The following example attempts to convert each element in a byte array to a signed byte.
byte[] numbers = { Byte.MinValue, 10, 100, Byte.MaxValue }; sbyte result; foreach (byte number in numbers) { try { result = Convert.ToSByte(number); Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.", number.GetType().Name, number, result.GetType().Name, result); } catch (OverflowException) { Console.WriteLine("The {0} value {1} is outside the range of the SByte type.", number.GetType().Name, number); } } // The example displays the following output: // Converted the Byte value 0 to the SByte value 0. // Converted the Byte value 10 to the SByte value 10. // Converted the Byte value 100 to the SByte value 100. // The Byte value 255 is outside the range of the SByte type.
