C# Switch with When Clause Example – Smarter Condition Handling!
Hey There! Ready to Level Up Your Switch Case? 🎯
So, you’ve mastered the basic switch case in C#, right? But here’s the thing—what if you need extra conditions inside a switch case? 🤔
That’s where when Clause comes in! It adds conditions inside case statements to make your switch even more powerful! 🚀
Let’s dive into this awesome feature with real-world examples! 🎉
📚 What You Are Going to Learn in This Lesson
✅ What is switch with when Clause C# example?
✅ Why should you use when inside a switch?
✅ Real-world example with full code + output!
✅ How it makes switch cleaner and smarter!
🎯 What is Switch with When Clause?
A when Clause in a switch statement lets you add conditions to specific case labels. It helps avoid unnecessary nested if-else statements and makes your code easier to read! 😍
📌 Syntax of Switch with When Clause in C#
switch (expression)
{
case pattern1 when (condition1):
// Code block 1
break;
case pattern2 when (condition2):
// Code block 2
break;
default:
// Default case
break;
}
✅ when (condition) → Adds extra logic to a case.
✅ Executes only if both pattern & condition match.
💡 Real-World Example: Movie Ticket Pricing 🎟️
Imagine you’re building a movie ticket system. The price depends on:
🎯 Age of the customer (kids & seniors get discounts).
🎯 Time of the day (morning shows are cheaper).
Here’s how switch with when Clause makes this super easy! 🚀
using System;
class Program
{
static void Main()
{
int age = 65; // Try changing to 10, 30, or 80
string time = "morning"; // Try changing to "evening"
int ticketPrice = (age, time) switch
{
(<= 12, _) => 5, // Kids get $5 tickets anytime
(>= 60, "morning") => 6, // Seniors get $6 tickets in the morning
(>= 60, "evening") => 8, // Seniors pay $8 in the evening
(_, "morning") => 10, // Morning show for adults is $10
(_, "evening") => 15, // Evening show for adults is $15
_ => 12 // Default price
};
Console.WriteLine($"Ticket Price: ${ticketPrice}");
}
}
📌 Code Breakdown – What’s Happening?
- Checks age & time inside a switch expression.
- Uses
_wildcard when a condition isn’t needed. - Short and clean! No need for long if-else statements.
🎬 Output Examples
If age = 65 and time = "morning"
Ticket Price: $6
(Senior discount for morning shows! 🎉)
If age = 10 and time = "evening"
Ticket Price: $5
(Kids always get the cheapest tickets! 🧒🎟️)
If age = 30 and time = "evening"
Ticket Price: $15
(Full price for an evening movie! 🌆🎥)
🎯 Why Use Switch with When Clause?
✅ Removes unnecessary if-else chains 🏗️
✅ Handles multiple conditions easily 🛠️
✅ More readable & cleaner code 🧼
✅ Perfect for complex decision-making 🤖
