c# - Specifying Area to search for Views in -

i have mvc4 app uses 1 area (in addition normal location). working fine routing, have need code in 'root' location find partial view inside area.

the relevant parts of solution's files are:

/areas /areas/admin /areas/admin/views /areas/admin/views/shared/_adminpartialview.cshtml /views /views/shared/_rootpartialview.cshtml 

and failing code is:

var viewengine = new razorviewengine(); var ccontext = new controllercontext(context, new routedata(), new emptycontroller());  // works: var rootview = viewengine.findpartialview(ccontext, "_rootpartialview", false); if (rootview == null) { throw new exception("root view not found"); }  // throws error: var adminview = viewengine.findpartialview(ccontext, "_adminpartialview", false); if (adminview == null) { throw new exception("admin view not found"); } 

(context above coming indirectly httpcontext.current)

... makes sense, without area specified admin area shouldn't searched... when change viewengine above = new adminrazorviewengine();, defined as:

public class adminrazorviewengine : razorviewengine {     public adminrazorviewengine() {         var viewlocations = new [] {             "~/areas/admin/views/{1}/{0}.cshtml",             "~/areas/admin/views/shared/{0}.cshtml"         };         base.viewlocationformats = viewlocations.concat(base.viewlocationformats).toarray();     } }    

i still same results.

if copy _adminpartialview.cshtml /views/shared/ both views found correctly, using either view engine.

i've tried creating actual routedata object, specifying area on it, , using when constructing controllercontext:

var routedata = new routedata(); routedate.values.add("area", "admin"); // ... var ccontext = new controllercontext(context, routedata, new emptycontroller()); 

with no change in behavior.

how can explicitly specify area view engine search in?

try setting areaviewlocationformats instead of viewlocationformats

here code ilspy razorviewengine

    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"         };     }
