如何在 asp.net mvc 中更改搜索 viewLocation 的顺序？

Question

在我的项目中，我有一个名为 Common 的文件夹，我想 Asp.net Mvc 搜索 Common 文件夹以查找 Views，而不是共享文件夹。

也就是说，搜索位置视图的顺序如下：

~/Views/Home/Index.cshtml
~/Views/Home/Index.vbhtml
~/Views/Common/Index.cshtml
~/Views/Common/Index.vbhtml

一个简单的解决方案。

在 Application_Start 事件上通过 ViewEngines.Engines 集合获取 RazorViewEngine 并更新其 ViewLocationFormats

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    var razorEngine = ViewEngines.Engines.OfType<RazorViewEngine>().First();
    razorEngine.ViewLocationFormats = new string[]
        {
            "~/Views/Home/Index.cshtml",
            "~/Views/Home/Index.vbhtml",
            "~/Views/Common/{0}.cshtml",
            "~/Views/Common/{0}.vbhtml"
        };
}

如果只想改变顺序，可以使用Concat方法组合默认位置和新位置。

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    var razorEngine = ViewEngines.Engines.OfType<RazorViewEngine>().First();

    var newLocationPath = new string[]
    {
        "~/Views/Home/Index.cshtml",
        "~/Views/Home/Index.vbhtml",
        "~/Views/Common/{0}.cshtml",
        "~/Views/Common/{0}.vbhtml"
    }.Concat(razorEngine.ViewLocationFormats);

    razorEngine.ViewLocationFormats = newLocationPath.ToArray();
}

您可以创建自定义 class 继承 RazorViewEngine

usin System.Web.Mvc
namespace Views.Infrastructure{
public class CustomrazorViewEngine : RazorViewEngin{
    public CustomrazorViewEngine(){
        ViewLocationFormats=new string[]{
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Common/{0}.cshtml"
            };
        }
    }
}

并在 Global.asax

proteced void Application_Start()
{
    AreaRegisteration.registerAllArea();
    ViewEngines.Engines.Clear();
    ViewEngines.Engines.Add(new CustomrazorViewEngine());
    RoutConfig.registerRoutes(RouteTable.Routes);
}

我建议这样做是为了防止其他引入的 Viewengines 的冲突：

ViewEngines.Engines.Clear();
