public void ConvertByteSingle(byte byteVal) { float floatVal; // Byte to float conversion will not overflow. floatVal = System.Convert.ToSingle(byteVal); System.Console.WriteLine("The byte as a float is {0}.", floatVal); // Float to byte conversion can overflow. try { byteVal = System.Convert.ToByte(floatVal); System.Console.WriteLine("The float as a byte is {0}.", byteVal); } catch (System.OverflowException) { System.Console.WriteLine( "The float value is too large for a byte."); } }
