ASP.NET MVC HtmlHelper类的辅助和扩展方法 不指定

微软官方:http://technet.microsoft.com/zh-cn/library/dd492619
HtmlHelper类的辅助和扩展方法:

(1)ActionLink  生成一个特定的控制器行为连接
            <%=Html.ActionLink("Edit", "Edit", "Book", new { id = Model.ID }, new { @class = "BookDetail"})%>
            具体说明:
            Edit,为linkText,具体而言就是显示的字符串
            Edit,对应为ActionName;
          Book,为Controller;
          new { id = Model.ID },为生成元素的id定义;
          new { @class = “BookDetail” },则为元素添加了tag要素
(2)AntiForgeryToken 生成一个隐藏的表单字段,可与ValidateAntiForgeryToken属性一起使用以确保Request没有被修改
            具体说明:
                 如果你要保护你的应用程序的多个形式的相互独立,AntiForgeryToken 将生成不同的防伪标志
                  <%= Html.AntiForgeryToken("someArbitraryString") %>
                  [ValidateAntiForgeryToken(Salt="someArbitraryString")]
                 public ViewResult SubmitUpdate()
                 {
                           // ... etc
                  }

(3)AttributeEncode 数据属性编码 :提供了HtmlAttributeEncode功能
                具体说明:
                 <%= Html.AttributeEncode(Url.Action("Login")) %>

(4)DropDownList   基于一对键值对生成DropDownList(绑定数据:http://blog.csdn.net/yh_bxhl/article/details/6107500)
               具体说明:
             Html.DropDownList(    string name,    IEnumerable<SelectListItem> selectList,    string optionLabel,    object htmlAttributes)
             name:选择元素的名称,绑定到元素视图的模型属性
             selectList:选项列表,
             optionLabel:类似与“Select …”   可选的默认的标签
             htmlAttributes:可添加的属性
             使用方法          
代码
        List<SelectListItem> items = new List<SelectListItem>();
         items.Add( new SelectListItem { Text = "Swimming", Value = "1" });
         items.Add(new SelectListItem { Text = "Cycling", Value = "2", Selected = true });
         items.Add(new SelectListItem { Text = "Running", Value = "3" });
        ViewData["ListItems"] = items;

           <%= Html.DropDownList("ListItems") %>
(5)Encode 编码字符串,以防跨站脚本攻击  
   使用方法
            < %=Html.Encode("< script src=/"j . JS/">< div background='javascript:alert('');'/>")%>
    编码结果
             &lt;script src=&quot;j . JS&quot;&gt;&lt;/script&gt;&lt;div background='javascript:alert('');'/&gt;

(6)Hidden 生成表单隐藏字段
            <%= Html.Hidden("SearchType", 1) %>
            前台源代码:
             <input id="SearchType" name="SearchType" type="hidden" value="1" />
(7)ListBox  基于列键值对生成下拉框
          使用方法:  
代码
<%= Html.ListBox(

                                             Text = "Option 1",
                                             Value = "opt1"
                                     },
                                  new SelectListItem
                                     {
                                             Text = "Option 2",
                                             Value = "opt2"
                                     },
                                  new SelectListItem
                                     {
                                             Text = "Option 3",
                                             Value = "opt3"
                                     }
                },
               "Choose an option"  
             ) %>

             前台源代码:
                <select Length="16" id="optionsList" multiple="multiple" name="optionsList">
                      <option value="opt1">Option 1</option>
                      <option value="opt2">Option 2</option>
                      <option value="opt3">Option 3</option>
