如何实现自定义RazorViewEngine在非标准位置查找视图？

好的，最后我选择了一种详细的方法：http :

view-
location.aspx

感谢@Adriano的回答和建议，但最终我认为这种方法更适合我的需求。下面的方法使我可以保留标准功能，但可以创建要搜索的更高优先级的新位置。

public class Travel2ViewEngine : RazorViewEngine{    protected BrandNameEnum BrandName;    private string[] _newAreaViewLocations = new string[] {        "~/Areas/{2}/%1Views/{1}/{0}.cshtml",        "~/Areas/{2}/%1Views/{1}/{0}.vbhtml",        "~/Areas/{2}/%1Views//Shared/{0}.cshtml",        "~/Areas/{2}/%1Views//Shared/{0}.vbhtml"    };    private string[] _newAreaMasterLocations = new string[] {        "~/Areas/{2}/%1Views/{1}/{0}.cshtml",        "~/Areas/{2}/%1Views/{1}/{0}.vbhtml",        "~/Areas/{2}/%1Views/Shared/{0}.cshtml",        "~/Areas/{2}/%1Views/Shared/{0}.vbhtml"    };    private string[] _newAreaPartialViewLocations = new string[] {        "~/Areas/{2}/%1Views/{1}/{0}.cshtml",        "~/Areas/{2}/%1Views/{1}/{0}.vbhtml",        "~/Areas/{2}/%1Views/Shared/{0}.cshtml",        "~/Areas/{2}/%1Views/Shared/{0}.vbhtml"    };    private string[] _newViewLocations = new string[] {        "~/%1Views/{1}/{0}.cshtml",        "~/%1Views/{1}/{0}.vbhtml",        "~/%1Views/Shared/{0}.cshtml",        "~/%1Views/Shared/{0}.vbhtml"    };    private string[] _newMasterLocations = new string[] {        "~/%1Views/{1}/{0}.cshtml",        "~/%1Views/{1}/{0}.vbhtml",        "~/%1Views/Shared/{0}.cshtml",        "~/%1Views/Shared/{0}.vbhtml"    };    private string[] _newPartialViewLocations = new string[] {        "~/%1Views/{1}/{0}.cshtml",        "~/%1Views/{1}/{0}.vbhtml",        "~/%1Views/Shared/{0}.cshtml",        "~/%1Views/Shared/{0}.vbhtml"    };    public Travel2ViewEngine()        : base()    {        Enum.TryParse<BrandNameEnum>(Travel2.WebUI.Properties.Settings.Default.BrandName, out BrandName);        AreaViewLocationFormats = AppendLocationFormats(_newAreaViewLocations, AreaViewLocationFormats);        AreaMasterLocationFormats = AppendLocationFormats(_newAreaMasterLocations, AreaMasterLocationFormats);        AreaPartialViewLocationFormats = AppendLocationFormats(_newAreaPartialViewLocations, AreaPartialViewLocationFormats);        ViewLocationFormats = AppendLocationFormats(_newViewLocations, ViewLocationFormats);        MasterLocationFormats = AppendLocationFormats(_newMasterLocations, MasterLocationFormats);        PartialViewLocationFormats = AppendLocationFormats(_newPartialViewLocations, PartialViewLocationFormats);    }    private string[] AppendLocationFormats(string[] newLocations, string[] defaultLocations)    {        List<string> viewLocations = new List<string>();        viewLocations.AddRange(newLocations);        viewLocations.AddRange(defaultLocations);        return viewLocations.ToArray();    }    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)    {        return base.CreateView(controllerContext, viewPath.Replace("%1", BrandName.ToString()), masterPath);    }    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)    {        return base.CreatePartialView(controllerContext, partialPath.Replace("%1", BrandName.ToString()));    }    protected override bool FileExists(ControllerContext controllerContext, string virtualPath)    {        return base.FileExists(controllerContext, virtualPath.Replace("%1", BrandName.ToString()));    }}

然后在Gloabal.asax中注册

protected void Application_Start(object sender, EventArgs e){    RegisterRoutes(RouteTable.Routes);    //Register our customer view engine to control T2 and TBag views and over ridding    ViewEngines.Engines.Clear();    ViewEngines.Engines.Add(new Travel2ViewEngine());}
