How do I convert from 8 bit byte to 7 bit byte (Base 256 to Base 128)
<p>How do I convert from 8 bit byte to 7 bit byte (Base 256 to Base 128)</p>

<p>I am looking to do something like this:</p>

<pre><code>public string BytesToString(byte[] in)
{

}

public byte[] StringToBytes(string in)
{

}
</code></pre>

<p>I know base64 is available but it expands a byte array too much.</p>
