Hi Jegan Priya,

        There is three ways available to achieve your requirement. Please have the following link

Access the private member using reflection

As we know, reflection is a way to access the members of a class. So we can use the "System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance" flags using the GetField method, as per the following code.

namespace Access_Private_Member

{

    class Program

    {

        static void Main(string[] args)

        {

            ExampleOne one = new ExampleOne();

        }

    }

    public class Tamil

    {

        private string message = "தமிழ் வாழ்க!";

    }

    public class ExampleOne : Tamil

    {

        public ExampleOne()

        {

            System.Reflection.FieldInfo receivedObject = typeof(Tamil).GetFields(System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance)[0];

            var obj = receivedObject.GetValue(this);

            MessageBox.Show("Access the private member using Reflection \n "+obj.ToString());

        }

    }

Access the private member using base by sub-class

This is another way that uses the class as a sub-class and accesses the private member using the base. The following code demonstrates the logic.

namespace Access_Private_Member

{

    class Program

    {

        static void Main(string[] args)

        {

            TamilValga.ExampleTwo two = new TamilValga.ExampleTwo();

         }

    }

    public class TamilValga

    {

        private string message = "தமிழ் வாழ்க!";

        public class ExampleTwo : TamilValga

        {

            public ExampleTwo()

            {

                MessageBox.Show("Access the private member using base by sub-class \n " + base.message);

            }

        }

    }

}

Access the private member by methods

This is a very simple way to access the private member of a class without inheriting the class by declaring a public method of the same class as per the following code.

namespace Access_Private_Member

{

    class Program

    {

        static void Main(string[] args)

        {

            Tamil three = new Tamil();

            MessageBox.Show("Acess the private member by methods \n" + three.AccessPriveMemberMessage("தமிழ் வாழ்க! தமிழ் வளர்க!!"));

         }

    }

    public class Tamil

    {

        private string message = "தமிழ் வாழ்க!";

        public  string AccessPriveMemberMessage(string value)

        {

            message = value;

            return message;

        }

    }

}
