How will you make a combination of the Enum values in C# ? Explain with an example.

Answer:

In C#, we have to decorate the Enum with Flag attribute and use a bitwise operator to make a combination of the values.

Let us look at the below example

class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine(Fruits.AllFruits.HasFlag(Fruits.Guava));

            Console.ReadKey();



        }



        [Flags]

        enum Fruits

        {

            Apple = 1,

            Mango = 2,

            Banana = 3,

            Guava = 4,

            AllFruits = Apple | Mango | Banana | Guava,

            AppleANDGuava = Apple & Guava          

        }



    }



/* Result */

True

We are checking if the Guava is present in the "AllFruits" enum.
