Welcome to our collection of C# practice exercises. Our exercises are designed to help you master the C# programming language and build your skills as a developer. Whether you’re a beginner just starting out or an experienced developer looking to brush up on your skills, our exercises will provide you with the knowledge and hands-on experience you need to succeed. Each exercise includes detailed explanations and sample code to help you understand the concepts and techniques involved. With our exercises, you’ll be able to build robust and scalable applications for Windows, web, and mobile platforms, utilizing features such as object-oriented programming, functional programming, and asynchronous programming. Start practicing today and take your C# skills to the next level!
C# Basic Exercises
1. Create a C# console application that displays “Hello World!” on the screen.
2. Write a program that takes a user’s name and age as input and displays a message on the console saying “Hello, [name]! You are [age] years old.”
3. Create a program that takes a number as input and displays the multiplication table of that number up to 10.
4. Write a program that takes a list of numbers as input and finds the largest and smallest number in the list.
5. Create a program that generates a random password for the user with a specified length and set of characters.
6. Write a program that takes a string input from the user and determines if it is a palindrome (a word or phrase that reads the same backward as forwards).
7. Create a program that calculates the factorial of a number input by the user.
8. Write a program that takes a sentence as input and converts it to pig Latin (a language game where words in English are altered by moving the first consonant or consonant cluster to the end of the word and adding “ay”).
9. Create a program that uses a loop to print out the numbers from 1 to 10.
10. Write a program that takes a list of names as input and sorts them alphabetically.
Note: These exercises are meant to be basic examples of C# console applications, and you can add more complexity and variation to them.
C# Advance Exercises
1. Create a C# Windows Forms application that uses object-oriented programming to create a simple calculator that can perform addition, subtraction, multiplication, and division.
2. Write a program that uses the Model-View-Controller (MVC) pattern to create a simple image viewer application that allows the user to open, view and edit image files.
3. Create a program that uses the ADO.NET library to connect to a database and perform CRUD (Create, Read, Update, Delete) operations on a table.
4. Write a program that uses the Asynchronous Programming pattern and the Task Parallel Library to create a multi-threaded application that performs a long-running task without freezing the UI.
5. Create a program that uses the LINQ (Language Integrated Query) to query and manipulate data in an XML document or a collection of objects.
6. Write a program that uses the Reflection API to inspect the types in an assembly and invoke methods dynamically.
7. Create a program that uses the Dependency Injection pattern to decouple the implementation of a class from its dependencies.
8. Write a program that uses the Event-Driven pattern to create a simple chat application that allows multiple users to send and receive messages.
9. Create a program that uses the SOLID principles to create a maintainable and extensible codebase.
10. Write a program that uses the ASP.NET Core framework to create a simple web application that allows users to register and log in, view and update their profile, and post and view messages on a forum. This application should include controllers, views, and models to handle the requests and responses and use the Razor engine to generate dynamic HTML pages.
Note: These exercises are more complex, and they are meant to be tackled by developers who have a good understanding of C#, object-oriented programming, and web development.
