Windows Forms - Update CSV resource value

Question

I currently have a resource file of type CSV that I am updating via a button click.

After grabbing the new CSV from SQL server query how can I assign the new CSV as the value of my resource.

What I want (but does not work):

    Resources.services = getNewServices();

Where get new services returns a CSV file.

--UPDATE

My declaration for the file is as such in my project 'properties/resources.rex' file:

    public static string clients {
        get {
            return ResourceManager.GetString("clients", resourceCulture);
        }
    }

This was automatically generated from double clicking resources.resx and manually adding a csv file (which I keep in my project folder).
