Chapter 4.3: Memory Management and Garbage Collection: Understanding Garbage Collection and Finalization

 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

Chapter 4.2: Memory Management and Garbage Collection: Understanding Heap and Stack Memory

 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

Chapter 4.1: Memory Management and Garbage Collection: Understanding Reference and Value Types

 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
