MVC 3 Razor _ViewStart中的公共变量 [英] Public variables in MVC 3 Razor _ViewStart

问题描述

我正在MVC 3附带的新Razor引擎上构建一个站点(并且喜欢新语法！).但是，我对将其与公共属性/常量一起使用一无所知.我知道，使用WebForms，我们可以在代码后面添加一个公共属性:

I'm building a site on the new Razor engine that comes with MVC 3 (and loving the new syntax!). However, I am at a loss about using public properties / constants with it. I know that with WebForms we could add a public property in code behind:

public string ImageFolder { get; set; }

我想在一个全局视图中定义重要的变量，我的视图可以从CSS文件和图像的路径开始:

I would like to define important variables in one global place that my views can access, starting with paths to CSS files and images:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
    var ContentFolder = "~/Content";
    var CssFolder = ContentFolder + "/Stylesheets";
    var ImageFolder = ContentFolder + "/Images";
}

我尝试将上面的代码块放入_Layout以及_ViewStart内.但是，从子视图访问它们失败了.我想在上面的代码块中定义一个公共属性，但是它不能编译.

I have tried putting the above code block in _Layout, as well as inside _ViewStart. However, accessing them from child views fails miserably. I thought of defining a public property in the above code block but it doesn't compile.

• 据我所知，没有人在Razor后面使用任何代码.
• 我想我应该能够从默认视图继承并在那里定义我的属性(如但是我强烈希望应该有一种更简单的方法来做这么简单的事情?

  But I'm strongly hoping that there should be an easier way to do something so simple?

  推荐答案

  您可以创建一个文件夹"App_Code"并创建一个文件"GlobalVal.cshtml". 下面是文件中的示例代码:

  Your can create a folder "App_Code" and create a file "GlobalVal.cshtml". bellow is a sample code in the file:

  @functions{
      public static readonly string __siteHome = "http://www.example.com";
      public static readonly string __siteResource = "http://resource.example.com";
  }
  

  下面是使用它的示例:

  <a href="@GlobalVal.__siteHome/home/index">@GlobalVal.__siteHome</a>
