I'm not sure exactly what you are referring to here but I am assuming that
you are receiving data from an api call that is a byte array, into a
string, and you want to create a hex string that represents the byte
data. If so, then this should do it depending on which Encoding will work
for you:
// test string
string theString = System.Text.ASCIIEncoding.Unicode.GetString(
new byte[] {15, 16, 1, 29, 210, 44, 5, 255}
);
// issue here is whether the Unicode or ASCIIEncoding is correct or neither
byte[] data = System.Text.UnicodeEncoding.Unicode.GetBytes(theString);
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (byte b in data)
{
if (b < 16)
b.ToString("0");
sb.Append(b.ToString("X"));
}
An issue I see with your logic, if I am understanding you correctly, is
that a byte array containing 0 and 10 does not hex encode to "0A", but
rather to "000A". Otherwise you would hex decode "0A" to a single element
byte array of conataining 10.
