Question

我想在我的网站上添加使用完全不同视图的主题。我希望在我的项目中看到它们：

Views/Theme1/...
Views/Theme2/...

而不是默认

Views/...

因为我需要一种简单的方法来切换它们。

所以问题是：如何让ViewEngine在所提到的特定位置查找视图，例如在web.config中？

加

用Archil解决了这个基本问题：

public class ThemedRazorViewEngine : RazorViewEngine
{
    public ThemedRazorViewEngine(string themeName)
    {
        MasterLocationFormats = new string[] { "~/Views/" + themeName + "/Shared/{0}.cshtml" };
        PartialViewLocationFormats = new string[] { "~/Views/" + themeName + "/{1}/{0}.cshtml" };
        ViewLocationFormats = new string[] { "~/Views/" + themeName + "/{1}/{0}.cshtml" };
    }
}

一切都很好，但“右键点击 - ＆gt;转到查看”不再起作用（副作用，没什么大不了的。）

现在我提出了另一个问题：在网站上我们有管理面板，应该是主题独立的。我该如何解决这个问题？有类似的东西：

Views/Admin/...
Views/Theme1/...
Views/Theme2/...

Answer 1

如何让ViewEngine在特定位置查找视图提及。

您需要在View方法中提供路径：

return View("~/Views/Theme1/Index");
return View("~/Views/Theme2/Index");

对于web.config示例：

var themeFromWebConfig = GetThemeFromWebConfig();
var viewName = "~/Views/" + themeFromWebConfig + "/Index";
return View(viewName);

web.config中最简单的主题值解决方案是创建自定义ViewEngine并仅覆盖视图搜索位置。这样你就不必在Controller中改变任何东西（例子只使用c＃only视图引擎的cshtml文件，如果你想使用visual basic视图，你必须添加vbhtml扩展名）

public class ThemedRazorViewEngine : RazorViewEngine
{
    public ThemedRazorViewEngine(string themeName)
    {
        AreaMasterLocationFormats = new string[] { "~/Areas/{2}/Views/ " + themeName + "/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/" + themeName + "/{0}.cshtml" };

        //and same for all of below
        AreaPartialViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.cshtml" };
        AreaViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.cshtml" };
        FileExtensions = new string[] { "cshtml" };
        MasterLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" };
        PartialViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" };
        ViewLocationFormats = new string[] { "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" };
    }
}

注册视图引擎

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new ThemedRazorViewEngine(ConfigurationManager.AppSettings["currentTheme"]));

asp.net mvc 3，主题（不同视图）
