Ive written a simple line which converts a byte array to a hex string:-<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; urlSafe = BitConverter.ToString(byt2<wbr />Convert).R<wbr />eplace(&quot;-&quot;<wbr />, &quot;&quot;)<br />

However I have no idea how to convert back to a byte array? Does anyone?<br />
<br />
I cant seem to find any example code as simple as converting it from byte to string.<br />
<br />
Any ideas?<br />
<br />
Thank you
