Program :

using System;

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;
    }
  }
}

using System;

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.
