Object - ToNullableByte

An object extension method that converts the @this to a nullable byte.

Try it

public static void Main()
{
    object[] values = { null, true, -12, 163, 935, 'x', "104", "103.0", "-1",
            "1.00e2", "One", 1.00e2};

    foreach (object value in values)
    {
        try
        {
            // C# Extension Method: Object - ToNullableByte
            byte? result = value.ToNullableByte();
            Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                              value != null ? value.GetType().Name : "null", value,
                               result != null ? result.GetType().Name : "null", result);
        }
        catch (OverflowException)
        {
            Console.WriteLine("The {0} value {1} is outside the range of the Byte type.",
                              value.GetType().Name, value);
        }
        catch (FormatException)
        {
            Console.WriteLine("The {0} value {1} is not in a recognizable format.",
                              value.GetType().Name, value);
        }
        catch (InvalidCastException)
        {
            Console.WriteLine("No conversion to a Byte exists for the {0} value {1}.",
                              value.GetType().Name, value);

        }
    }
}
