Convert comma separated binary string to byte[] for Registry insertion

This is really getting the better of me. I need to convert this:

string data = "4,0,0,0,1,0,0,0,16,0,0,0,100,58,82,80,162,77,200,183,178,32"

into a byte array so that I can use it here:

polKey.SetValue("Blob", data, RegistryValueKind.Binary);

I've tried data.Split(',') to split it into an array and use that, but I can't get my head around it.

You can use Linq

string data = "4,0,0,0,1,0,0,0,16,0,0,0,100,58,82,80,162,77,200,183,178,32";
var buf = data.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries)
              .Select(x => byte.Parse(x))
              .ToArray();

A regex solution is also possible

var buf = Regex.Matches(data,@"\d+").Cast<Match>()
               .Select(x => byte.Parse(x.Value))
               .ToArray();

I'm assuming your byte array needs the parsed values (e.g. 4, 0, 1, 100, etc.) and not the ASCII values of each string.

First convert to an array of strings:

string[] strings = data.Split(',');

then convert each string to a byte:

byte[] bytes = strings.Select(s => byte.Parse(s)).ToArray();
