Enum with switch pattern in C Sharp (C#) - Mini Project: Build & Apply

Enum with switch pattern

📖 Scenario: You are creating a simple program to describe different weather conditions using an enum. You want to print a message based on the weather type.

🎯 Goal: Build a program that uses an enum for weather types and a switch expression to print a message for each weather.

📋 What You'll Learn

Create an enum called Weather with values Sunny, Rainy, Cloudy, and Snowy

Create a variable today of type Weather and set it to Weather.Sunny

Use a switch expression on today to get a message string

Print the message string

💡 Why This Matters

🌍 Real World

Enums and switch expressions are common in programs that need to handle fixed categories like weather, traffic lights, or user roles.

💼 Career

Understanding enums and switch expressions helps you write clear and maintainable code in many software development jobs.

1

Create the Weather enum

Create an enum called Weather with these exact values: Sunny, Rainy, Cloudy, and Snowy.

C Sharp (C#)

# Your code here

Need a hint?

An enum groups related named values. Use enum Weather { Sunny, Rainy, Cloudy, Snowy }.

2

Create a variable for today's weather

Create a variable called today of type Weather and set it to Weather.Sunny.

C Sharp (C#)

enum Weather
{
    Sunny,
    Rainy,
    Cloudy,
    Snowy
}

// Your code here

Need a hint?

Declare Weather today = Weather.Sunny; to set the current weather.

3

Use a switch expression to get a message

Create a string variable called message and assign it the result of a switch expression on today. Use these exact cases:
Weather.Sunny => "It's a bright sunny day!"
Weather.Rainy => "Don't forget your umbrella."
Weather.Cloudy => "It might rain later."
Weather.Snowy => "Time to build a snowman!"

C Sharp (C#)

enum Weather
{
    Sunny,
    Rainy,
    Cloudy,
    Snowy
}

Weather today = Weather.Sunny;

// Your code here

Need a hint?

Use a switch expression with today switch { ... } to assign message.

4

Print the message

Write a Console.WriteLine statement to print the message variable.

C Sharp (C#)

enum Weather
{
    Sunny,
    Rainy,
    Cloudy,
    Snowy
}

Weather today = Weather.Sunny;

string message = today switch
{
    Weather.Sunny => "It's a bright sunny day!",
    Weather.Rainy => "Don't forget your umbrella.",
    Weather.Cloudy => "It might rain later.",
    Weather.Snowy => "Time to build a snowman!",
    _ => "Unknown weather"
};

// Your code here

Need a hint?

Use Console.WriteLine(message); to show the message on screen.
