Hello,
What is the error of my overloading example?

C#

namespace MethodOverloading
{
    class Program
    {
        public class TestOverloading
        {
            public void Add(string a, string b)
            {
                Console.WriteLine("Adding Two String :" + a + " " + b);
            }
            public void Add(int a1, int a2)
            {
                Console.WriteLine("Adding Two Integer :" + a1 + a2);
            }

        }
        static void Main(string[] args)
        {
            TestOverloading obj = new TestOverloading();
            obj.Add("Ankit", "Agarwal");
            obj.Add(10,5);
            Console.ReadLine();
        }
    }
}

Output is coming:-
Adding Two String :Ankit Agarwal
Adding Two Integer :105

I want to add two integer value.
why is not coming correct output?

One step of abstraction above just fixing your code: when the Console.WriteLine arguments are evaluated the normal precedence of mathematical operators is ignored.

Solution 2

Try this

C#

int c = a1 + a2;
Console.WriteLine("Adding Two Integer :" + c);

Solution 1

Change the line to;

Console.WriteLine("Adding Two Integer :" + (a1 + a2));

Otherwise the first addition that takes place is between "Adding Two Integer :" and a1, the result of which is another string. Then when you add a2 to that you're concatenating again.

Hope this helps,
Fredrik
