Introduction: In the previous article , Chapter 6.1, we discussed the System.IO namespace, which provides classes for working with files, directories, and streams. In this article, we'll explore the System.Text and System.Text.Encoding namespaces, which are important for working with text and character encodings in C# applications. In the next article, we'll discuss the System.Collections and System.Collections.Generic namespaces, which are essential for working with collections of objects. System.Text Namespace: The System.Text namespace contains classes and interfaces for working with text and character encodings. Some key classes include: StringBuilder: Provides a mutable string buffer for efficient string manipulation. Encoding: Represents a character encoding, such as UTF-8, UTF-16, or UTF-32. Decoder/Encoder: Convert between different character encodings and byte arrays. StringBuilder: The StringBuilder class is useful for efficient string manipula...

 Introduction: In this new chapter, we'll explore working with .NET classes, which are essential for developing robust and efficient C# applications. In this first article, we'll discuss the System.IO namespace, which provides classes for working with files, directories, and streams. In the next article, we'll delve into the System.Text and System.Text.Encoding namespaces, which are important for working with text and character encodings. System.IO Namespace: The System.IO namespace contains classes for performing various operations on files, directories, and streams. Some key classes include: File: Provides static methods for creating, copying, deleting, and moving files, as well as opening files for reading and writing. Directory: Provides static methods for creating, deleting, and moving directories, and enumerating files and directories. FileStream: Represents a file stream, allowing you to read and write data to a file. StreamReader/StreamWriter:...

 Introduction: In the previous article , Chapter 5.1, we discussed reading and writing text and binary files, essential skills for working with data in C#. In this article, we'll explore serialization and deserialization of objects, which are important for persisting and restoring object states. In the next article, we'll discuss working with .NET classes, an important aspect of developing C# applications. Serialization: Serialization is the process of converting an object's state into a format that can be stored or transmitted. In C#, the .NET framework provides several serialization mechanisms, such as binary, XML, and JSON serialization: // Binary Serialization BinaryFormatter formatter = new BinaryFormatter(); using (FileStream stream = new FileStream( "data.bin" , FileMode.Create)) { formatter.Serialize(stream, myObject); } Deserialization: Deserialization is the process of reconstructing an object's state from a serialized forma...

 Introduction: In this new chapter, we'll explore File I/O and Serialization, essential concepts for working with data in C#. In this first article, we'll discuss reading and writing text and binary files. In the next article, we'll delve into serialization and deserialization of objects, which are important for persisting and restoring object states. Reading and Writing Text Files: C# provides several classes for reading and writing text files, such as StreamReader, StreamWriter, and File: // Writing a text file using (StreamWriter writer = new StreamWriter( "example.txt" )) { writer.WriteLine( "Hello, world!" ); } // Reading a text file using (StreamReader reader = new StreamReader( "example.txt" )) { string line; while ((line = reader.ReadLine()) != null ) { Console.WriteLine(line); } } Reading and Writing Binary Files: For working with binary files, C# provides the BinaryReader and Bina...

 Introduction: In the previous article , Chapter 4.2, we explored heap and stack memory, which are crucial for understanding how memory is allocated and managed in a C# program. In this article, we'll delve into garbage collection and finalization, essential concepts for managing memory resources efficiently in a C# application. In the next article, we'll discuss file I/O and serialization, another important aspect of working with data in C#. Garbage Collection: Garbage collection is the process of automatically reclaiming memory that is no longer in use. The garbage collector (GC) is responsible for managing heap memory, identifying objects that are no longer accessible, and deallocating their memory. This helps prevent memory leaks and ensures that your application uses memory efficiently: Person person = new Person( "John" , "Doe" ); // Memory allocated on the heap person = null ; // Now eligible for garbage collection Generations: Th...

 Introduction: In the previous article , Chapter 4.1, we discussed the differences between reference and value types. In this article, we'll explore heap and stack memory, which are crucial for understanding how memory is allocated and managed in a C# program. This topic is of great importance, so we'll cover it in detail. In the next article, we'll discuss garbage collection and finalization, which are essential for managing memory resources efficiently in a C# application. Heap Memory: Heap memory is a region of memory where objects are dynamically allocated during the runtime of a program. When you create an instance of a reference type, memory is allocated on the heap. Heap memory is managed by the garbage collector, which automatically reclaims memory that is no longer in use: Person person = new Person( "John" , "Doe" ); // Memory allocated on the heap Stack Memory: Stack memory is a region of memory where value types and method...

 Introduction: In this new chapter, we'll focus on memory management and garbage collection, which are essential for understanding how resources are managed in a C# application. In this first article, we'll explore the differences between reference and value types. In the next article, we'll discuss heap and stack memory, which are crucial for understanding how memory is allocated and managed in a C# program. Reference Types: Reference types store a reference to the memory location where the data is stored. When you create an instance of a reference type, the memory is allocated on the heap. Classes, interfaces, delegates, and arrays are examples of reference types: Person person1 = new Person( "John" , "Doe" ); Person person2 = person1; person2.FirstName = "Jane" ; Console.WriteLine(person1.FirstName); // Output: Jane Value Types: Value types store the actual data, and when you create an instance of a value type, the memo...
