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

        try

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

                words.Add(rows);
            }

        }

.Add will take another string, not an array of strings.

Try .AddRange instead.

You are trying to add a string array to a list that takes a string.

Try words.AddRange(rows);

Have a try of this:

words.AddRange(rows);

You are using the wrong method. You want the AddRange method.

words.AddRange(rows);

Change it to this

words.AddRange(rows);

You issue is that you are adding an array of items, not a single element.

You use AddRange() when adding a collection that implements System.Collections.Generic.IEnumerable<T>

See documentation here http://msdn.microsoft.com/en-us/library/z883w3dc.aspx

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().
