Byte Array Conversion

I'm trying to read data after making a winsock call.  the data I get back is a byte array.  the problem i'm having is the data is mixed data types.  I can't just convert it all to strings as it has integer, byte, string, and float datatypes.  I'm not sure how to go about parsing this byte array to get the data i need.  I beleve the data is chr(0) seperated but the problem is the integer can have a 0 value.  I'm not sure how to tell the two apart in a byte array.  any help would be great

the format is . . .

      (int32)            -1
      (byte)            ASCII 'D' (players response, S2A_PLAYER)
      (byte)            active client count

      for each active client
            (byte)            client number / index
            (string)            player name
            (int32)            client's frag total
            (float32)            client's total time in-game
