Question

I’m starting with the two values below:

finalString = "38,05,e1,5f,aa,5f,aa,d0";
string[] holder = finalString.Split(',');

I’m looping thru holder like so:

foreach (string item in holder)
{
  //concatenate 0x and add the value to a byte array
}

On each iteration I would like to concatenate a 0x to make it a hex value and add it to a byte array.

This is what I want the byte array to be like when I finish the loop:

byte[] c = new byte[]{0x38,0x05,0xe1,0x5f,0xaa,0x5f,0xaa,0xd0};

So far all my attempts have not been successful. Can someone point me in the right direction?

Answer 1

You don’t have to concatenate the prefix “0x”. This prefix is used by the C# compiler when parsing literals, but byte.Parse doesn’t use it

byte[] myByteArray = new byte[holder.Length];
int i = 0;
foreach (string item in holder)
{
    myByteArray[i++] = byte.Parse(item, System.Globalization.NumberStyles.AllowHexSpecifier); 
}
