namespace AddTwoNumsUsingFunc
{
    class Program
    {
        static void Main(string[] args)
        {
            int x, y, result = 0;
            Console.WriteLine("*** www.ProgrammingPosts.blogspot.com *** ");
            Console.WriteLine(">>>C# PROGRAM TO ADD TWO NUMBERS USING METHOD <<< ");
            Console.Write("\n Enter the first number to be added: ");
            x = Convert.ToInt32(Console.ReadLine());         // taking x value from keyboard
            Console.Write("\n Enter the second number to be added: ");
            y = Convert.ToInt32(Console.ReadLine());         // taking y value from keyboard
            result = Sum(x, y);     //calling function

            Console.WriteLine("\n The sum of two numbers is: {0} ", result);    /*printing the sum.*/
            Console.ReadLine();
        }

        static public int Sum(int a, int b)
        {
            int result = a + b;
            return result;
        }   


    }
}

Sample Output :
Explanation : In the above program the method static public int Add(int a,int b) , we are declaring method Sum method as Static because Main method is static and we are calling Sum method in Main method without creating object. 
c# is a Object Oriented Programming Language. And in OOP language, a method can be called using object of a class. And if we want to call method without creating object, we have to declare it as static to Call it with its class name.
