Is it possible to put resource files (.resx) within subfolders inside App_GlobalResources?

For example:





Or, are all the .resx files placed directly inside App_GlobalResources?

If it is possible to use subfolders, how do you programmatically access resources within subfolders?

Was it helpful?


Technically, yes it is possible but there are some pitfalls. First, let me show you an example. Suppose my App_GlobalResources folder looks like so:


Each resource file has a single entry called "TestString". I added each resource file using the Visual Studio menu so it created a class for me. By default, all classes added to the App_GlobalResources folder will have the same namespace of Resource. So, if I want to use the class generator and I want Test in the namespace, I need to go into the TestSubresource.Designer.cs file and manually change the namespace. Once I do that, I can do the following:

var rootResource = Resources.TestResource.TestString;
var subResource = Resources.Test.TestSubResource.TestString;

I can also reference them using GetGlobalResourceObject:

var rootResource = GetGlobalResourceObject( "TestResource", "TestString" );
var subResource1 = GetGlobalResourceObject( "TestSubresource", "TestString" );

Notice that I still use the "TestSubresource" as the means to reference the resources in that file even though it is in a subfolder. Now, one of the catches, is that all the files must be unique across all folders in App_GlobalResources or your project will throw a runtime error. If I add a resource named "TestResource.resx" to /Test, it will throw the following runtime error:

The resource file '/App_GlobalResources/TestResource.resx' cannot be used, as it conflicts with another file with the same name.).

This is true even if I change the namespace on the new resource.

So, in conclusion, yes it is possible, but you increase the odds of getting a runtime error because of two identically named resource files in different parts of the App_GlobalResources folder structure which is allowed by the file system but not by .NET.


It's possible. At least, I managed to do it.

Within a web site I added the App_GlobalResources folder. Inside it I created another folder "MyFolder" and placed MyResource.resx file inside. Resx file contained one pair MyKey1 - MyValue1.

Using the GetResource method of the following class I successfully extracted "MyValue1" for name="MyKey1"

static class Class1 {

    static Assembly FindGlobalResAssembly() {
        foreach(Assembly asm in AppDomain.CurrentDomain.GetAssemblies()) {
                return asm;
        return null;

    public static object GetResource(string name) {
        Assembly asm = FindGlobalResAssembly();
        if(asm == null)
            return null;
        return new ResourceManager("Resources.MyResource", asm).GetObject(name);


This approach works in Medium trust also.

It seems that folders make no difference when accessing resources from code.
