RazorEngine - 如何使用我自己的HTML助手？

Question

我已经在RazorEngine模板如下：

@using WAND.Helpers 
@model Tour.Entities.Accommodation 

<p> 
    You can view your WAND accommodation home page by @Html.HomepageActionLink("Accommodation","clicking here",@Model.AccommodationId) 
</p> 

的HomePageActionLink是一个帮助我写的，看起来在某种程度上，这样的：

public static MvcHtmlString HomepageActionLink(this HtmlHelper helper, string serviceProviderType, string linkText, int idValue) 
    { 
     ... 

     return new MvcHtmlString(link); 
    } 

的问题是，当我运行此，我收到一条错误消息：

More details about the error: - error: (64, 60) The name 'Html' does not exist in the current context 

有没有办法让这个工作？

您可以用具有Html实现的类覆盖BaseTemplateType。 Like

var config = new TemplateServiceConfiguration(); 
     // MvcHtmlStringFactory code from 
     // http://stackoverflow.com/questions/19431365/razorengine-html-helpers-work-but-escape-the-html 
     config.EncodedStringFactory = new MvcHtmlStringFactory(); 

     // HtmlTemplateBase code from 
     // http://stackoverflow.com/questions/8561164/razorengine-issues-with-html 
     config.BaseTemplateType = typeof(HtmlTemplateBase<>); 
     var service = RazorEngineService.Create(config); 

     var Colmodel ="@Html.BeginForm(\"UploadDocument\", \"Detail\", new{a=1,b=2})"; 

     string res = service.RunCompile(Colmodel, Colmodel, 
      model.GetType(), model);
