C# Function Examples

In this chapter you will learn how to create and use function in program.

Example

Qu. Write a program to explain method in C#. Create a static function add() that accept two number from user and returns sum of the number.
Answer
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5.  
  6. namespace Example1
  7. {
  8.     class calculation
  9.     {
  10.         static int num1, num2, result;
  11.         public static void add()
  12.         {
  13.             Console.Write("Enter number 1st.\t");
  14.             num1 = Convert.ToInt32(Console.ReadLine());
  15.  
  16.             Console.Write("Enter number 2nd.\t");
  17.             num2 = Convert.ToInt32(Console.ReadLine());
  18.  
  19.             result = num1 + num2;
  20.  
  21.             Console.Write("\nAdd = {0}", result);
  22.             Console.ReadLine();
  23.         }
  24.     }
  25.     class Program
  26.     {
  27.         static void Main(string[] args)
  28.         {
  29.             calculation.add();
  30.         }
  31.     }
  32. }

Output

Enter number 1st.      6

Enter number 2nd.     8

Add = 14
