MVC3 Razor 模板 - EditorForModel

Question

所以，我正在关注 本文自定义 Html.EditorForModel 模板。让它工作 - 很好。

我尝试将其转换为 Razor (Object.cshtml) 并得到：

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. 
Compiler Error Message: CS0115: 'ASP._Page_Views_Shared_EditorTemplates_Object_cshtml.Execute()': no suitable method found to override

Source Error:


Line 44:         }
Line 45:         
Line 46:         public override void Execute() {
Line 47: 
Line 48: 

代码

@inherits System.Web.Mvc.ViewUserControl
@{  var count = 0; }
@if (ViewData.TemplateInfo.TemplateDepth > 1) { 
  @ViewData.ModelMetadata.SimpleDisplayText
} 
else { 
  <table class="form">
    <tr>
    @foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm))) {
      if(prop.HideSurroundingHtml) {
        @Html.Editor(prop.PropertyName) 
      } 
      else { 
        if(count == 2) {
          count = 0;
          @:</tr><tr>
        } 
        else {
          count++;
        }
        <td>hi
          <div class="editor-label" style="text-align: right;">
            @prop.IsRequired ? "*" : "" 
            @Html.Label(prop.PropertyName) 
          </div>
        </td>
        <td>
          <div class="editor-field">
            @Html.Editor(prop.PropertyName) 
            @Html.ValidationMessage(prop.PropertyName, "*") 
          </div>
        </td>
      } 
    } 
    </tr>
  </table>
} 

这是我无法猜测的

。 “有趣的是”当模板被称为“_Object.cshtml”时， @Html.EditorForModel("~/Views/Shared/EditorTemplates/_Object.cshtml") 被完全忽略并使用默认模板，所以知道为什么必须被称为“对象”将是一个很好的了解。

尝试删除第一行（@inherits 内容）：

@{ var count = 0; }
@if (ViewData.TemplateInfo.TemplateDepth > 1) { 
  @ViewData.ModelMetadata.SimpleDisplayText
} 
else { 
  <table class="form">
    <tr>
    @foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm))) {
      if(prop.HideSurroundingHtml) {
        @Html.Editor(prop.PropertyName) 
      } 
      else { 
        if(count == 2) {
          count = 0;
          @:</tr><tr>
        } 
        else {
          count++;
        }
        <td>hi
          <div class="editor-label" style="text-align: right;">
            @if (prop.IsRequired)
            {
                @:*   
            }
            @Html.Label(prop.PropertyName) 
          </div>
        </td>
        <td>
          <div class="editor-field">
            @Html.Editor(prop.PropertyName) 
            @Html.ValidationMessage(prop.PropertyName, "*") 
          </div>
        </td>
      } 
    } 
    </tr>
  </table>
} 

另请注意我重写 @prop.IsRequired 测试的方式。
