無法在生成的程序集（Razor Engine）中獲取應用程序實例？

Question

我真的開始在這裏失去頭髮...

我使用開源Razor engine在我的Webforms解決方案中使用Razor模板。我有一個視圖（.cshtml），我編譯。看起來是這樣的：

Sample.cshtml

@inherits RazorEngine.Templating.TemplateBase 
<h1>hoi</h1> 

我收到以下錯誤，並且對在哪裏看不知道...任何線索？

CS0103: The name 'Context' does not exist in the current context

Answer 1

該問題與我使用的基於Webforms的CMS有關。它試圖加載Razor文件作爲用戶控件，這顯然是不可能的...

Answer 2

您正在嘗試使用RazorEngine特定模板作爲視圖的基本模板類型。這將不起作用TemplateBase不會從System.Web.WebPages.WebPageBase繼承。基本上你使用的是.cshtml文件，並直接調用它，而你需要做的是這樣：

string template = File.ReadAllText(Server.MapPath("~/path/to/template.cshtml")); 
string result = Razor.Parse(template); 

你不必擔心在文件的頂部@include語句中，該TemplateBase基本類型是默認的模板基本類型，除非您想使用模型，在這種情況下默認值爲TemplateBase<T>

要從中取走的關鍵是我們沒有將RazorEngine設計爲替換MVC RazorViewEngine，也不是WebPages的構建提供者，而是提供一個簡單的模板解決方案。
