Returning Array from Methods in C# with Easy Examples
👋 Introduction
Hey friend! Have you ever wanted to perform a task in a method and get back a bunch of values at once? 🤔 Imagine you ask your friend to grab snacks 🍫🍿🍩 and they come back with a whole bag full of goodies—that bag is like an array being returned from a method!
In C#, methods can return arrays, allowing you to send back multiple values neatly packed together. This is super useful when you need more than just one piece of information. Sounds exciting, right? 😃 Let’s learn how!
📚 What You Are Going to Learn in This Lesson:
✔️ What is returning an array from a method?
✔️ How to write methods that return arrays in C#.
✔️ Simple syntax with clear explanations.
✔️ Real-world examples and fun programs.
✔️ Complete code with outputs and detailed explanations.
📝 Basic Syntax:
Here’s how you define and use a method that returns an array:
returnType[] MethodName(parameters)
{
// Create an array
return arrayName; // Return the array
}
returnType[]: Type of array returned (e.g.,int[],string[]).MethodName: Name of the method.return: Sends the array back to where the method was called.
💻 Example 1: Return an Array of Integers
Let’s start with a simple program that returns numbers.
using System;
class Program
{
// Method returning an integer array
static int[] GetNumbers()
{
int[] numbers = { 10, 20, 30, 40, 50 };
return numbers; // Returning the array
}
static void Main()
{
int[] result = GetNumbers(); // Call method and get array
Console.WriteLine("Returned Array: " + string.Join(", ", result));
}
}
🎯 Output:
Returned Array: 10, 20, 30, 40, 50
🧠 Explanation:
GetNumbers()creates an array of integers and returns it.- In
Main(), the returned array is stored inresult. string.Join(", ", result)displays the array nicely.
👉 Easy peasy, right? Like grabbing a handful of candies! 🍬
🍎 Example 2: Return an Array of Strings (Favorite Fruits)
Let’s return some delicious fruits! 🍌🍓🍍
using System;
class Program
{
// Method returning a string array
static string[] GetFruits()
{
return new string[] { "Apple", "Banana", "Cherry", "Date" };
}
static void Main()
{
string[] fruits = GetFruits(); // Call method to get fruits
Console.WriteLine("Fruits: " + string.Join(", ", fruits));
}
}
🎯 Output:
Fruits: Apple, Banana, Cherry, Date
👉 Like ordering a fruit basket and getting back all the goodies! 🥭🍒
🧮 Example 3: Return an Array from Calculations (Squares of Numbers)
Let’s make a method that returns the squares of numbers. Ready? 😎
using System;
class Program
{
// Method that returns an array of squares
static int[] GetSquares(int count)
{
int[] squares = new int[count];
for (int i = 0; i < count; i++)
{
squares[i] = (i + 1) * (i + 1); // Calculate square
}
return squares; // Return the array
}
static void Main()
{
int[] squares = GetSquares(5); // Get first 5 squares
Console.WriteLine("Squares: " + string.Join(", ", squares));
}
}
🎯 Output:
Squares: 1, 4, 9, 16, 25
🧠 Explanation:
GetSquarescalculates and returns an array of square numbers.- The loop fills the array with squares of numbers from 1 to
count. - The result is displayed using
string.Join.
👉 Math made fun! Your calculator might get jealous. 🧷😄
🌍 Example 4: Real-World Scenario - Weekly Temperatures 🌡️
Imagine you’re tracking daily temperatures for a week. Here’s how you return that data!
using System;
class Program
{
// Method returning an array of temperatures
static double[] GetWeeklyTemperatures()
{
return new double[] { 72.5, 74.0, 73.2, 71.8, 75.6, 76.1, 74.4 };
}
static void Main()
{
double[] temps = GetWeeklyTemperatures(); // Get temperatures
Console.WriteLine("Weekly Temperatures: " + string.Join("°F, ", temps) + "°F");
}
}
🎯 Output:
Weekly Temperatures: 72.5°F, 74°F, 73.2°F, 71.8°F, 75.6°F, 76.1°F, 74.4°F
👉 Now you can plan whether it’s a beach day or a hot cocoa day! 🏖️☕
