Any Umbraco wizards have a suggestion for localizing an <asp:DropDownList... control using the Umbraco Dictionary?

I see this snippet is the pattern for file-based localization, but was looking for a more Umbraco'ish approach:

protected override void OnPreRender(EventArgs e)
{
    ResourceManager rm = ResourceManager.CreateFileBasedResourceManager("Country",
    Server.MapPath("~/Resources") + Path.DirectorySeparatorChar, null);
    
    ResourceSet rs = rm.GetResourceSet(CultureInfo.CurrentCulture, false, true);
    
    CountryList.DataSource = rs;
    CountryList.DataTextField = "Value";
    CountryList.DataValueField = "Key";
    CountryList.DataBind();
}

Thank you
