C# Return Statement

In this chapter you will learn:

• What is the return statement in C#?
• What is the functionality of return statement?
• How to use return statement in programming?

A return statement is used for returning value to the caller from the called function. An easy example is mentioned below in a program that demonstrates the return statement very clearly.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace return_statements
{
    class Program
    {
        public int add(int num1, int num2)
        {
            // returns the add of num1 and num2
            return num1 + num2;
        }
        static void Main(string[] args)
        {
            Program p = new Program();
            int result;
            // calling the function add that will return 9 to the result vaiable.
            result = p.add(3, 6);
            Console.WriteLine(result);

            Console.ReadLine();
        }
    }
}

In this example the variable result calls the function add() with two parameters and the function add() returns addition of both number to the result variable using return keyword.

Output

9
