How I know that a property is related to a xml file

public static void Retrieve(string resPathName)

{

    try

    {

        //Create a new ResXResource reader and set the resx path to resxPathName

        ResourceReader resReader = new ResourceReader(resPathName);

        //Enumerate the elements within the resx file and dispaly them

        foreach (DictionaryEntry d in resReader)

        {

            MessageBox.Show(d.Key.ToString() + “ : “ + d.Value.ToString());

        }

        //Close the resxReader

        resReader.Close();

        MessageBox.Show(“Done”);

    }

    //If the resx file represents some incoherences 

    catch (ArgumentException caught)

    { MessageBox.Show(“Source: “ + caught.Source + “Message: “ + caught.Message); }

}
