storing hex from text file into byte array

Question

how would i go about taking characters from a text and storing them in a byte array? by hex characters i mean the text file reads "00 9A 6F AE" etc. etc.

does system.io.streamreader only store data as strings?

and id like to store it in a byte[], instead of manually typing
{ 0x00, 0x9a, 0x6f, 0xae } into the code itself.

thanks,
mythos

Try this (.NET 2.0 or later): using System; using System.IO; using System.Collections.Generic; class Program { static void Main() { string[] lines = File.ReadAllLines(myfile.txt); // say List list = new List (); foreach(string line in lines) { string[] hexes = line.Split(' '); foreach (string hex in hexes) { list.Add(Convert.ToByte(hex 16)); } } byte[] bytes = list.ToArray(); // check it worked Console.Write({ ); for(int i = 0; i { Console.Write(0x + bytes[i].ToString(x2)); if (i } Console.WriteLine( }); Console.ReadKey(); } }
