EditorFor 布尔类型的模板

Question

当使用带有值类型模板的EditorFor() 时，我们如何访问模型的属性名称，例如下面的bool 类型？

似乎 MVC 以某种方式提取了属性名称，因为它正确地呈现了具有正确属性名称的复选框（或文本框，如果使用），但是 MVC 从哪里得到它？

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<bool>" %>
 <fieldset>
        <legend>insert boolean property name here or the value of DisplayName attribute??</legend>
            <div class="clear">
                <p>
                    <%: Html.CheckBox("", Model) %>
                    <span>insert boolean property name here or the value of DisplayName attribute??</span>
                </p>
            </div>
    </fieldset>

使用 MVC3、Jquery 1.7 和 CSS3 的 EditorTemplate 的布尔类型示例

EditorTemplates Boolean.cshtml

@model bool
@{
    string propertyName = Html.ViewData.ModelMetadata.PropertyName;
}
<div class="field switch">
    @if (@Model == true)
    {
        <label class="cb-enable selected">
            <span>Yes</span></label>
        <label class="cb-disable">
            <span>No</span></label>
        <input type="checkbox" id="@propertyName" class="checkbox" name="@propertyName" value="true" checked=checked />
    }
    else
    {
        <label class="cb-enable">
            <span>Yes</span></label>
        <label class="cb-disable selected">
            <span>No</span></label>
        <input type="checkbox" id="@propertyName" class="checkbox" name="@propertyName" value="false"   />
    }
</div>
<script>
    $(document).ready(function () {
        $(".cb-enable").click(function () {
            var parent = $(this).parents('.switch');
            $('.cb-disable', parent).removeClass('selected');
            $(this).addClass('selected');
            $('.checkbox', parent).attr('checked', true);
            $('.checkbox', parent).attr('value', true);
        });
        $(".cb-disable").click(function () {
            var parent = $(this).parents('.switch');
            $('.cb-enable', parent).removeClass('selected');
            $(this).addClass('selected');
            $('.checkbox', parent).attr('checked', false);
            $('.checkbox', parent).attr('value', false);
        });
    });
</script>

CSS

    .cb-enable, .cb-disable, .cb-enable span, .cb-disable span
    {
      display: block; float: left;
    }
    .cb-enable {

Answer 2

<%: ViewData.ModelMetadata.PropertyName %>

或：

<%: ViewData.ModelMetadata.DisplayName %>

更新：

资源本地化显示属性示例：

public class LocalizedDisplayNameAttribute : DisplayNameAttribute
{
    public LocalizedDisplayNameAttribute(string name)
        : base(GetValueFromResource(name))
    { }

    private static string GetValueFromResource(string name)
    {
        // TODO: fetch the display name from wherever you want
        throw new NotImplementedException();
    }
}
