Question

This might sound odd, but my issue is that I have a text string of hex values from a text file, like so:

"0x0f, 0x40, 0xff, ...."

I have stored them in an array split by the delimiters, but what I now need to do is have a byte array of what thay are in hex:

stringArray[0] = "0x0f";

byteArray[0] = 0x0f;

How do I do this (the user can load the text file, so I don’t know what the values are), is there some sort of arithmetic I can use?

You just have to parse each string. Because each one is already only one value, you can do this:

byte b;
if (byte.TryParse(s, NumberStyles.HexNumber, 
    CultureInfo.InvariantCulture.NumberFormat, out b)) 
{
    // b contains the value.
}

where s is the string you want to parse, and b is the resulting value.
