Models.BlogIndexView>" %>

    下面这个是前面两种的视图顶部

    <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/MyViewMaster.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>

    2:实例传递Model  且多个实体的

      首先是Model层

    using System.Web;

    namespace MvcAppView1.Models
    {
        public class BlogIndexView
        {
            public string Title { get; set; }
            public string Mood { get; set; }
            public IList<BlogClass> BlogClasses{ get; set; }
            public BlogInfo Blog { get; set; }
        }

        public class BlogInfo
        {
            public string Title { get; set; }
            public string Details { get; set; }
        }

        public class BlogClass
        {
            public string Title { get; set; }
            public string Explain { get; set; }
        }
    }

    再者就是控制器的代码:

    using MvcAppView1.Models;

    namespace MvcAppView1.Controllers
    {
        public class BlogController : Controller
        {
            public ActionResult Index()
            {
                BlogIndexView biv = new BlogIndexView()
                {
                    Title = "zhh 的博客",
                    Mood = "冬天就要来了……好像已经来了……"
                };
                biv.BlogClasses = new List<BlogClass>(){
                    new BlogClass(){ Title="dotNET Framework", Explain="我对.NET平台的认知与感悟"},
                    new BlogClass(){ Title="ASP.NET", Explain="ASP.NET中的一些纠结" },
                    new BlogClass(){ Title="ASP.NET MVC", Explain="ASP.NET 的新东西——MVC" },
                    new BlogClass(){ Title="个人笔记", Explain="学习中的一些感悟" }
                };
                biv.Blog = new BlogInfo() {
                    Title = "第一个.NET程序",
                    Details = "<p>其它不说,来看代码:</p><blockquote><p><code>using System;\n\n" +
                    "namespace mdibb {\n\tclass Class1 {\n\t\tstatic void Main(string[] args) {\n" +
                    "\t\t\tConsole.WriteLine(\"Hello, World\");\n\t\t}\n\t}\n" +
                    "}</code></p></blockquote><p>上面代码我向控制台中打印一个行文字“Hello World”</p>" };

                return View(biv);
            }
        }
    }

    最后是视图的代码:

    <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MvcAppView1.Models.BlogIndexView>" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
        <title><%= Model.Title %></title>
        <link href="http://www.cnblogs.com/Content/Blog.css" rel="stylesheet" type="text/css" />
    </head>
    <body>
        <div id="content">
            <div id="search">
                <form action="" method="get">
                    <p>
                        search:&nbsp;<input type="text" />&nbsp;
                        <input type="image" src="http://images.cnblogs.com/zoom.jpg" value="Submit" alt="Search" title="Search" />
                    </p>
                </form>
            </div>

            <div id="header">
                <h1><%=Model.Title %></h1>
                <p><%=Model.Mood %></p>
            </div>
            <div id="body">
                <div id="links">
                    <p>
                    <%foreach (var bc in Model.BlogClasses)
                        { %>
                        <a href="#"><%=bc.Title %></a><br/>
                        <%=bc.Explain %>
                        <br/><br/>
                    <%} %>
                    </p>
                </div>
                <div id="main">
                    <h2><%=Model.Blog.Title %></h2>
                    <%=Model.Blog.Details %>
                </div>
            </div>

            <div id="footer">
