string:Hi how are you?

packet size:4

This will work for you, I assume you know how to read the lines from a file!!

string s = "Hi how are you?";
string[] words = new string[0];
int packetSize = 4;

while(s.Length > 0)
{
Array.Resize(ref words, words.Length + 1);
if (s.Length > packetSize)
words[words.Length - 1] = s.Substring(0, packetSize);
else
{
words[words.Length - 1] = s;
s = "";
}

if (s.Length > packetSize)
s = s.Substring(packetSize);

Easier to store it in a list, array is not resizable..If you want you can modify it to store in an array..
int packetSize = 4;
string test = File.ReadAllText(@"Path");
List lst = new List();
while (test.Length > packetSize)
{
     lst.Add(test.Substring(0, packetSize));
      test = test.Substring(packetSize);
}
if (test != string.Empty)
{
      lst.Add(test);
}

Hey,
Try this
1.
static void Main(string[] args)
{
var lines = File.ReadAllLines("filename.txt");
for (int i = 0; i < lines.Length; i++)
{
var fields = lines[i].Split(' ');
}
}
2.
string filePath = @"c:\words.txt"; // or whatever the path is
string text = System.IO.File.ReadAllText(filePath);
string[] words = text.Split(' ');
listBox1.DataSource = words;
