How do I use C# to convert int to bytes that only use the low 4 bits?
<p>I have a conversion problem in C#. Basically, I'm trying to convert an integer to bytes so that we only use the low 4 bits. Example <code>255 = 0F 0F</code> or:</p>

<pre><code>0xpqrs = 0p 0q 0r 0s

5*16*16*16 + 1*16*16 + 15*16 + 1  = 05 01 0f 01
</code></pre>

<p>How do I implement this in C#?</p>
