Using ResourceManager


I'm trying to use the ResourceManager in a C# class, but don't know what to substitute for the basename when creating a new instance of the ResourceManager class.

I have a separate project that contains the resource files which is referenced by my project above named as the following:

  • Resources.resx

If I have a code snippet as follows, what should I substitute for the basename when I want to use the English or Spanish version of the resources?

ResourceManager RM = new ResourceManager(basename,Assembly.GetExecutingAssembly());

I tried the approach suggested by Tom, but am getting the infamous error

Could not find any resources appropriate for the specified culture or the neutral culture.

My solution has two projects where project YeagerTech is a web application and project YeagerTechResources contains all the resources. Project YeagerTech has a reference to YeagerTechResources.

I have the following syntax when creating my Resource Manager:

ResourceManager RM = new ResourceManager("YeagerTechResources.Resources",

Obviously, it's incorrect.

The resource files in the YeagerTechResources project have their BuildAction set to Embedded Resource.

The name of my resource files are: Resources.resx and

If someone can simply tell me the exact syntax to use based on my project and resource file names when instantiating the resource manager, I would greatly appreciate it...

I've done everything I can think of to resolve this and can't....

This is my last attempt to resolve it here...

ResourceManager RM = new ResourceManager("YeagerTechResources.Resources", Assembly.GetExecutingAssembly());


I am getting the following error after executing the code above:

Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "YeagerTechResources.Resources.resources" was correctly embedded or linked into assembly "YeagerTech" at compile time, or that all the satellite assemblies required are loadable and fully signed.

I am able to use the resources in the HTML markup with absolutely no issues, but when coming to the C# code in the Controller, I keep on getting the above error.

Any help for the exact syntax I need based on my projects would be greatly appreciated.

There's surprisingly simple way of reading resource by string:


It's clean and elegant solution for reading resources by keys where "dot notation" cannot be used (for instance when resource key is persisted in the database).

The quick and dirty way to check what string you need it to look at the generated .resources files.

Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)

Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.

For example in my obj/Bin directory I have the file:


If the resource files are in the same Class library/Application I would use the following C#

ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());

However, as it sounds like you are using the resources file from a separate Class library/Application you probably want

Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM =  new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);
