Top-level statements in modern C# - Mini Project: Build & Apply

Top-level statements in modern C#

📖 Scenario: You are creating a simple console program to greet users by name. Modern C# allows writing code without explicitly defining a class or a Main method. This makes your program shorter and easier to read.

🎯 Goal: Build a small C# program using top-level statements that asks for the user's name and then greets them with a personalized message.

📋 What You'll Learn

Use top-level statements without defining a class or Main method

Read user input from the console

Print a greeting message including the user's name

💡 Why This Matters

🌍 Real World

Top-level statements simplify small C# programs, scripts, and quick tests by removing boilerplate code.

💼 Career

Understanding top-level statements helps you write cleaner, modern C# code used in many professional projects and interviews.

1

Create a variable to store the user's name

Write a line of code to declare a variable called name and assign it the value returned by Console.ReadLine().

C Sharp (C#)

# Declare a variable called name and assign it Console.ReadLine()
# Your code here

Need a hint?

Use string? name = Console.ReadLine(); to read input from the user.

2

Add a greeting message prefix

Create a variable called greeting and assign it the string "Hello".

C Sharp (C#)

string? name = Console.ReadLine();
# Create a variable called greeting and assign it "Hello"
# Your code here

Need a hint?

Use string greeting = "Hello"; to store the greeting word.

3

Combine greeting and name into a message

Create a variable called message and assign it the value of $"{greeting}, {name}!" using string interpolation.

C Sharp (C#)

string? name = Console.ReadLine();
string greeting = "Hello";
# Create a variable called message using string interpolation to combine greeting and name
# Your code here

Need a hint?

Use string message = $"{greeting}, {name}!"; to create the full greeting.

4

Print the greeting message

Write a line of code to print the message variable to the console using Console.WriteLine().

C Sharp (C#)

string? name = Console.ReadLine();
string greeting = "Hello";
string message = $"{greeting}, {name}!";
# Print the message to the console
# Your code here

Need a hint?

Use Console.WriteLine(message); to display the greeting.
