Resource files not found from .resx file

Question

I have added some existing configuration files in a Resource file (.resx). I have written the following code to get the files from resource file and write those files in a destination folder configured in Settings.settings file.

using (var resourceStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("Fs.ExtendedImporter.Application.Configuration.SampleConfigFiles.ExampleFiles.resx"))
{
    if (resourceStream != null)
    {
        using (var resourceReader = new ResourceReader(resourceStream))
        {
            foreach (DictionaryEntry resource in resourceReader)
            {
                string resourceName = (string)resource.Key;
                byte[] resourceData = (byte[])resource.Value;
                string destinationFile = Path.Combine(Settings.Default.ApplicationConfiguration, resourceName);

                if (!File.Exists(destinationFile))
                {
                    File.WriteAllBytes(destinationFile, resourceData);
                }
            }
        }
    }
    else
    {
        Logger.Log.Error("Resource file not found.");
    }
}

But resourceSteam variable is returning null in this code.

I have checked the resource(.resx) file property and got ensured that the Build action is set to Embedded Resource.

Also the namespace is correct in GetManifestResourceStream() method.

What could be the problem? I appreciate your valuable help.

Finally, I found ResourceManager as alternative and it worked for me-

// Create a ResourceManager for the resource file
var resourceManager = new ResourceManager(
    "Fs.ExtendedImporter.Application.Configuration.SampleConfigFiles.ExampleFiles",
    Assembly.GetExecutingAssembly());

// Get all resource names in the resource file
var resourceSet = resourceManager.GetResourceSet(System.Globalization.CultureInfo.CurrentCulture, true, true);

foreach (var resource in resourceSet)
{
    var resourceEntry = (System.Collections.DictionaryEntry)resource;
    string resourceName = resourceEntry.Key.ToString();
    object resourceValue = resourceEntry.Value;
    string destinationFile = Path.Combine(Settings.Default.ApplicationConfiguration, resourceName + ".xml");
    // Handle string resources
    if (resourceValue is string stringValue)
    {
        if (!File.Exists(destinationFile))
        {
            File.WriteAllText(destinationFile, stringValue);
        }
    }
    // Handle binary resources (byte arrays)
    else if (resourceValue is byte[] binaryValue)
    {
        if (!File.Exists(destinationFile))
        {
            File.WriteAllBytes(destinationFile, binaryValue);
        }
    }
}
