Conversion from Linq to String

Am newbie here and tried the search, but not quite understood it, so I am thinking to ask to the forum for help.

I want to get the result into the text box from the following code but got an error. Confused on how to overcome it, appreciate for any help. I believe it was an error on the conversion from linqIgroup to string to be put in textboxt.Text

It's about to display the most word(s) that has been occurred in a text file.

string sentence;
        string[] result = {""};
        sentence = txtParagraph.Text;
        char[] delimiters = new char[] { ' ', '.', '?', '!' };

        string[] splitStr = sentence.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
        var dic = splitStr.ToLookup(w => w.ToLowerInvariant());
        var orderedDic = dic.OrderByDescending(g => g.Count(m=>m.First()).ToString()));

        txtFreqWord.Text = orderedDic.ToString();

Try the following to do what you are after. I am using regular expressions aswell.

            var resultsList = System.Text.RegularExpressions.Regex.Split("normal text here normal normal".ToLower(), @"\W+") 
        .Where(s => s.Length > 3)
        .GroupBy(s => s)
        .OrderByDescending(g => g.Count());

        string mostFrequent = resultsList.FirstOrDefault().Key;

To get all of them with their count, do the following : 

            foreach (var x in resultsList) {
                 txtFreqWord.Text = txtFreqWord.Text + x.Key + " " + x.Count() +", ";
            }
