I don't know if this is a bug, or I am using the Bitconverter class incorrectly. I basically wanted to get the mac address of my unit and then convert it into a string like so:

byte[] macBytes = Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()[0].PhysicalAddress;

string macAddress = BitConverter.ToString(macBytes); //application crashes here

My Netduino Plus 2 becomes unresponsive and I cannot upload new programs to it even after a power reset. The only way to regain control of it is to reflash the firmware. I am using firmware v4.3.1 . Can anybody else try this and see if they get the same results?

 

Thanks

Verified.  Same issue using bitconverter.tostring(). Have to reflash.
 
my quick workaround is;
 

const string hexChars = "0123456789ABCDEF";
static string BugWorkAroundToString(byte[] buf)
{
   string s = "0x";
            
   foreach (byte b in buf)
   {
       s += hexChars[b >> 4];
       s += hexChars[b & 0x0F];
   }
   return s;
}

You can also use,

byte B = 0xac;
String S = B.ToString("X2");
Debug.Print(S); //--> AC

Thanks guys! I just wanted to make sure it wasn't a hardware issue or defect with my Netduino.
