C Sharp (C#) Byte and sbyte Data Type

Byte datatype has a range from 0 to 255 and can be assigned as below :
byte b = 255

In the preceding declaration, the integer literal 255 is implicitly converted from int to byte. If the integer literal exceeds the range of byte, a compilation error will occur. There is a predefined implicit conversion from byte to short, ushort, int, unit, long, ulong, float, double, decimal.

Similarly an sbyte is a signed byte which has a limit from -128 to +127. The following example shows the usage of both signed and unsigned byte when values are within and outside the limits.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication

{

    class Program

    {

        static void Main(string[] args)

        {

            byte a = 100;

            byte b = 100;

            byte c = (byte)(a + b);

            Console.WriteLine("The addition of two unsigned byte numbers {0} and {1} is : {2}", a, b, c);

            Console.ReadLine();

            sbyte d = 100;

            sbyte e = 100;

            sbyte f = (sbyte)(d + e);

            Console.WriteLine("The addition of two signed byte numbers {0} and {1} is : {2}", d, e, f);

            Console.ReadLine();

        }

    }

}
