在ASP.NET MVC中定义更多“共享”文件夹

  您可以编写一个custom view engine，您可以在其中指定ASP.NET MVC将查找视图的其他文件夹 .

  这里的想法是编写一个派生自 RazorViewEngine 的类，并在其构造函数中设置各种属性，例如：

  • AreaViewLocationFormats

  • AreaMasterLocationFormats

  • AreaPartialViewLocationFormats

  • ViewLocationFormats

  • MasterLocationFormats

  • PartialViewLocationFormats

  以下是您可以随意覆盖的默认值：

  public RazorViewEngine(IViewPageActivator viewPageActivator) : base(viewPageActivator)
  {
      base.AreaViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };
      base.AreaMasterLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };
      base.AreaPartialViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };
      base.ViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml", "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml" };
      base.MasterLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml", "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml" };
      base.PartialViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/{1}/{0}.vbhtml", "~/Views/Shared/{0}.cshtml", "~/Views/Shared/{0}.vbhtml" };
      base.FileExtensions = new string[] { "cshtml", "vbhtml" };
  }
  

  然后只需在 Application_Start 中注册您的自定义视图引擎：

  ViewEngines.Engines.Clear();
  ViewEngines.Engines.Add(new MyRazorViewEngine());
  

  在这个例子中，我在注册自定义引擎之前删除了所有其他默认视图引擎（WebForms和Razor） .

  如果您想知道如何从Darin上面的答案开始，这就是我实现它的方式 . 所有的功劳都归功于达林和欧文 .

  我基本上想将所有部分视图放在 Views/Controller/Shared 文件夹下 . 所以我只替换了"RazorViewEngine"的"PartialViewLocationFormats"属性 . 添加了“ ~/Views/{1}/Shared/{0}.cshtml ”作为列表中的第一个元素，以便ViewEngine首先查看 "Views/Controller/Shared “文件夹 .

  然后，正如Darin在global.asax中解释的那样，清除现有的视图引擎并添加新的视图引擎 .

  ViewEngines.Engines.Add(new CustomRazorViewEngine());
  

  希望这有助于某人 .

  public class CustomRazorViewEngine : RazorViewEngine
      {
          public CustomRazorViewEngine()
          {
              var newLocationFormat = new[]
                                      {
                                          "~/Views/{1}/Shared/{0}.cshtml",
                                          "~/Views/{1}/{0}.cshtml", 
                                          "~/Views/{1}/{0}.vbhtml", 
                                          "~/Views/Shared/{0}.cshtml", 
                                          "~/Views/Shared/{0}.vbhtml"
                                      };
  
              PartialViewLocationFormats = newLocationFormat;
          }
  
      }
