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;
