Tutorial :How would I read an ascii string of hex values in to a byte array?



Question:

How would I copy/convert a string containing an ascii representation of hex values in to a byte array containing the actual hex values? For example, I have a variable containing the hex values delimited by spaces (I can change the delimiter):

myString = "24 01 66 09 13 2F 1E 00 00 4E"

I want to put those values into a byte array:

Dim myByteArr(9) as Byte


Solution:1

Public Shared Function HexToBytes(ByVal s As String) As Byte()      Dim bytes As String() = s.Split(" "c)      Dim retval(bytes.Length - 1) As Byte      For ix As Integer = 0 To bytes.Length - 1          retval(ix) = Byte.Parse(bytes(ix), System.Globalization.NumberStyles.HexNumber)      Next      Return retval  End Function
