What have you tried so far? What problems have you run into?

What's the purpose of your requirements? Skipping the first 9 characters, your would throw away imoprtant pieces of info.

Its hard to understand what it is you really want to do. Can you please rephrase your question.
Take a look at StreamReader class and Substring method in the string object.

You already posted this question at hex file parser in c #[^].
However, I answered a similar query yesterday so here is the code to convert it:

C#

int i = 0;
int index = 0;
byte[] hexBytes = new byte[sourceLine.Length /2];
do
{
    string hs = sourceLine.Substring(index, 2);
    hexBytes[i] = (byte)int.Parse(hs, System.Globalization.NumberStyles.AllowHexSpecifier);
    i++;
    index += 2;
} while (index < sourceLine.Length);
// hexBytes now contains the converted data

Read from the file and then copy the characters you are interested in into sourceLine and use the above code to convert it to its original binary values.
