Question

I can say I don’t know what I’m asking for help,because I don’t know the format,but I’ve got a picture.

I have a byte[] array ,how do I convert it to that format below(in right)?

Its not plain ascii.

Answer 1

Use b.ToString("x2") to format a byte value into a two character hexadecimal string.

For the ASCII display, check if the value corresponds to a regular printable character and convert it if it is:

if (b >= 32 && b <= 127) {
   c = (char)b;
} else {
   c = '.';
}

Or shorter:

c = b >= 32 && b <= 127 ? (char)b : '.';

To do it on an array:

StringBuilder builder = new StringBuilder();
foreach (b in theArray) {
   builder.Append(b >= 32 && b <= 127 ? (char)b : '.');
}
string result = builder.ToString();
