Write bytes to file

Question

I have a hexadecimal string (e.g 0CFE9E69271557822FE715A8B3E564BE) and I want to write it to a file as bytes. For example,

Offset      0  1  2           


        

Answer 1

If I understand you correctly, this should do the trick. You'll need add using System.IO at the top of your file if you don't already have it.

public bool ByteArrayToFile(string fileName, byte[] byteArray)
{
    try
    {
        using (var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write))
        {
            fs.Write(byteArray, 0, byteArray.Length);
            return true;
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception caught in process: {0}", ex);
        return false;
    }
}
