Introduction: Welcome to the next chapter of our C# learning series! In this chapter, we'll dive into advanced C# concepts to further enhance your understanding of the language. In this article, we'll discuss LINQ and lambda expressions, two powerful features that simplify data manipulation and make your code more expressive. In the next article, we'll explore exceptions and debugging, essential techniques for building robust and reliable applications. LINQ (Language Integrated Query): LINQ is a set of features in C# that allows you to perform complex data queries directly in the language, without having to use SQL or another query language. LINQ can be used with various data sources, such as arrays, collections, XML, and databases. It provides a consistent query syntax, making it easier to work with different types of data: int [] numbers = { 2, 5, 1, 6, 8, 3, 7 }; var evenNumbers = from number in numbers where number % 2 == 0 ...

 Introduction: In the previous article , Chapter 3.3, we discussed generics and anonymous types, important concepts for creating flexible and reusable code. In this article, we'll explore reflection and dynamic programming, powerful techniques for working with types and objects at runtime. In the next topic, we'll dive into memory management and garbage collection, which are essential for understanding how resources are managed in a C# application. Reflection: Reflection is a feature in C# that allows you to inspect and interact with the metadata of types, objects, and assemblies at runtime. You can use reflection to create instances of types, invoke methods, get and set property values, and more: Type personType = typeof (Person); MethodInfo methodInfo = personType.GetMethod( "SayHello" ); object [] parameters = new object [] { "John" }; string result = ( string )methodInfo.Invoke( null , parameters); Console.WriteLine(result); Dynamic...

 Introduction: In the previous article , Chapter 3.2, we discussed exceptions and debugging, essential techniques for building robust and reliable applications. In this article, we'll explore generics and anonymous types, which are important concepts for creating flexible and reusable code. In the next chapter, we'll dive into reflection and dynamic programming, powerful techniques for working with types and objects at runtime. Generics: Generics allow you to create classes, methods, and interfaces that can work with different types without sacrificing type safety. By using generics, you can create reusable and type-safe code without the need for casting or boxing: public class GenericList <T> { private T[] data; private int count; public GenericList( int size) { data = new T[size]; count = 0; } public void Add(T item) { data[count++] = item; } public T Get( int index) { retur...

 Introduction: In our previous article , Chapter 3.1, we explored LINQ and lambda expressions, which are powerful tools for simplifying data manipulation and making your code more expressive. In this article, we'll discuss exceptions and debugging, essential techniques for building robust and reliable applications. In the next chapter, we'll dive into generics and anonymous types, which are important concepts for creating flexible and reusable code. Exceptions: Exceptions are events that occur during the execution of a program when an error or an exceptional condition occurs. They can be caught and handled using try-catch-finally blocks. The try block contains the code that may throw an exception, the catch block contains the code to handle the exception, and the finally block contains code that will always be executed, regardless of whether an exception was thrown or not: try { int result = 10 / 0; } catch (DivideByZeroException ex) { Console.WriteLine( ...
