title: How do I convert hex string into signed integer?
body: <p>I'm getting a hex string that needs to be converted to a signed 8-bit integer.  Currently I'm converting using Int16/Int32, which will obviously not give me a negative value for an 8-bit integer.  If I get the value 255 in Hex, how do I convert that to -1 in decimal?  I assume I want to use an sbyte, but I'm not sure how to get that value in there properly.</p>
