Welcome to the C# Mastery: Coding and Conceptual Practice Test, designed for developers and students who want to deepen their knowledge of C# programming. This practice exam-based course focuses on the core principles, advanced topics, and practical coding scenarios that are essential for both real-world applications and technical interviews. Whether you’re preparing for a job interview or refining your C# skills, this course will provide the perfect platform to practice and test your understanding.
Each section is meticulously structured to cover the most important topics in C#. You’ll encounter a variety of question types, including multiple-choice, multiple selection, true/false, and coding-based problems. 50% of the questions are coding-based to test your practical implementation skills. The course is broken down into six detailed sections:
Section 1: C# Fundamentals and Syntax
Topics Covered:
-
Basic Syntax and Structure
Understanding the basic syntax of C#, including the use of namespaces, classes, methods, and main structures like loops, conditionals, and variables. -
Data Types and Variables
Covers value types, reference types, and variable declarations. Explores primitive data types like int, string, bool, and user-defined types. -
Operators and Expressions
Discusses arithmetic operators, relational operators, logical operators, and bitwise operators. Focuses on how expressions are evaluated in C#. -
Control Flow Statements
Introduces if-else statements, switch cases, and different types of loops (for, while, do-while). Learn about break and continue statements. -
Error Handling (Exceptions)
Understanding try, catch, finally blocks for error handling. Discusses common exceptions and best practices for robust error handling.
Section 2: Object-Oriented Programming (OOP) in C#
Topics Covered:
-
Classes and Objects
Learn about the creation and manipulation of classes and objects, including constructors, methods, and object instantiation. -
Encapsulation
Discusses the concept of encapsulation, using access modifiers (public, private, protected) and properties to control access to class members. -
Inheritance and Polymorphism
Focuses on reusability and how derived classes inherit from base classes. Covers polymorphism with method overriding and method overloading. -
Abstraction
Introduces abstract classes and interfaces, and the role they play in creating flexible and maintainable code architectures. -
Interfaces and Abstract Classes
Understand the differences between interfaces and abstract classes, and learn when to use each.
Section 3: Data Structures and Algorithms
Topics Covered:
-
Arrays and Lists
Learn how to work with arrays, lists, and other collection types in C#. Understand the differences between fixed-size arrays and dynamic collections. -
Stacks and Queues
Covers stack and queue data structures, their implementations, and use cases in various programming scenarios. -
Linked Lists
Learn about singly and doubly linked lists and their applications. Topics include traversing, inserting, and deleting nodes. -
Dictionaries and Hash Tables
Understand how hash tables and dictionaries work for fast lookups. Covers collision handling and performance optimization. -
Sorting and Searching Algorithms
Delves into common algorithms such as Bubble Sort, Merge Sort, and Binary Search, with an emphasis on algorithm efficiency and time complexity.
Section 4: Multithreading and Asynchronous Programming
Topics Covered:
-
Threads and Threading in C#
Understand how threads work in C#, how to create and manage them, and common challenges such as race conditions and deadlocks. -
The Task Parallel Library (TPL)
Explore TPL for handling parallelism in C#. Learn how to use tasks to run operations asynchronously and in parallel. -
Async and Await
Discusses the async/await pattern for writing non-blocking code. Focuses on best practices for managing long-running tasks. -
Synchronization Mechanisms
Covers thread synchronization techniques, including locks, semaphores, and monitors to prevent concurrency issues. -
Cancellation Tokens
Learn how to handle task cancellation using cancellation tokens, allowing greater control over long-running operations.
Section 5: Advanced C# Concepts
Topics Covered:
-
Delegates and Events
Learn how to use delegates and events to create flexible, extensible programs. Understand multicast delegates and event handling. -
Lambdas and Anonymous Functions
Discover how lambda expressions and anonymous functions are used for more concise and readable code. -
LINQ (Language Integrated Query)
Understand how LINQ can simplify data querying in C#. Covers both query and method syntax, including filtering, projection, and aggregation. -
Extension Methods
Learn how to use extension methods to add functionality to existing classes without modifying their original structure. -
Reflection
Covers reflection in C# for inspecting assemblies and types at runtime. Learn how it’s used for dynamic type creation and metadata access.
Section 6: Memory Management and Design Patterns
Topics Covered:
-
Garbage Collection
Learn about C#’s automatic memory management through garbage collection, including the three generations of objects. -
Dispose Pattern and IDisposable
Understand how to release unmanaged resources explicitly using the Dispose method and implement the IDisposable interface. -
Design Patterns (Singleton, Factory, Prototype, etc.)
Explore common design patterns such as Singleton, Factory, and Prototype, and how they can be implemented in C# for cleaner, more maintainable code. -
Weak References and Memory Optimization
Learn about weak references and how they help prevent memory leaks by allowing garbage collection of objects no longer in use. -
Common Memory Pitfalls and Best Practices
Avoid common memory issues such as memory leaks, inefficient resource management, and improper disposal of resources.
