Question

I have this method and get the above error on the line words.Add(rows); can anyone help? Thanks – Ben

private static IEnumerable<string> LoadWords(String filePath)
    {

        List<String> words = new List<String>();

        try
        {
            foreach (String line in File.ReadAllLines(filePath))
            {
                string[] rows = line.Split(',');

                words.Add(rows);
            }

        }
        catch (Exception e)
        {
            System.Windows.MessageBox.Show(e.Message);
        }

            return words;
    }

Instead of

words.Add(rows);

use this :

words.AddRange(rows);

rows is a string array containing multiple strings, so you have to add them with AddRange().
