i have a hex file in that have 40000 records.
i want to read data segment from 2nd line.
i am able to read data per line and i have stored in char array. but that is containing 32 size of array. and in file that data size is 16 byte.
i want to convert char array in hexadecimal.and want to match with each line contain in intel hex file.

C#

openFileDialog1.Title = "Select a Hex file";
openFileDialog1.DefaultExt = "*.hex";
openFileDialog1.Filter = "HEX Files|*.hex";
if (openFileDialog1.ShowDialog() != System.Windows.Forms.DialogResult.Cancel &&
openFileDialog1.FileName.Length > 0)
{
richTextBox3.Text = System.IO.Path.GetFullPath(openFileDialog1.FileName);

}
string PathofFile = System.IO.Path.GetFullPath(openFileDialog1.FileName);
StreamReader Sr = new StreamReader(PathofFile);
string FileReader = Sr.ReadToEnd();
int CountLines = File.ReadLines(PathofFile).Count();

for (int i = 1; i < CountLines - 2; i++)
{
// string LineReader = File.ReadLines(PathofFile).Take(i).ToString();
string[] lines = File.ReadAllLines(PathofFile);
string line = lines[i];
//int ByteCount = line.Count();
//char *ptr = null;
char[] b = new char[line.Length -11];
using (StringReader ss = new StringReader(line))
{
// ss.Read(b,9,41);
ss.Read(b,0,9);
ss.Read(b,0,32);
byte[] ByteArr = Convert.FromBase64CharArray(b, 0, b.Length);

string hex = BitConverter.ToString(ByteArr).Replace("-", "");



the value which is coming in string hex is in different format i want it to be in format that contain our intel hex file

@ ryan now u can see the changed

You seem to be reading and re-reading the file content more times than necessary. Could you also show the exact format of one of the lines in your text file, as it is not clear what it looks like?

what's the format in the file and what format do you want? so can you please show it, will try to help, but I don't want to guess...

Hey, kumar9avinash.
You said you have got hex file. I want to know something. Your hex file is written in text file or binary file?

@ richard see i have got the above solution but now i am reading this in char array of size 32 (B80C001061020000690200006B020000) but now i want to read as 1 byte of (b8),2nd byte (oc) so that it become 16 byte array , now its 32 byte array .

my last code is
for (int i = 1; i < CountLines - 2; i++)
{
string[] lines = File.ReadAllLines(PathofFile);
string line = lines[i];
char[] B = new char[line.Length - 11];
int charcount = B.Count();
using (StringReader Ss = new StringReader(line))
{
Ss.Read(B, 0, 9);
Ss.Read(B, 0, B.Length);
string Hexdata = new string(B);

That code makes no sense to me, and is just the same as in your original question. Why not just take each two characters in turn and use the Int.Parse() method to convert to its byte value?

Well, I've made simple code for reading binary hex file.

C#

 opfn.Title = "Select a Hex file";
opfn.DefaultExt = "*.hex";
opfn.Filter = "HEX Files|*.hex";

if (opfn.ShowDialog() == DialogResult.Cancel)
    return;

// get selected filename and open it with binarystream
string strPath = System.IO.Path.GetFullPath(opfn.FileName);
BinaryReader binReader = new BinaryReader(File.Open(strPath, FileMode.Open));

// get file length and alloc butter
long lfileLength = binReader.BaseStream.Length;
Byte[] btFile = new Byte[lfileLength];

// read every byte of file's content
for (long lIdx = 0; lIdx < lfileLength; lIdx++)
{
    btFile[lIdx] = binReader.ReadByte();
}

I hope this will great help you.
