C# Question

Well,

Here is what I need to do:

I need to split the text from a .txt file into a list of the words in the file (which I have done) I then need to count each word and list them so that there are no repeating words in the list ( each word appears only one with a number next to it representing how many times it occurs). I am assuming I can use a hashtable for this but don't know where to begin.

The next thing I need to do is, perform an http request and find the top 5 google searched for the 3 words that appear the most and display the results.

Here is what i have so far:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Text.RegularExpressions;
using System.Collections;

namespace ConsoleApplication2
{
    class SplitTextFile
    {
        static void Main(string[] args)
        {
            FileStream file = new FileStream("input.txt", FileMode.OpenOrCreate, FileAccess.Read);
            StreamReader sr = new StreamReader(file);
            string s = sr.ReadToEnd();
            sr.Close();
            file.Close();
            char[] delim = { ' ', '\t', '\r', '\n' };
            string[] words = s.Split(delim);
            foreach (string word in words)
            {
                Console.WriteLine(word);
            }
            Console.ReadLine();
        }
    }

}

Here is what I have so far, but it doesn't work. Any ideas why?

            char[] delim = { ' ', '\t', '\r', '\n' };
            wordFreq = new Hashtable();
            string[] words = s.Split(delim);
            foreach (string word in words)
            {
                if (words[i] != "")
                {
                    bool realWord = true;
                    for (int j = 0; j < words[i].Length; j++)
                    {
                        if (char.IsLetter(words[i][j]) == false)
                        {
                            realWord = false;
                        }
                    }

                    if (realWord == true)
                    {
                        if (wordFreq.Contains(words[i].ToLower()))
                        {
                            wordFreq(words[i].ToLower()) += 1;
                        }
                        else
                        {
                            wordFreq.Add(words[i].ToLower(), 1);
                        }
                    }
                }
            }
            this.wordCount = new SortedList();

            foreach (DictionaryEntry de in wordFreq)
            {
                if (wordCount.ContainsKey(de.Value) == false)
                {
                    wordCount.Add(de.Value, de.Key);
                }
            }
        }

     }
}
