when i run the program MyKwic sampleText(text file saved in the project) the compiler cannot trace the sampleText.
using System;
using System.Collections;
using System.Linq;
using System.Text;
using System.IO;
public class Mykwic
{
static void Main(string[] args)
{
if (args.Length == 0)
{
Console.WriteLine("Error: Missing file name");
return;
}
StreamReader reader = null;
Hashtable table = new Hashtable();
try
{
reader = new StreamReader(args[0]);
for (string line = reader.ReadLine(); line != null; line = reader.ReadLine())
{
string[] words = GetWords(line);
foreach (string word in words)
{
string iword = word.ToLower();
if (table.ContainsKey(iword))
table[iword] = (int)table[iword] + 1;
else
table[iword] = 1;
}
}
SortedList list = new SortedList(table);
Console.WriteLine("{0} unique words found in {1}", table.Count, args[0]);
foreach (DictionaryEntry entry in list)
Console.WriteLine("{0} ({1})", entry.Key, entry.Value);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
finally
{
if (reader != null)
reader.Close();
}
}
static string[] GetWords(string line)
{
ArrayList al = new ArrayList();
int i = 0;
string word;
char[] characters = line.ToCharArray();
while ((word = GetNextWord(line, characters, ref i)) != null)
al.Add(word);
string[] words = new string[al.Count];
al.CopyTo(words);
return words;
}
static string GetNextWord(string line, char[] characters, ref int i)
{
while (i < characters.Length && !Char.IsLetterOrDigit(characters[i]))
i++;
if (i == characters.Length)
return null;

}
}
