C# Mastering Course For Intermediates

Learn how a C# method is a reusable block of code that may accept parameters, is called to execute, and can return a value or be void.

Learn how to call a method in C# by defining a simple method in a console app, passing parameters, and understanding control flow and output.

Define parameters as variables inside a method to customize results, and pass values or variables as arguments to a method, ensuring the number and types align with declared parameters.

Learn how C# methods return values with appropriate return types, use return statements, and handle void methods, including examples of multiplying two numbers and using results in later calculations.

Learn how constructors initialize fields in a C# class, including default and overloaded variants. Use this dot notation to assign values and explore access modifiers for private fields.

Explore how encapsulation in C# uses private fields and public properties to read or update values, replacing constructors for ongoing modifications and protecting data.

Learn how automatic properties in C# provide a field-free property through a concise get and set syntax, enabling public access and default zero values for numeric types.

Learn to apply get and set access modifiers in C# to control read and write access for properties, using private set and selective getters inside and outside the class.

Learn how to implement abstraction in C# by defining an abstract shape with abstract area and perimeter, then create square and rectangle subclasses that override these methods.

Explore how interfaces enable multiple inheritance in C#, implement interface members in classes, and use this pattern to compose behavior beyond single-class inheritance in C#.

Explore how sealed classes and sealed methods prevent inheritance and overriding in C#, with examples from animal, bird, and chicken to illustrate when to apply them.

Learn how to throw and customize exceptions in C# by creating custom exception classes, using not implemented exceptions, and handling them with try-catch blocks while implementing interfaces.

Learn debugging techniques in C# by tracing logical errors with breakpoints, the watch window, and step operations, fix withdrawals and balance calculations, and verify outputs in the console.
