剃刀：声明HTML佣工 [英] Razor: Declarative HTML helpers

问题描述

我试图写一个简单的声明的HTML帮助：

I'm trying to write a simple declarative html helper:

@helper Echo(string input) {
    @input
}

助手工作正常，如果我将它嵌入我想使用它的页面。但是，如果我将它移到一个单独的 .cshtml 文件，并将该文件中的〜/查看/助手目录，我的看法可能由于助手不在发现不能再编译。据对剃刀斯科特谷的博客文章，它应该工作。

The helper works fine if I embed it into the page I want to use it on. But if I move it to a separate .cshtml file and place that file in the ~/Views/Helpers directory, my view can't be compiled anymore because the helper is not found. According to Scott Gu's blog article on Razor it should work.

我在做什么错了？

推荐答案

的〜/查看/助手位置在ScottGu职位描述不会MVC 3 RTM工作。在时间文章写这是我们被折腾周围的设计理念，但最终我们没能实现它。

The ~/Views/Helpers location as describe in that ScottGu post will not work in MVC 3 RTM. At the time that article was written it was a design idea we were tossing around but ultimately we were not able to implement it.

把你的助手在APP_ code的作品，但具有一定的局限性影响某些MVC场景（例如：以标准的MVC没有访问 HTML 佣工）

Putting your helpers in App_Code works but has certain limitations that impact certain MVC scenarios (for example: no access to standard MVC Html. helpers)
