Mastering C# Structs: Lightweight and Efficient Data Structures

The blog titled "C# Structures (Structs)" is a comprehensive guide to understanding and using structs in C#. The article starts by defining what a struct is and how it differs from a class. It then goes on to explain the various features and advantages of using structs in C#.

A struct is a value type that can contain variables, methods, and constructors, just like a class. However, unlike a class, a struct is a lightweight object that does not require the use of the garbage collector. This makes structs a great choice for storing small amounts of data that need to be passed around quickly and efficiently.

The article then explains the syntax for creating a struct and the various members that can be defined inside a struct. Members can be variables, methods, properties, and events. The author also explains how to initialize a struct and how to pass a struct as a parameter to a method.

One of the advantages of using structs is that they are more memory efficient than classes. This is because structs are stored on the stack, whereas classes are stored on the heap. The article provides a helpful example to illustrate this point. In the example, the author creates a struct that contains two variables, and then creates an array of 10,000 instances of the struct. The memory used by the struct array is only 20KB, whereas an array of 10,000 class instances would require significantly more memory.

Another advantage of using structs is that they can be used to create custom data types. The article provides an example of creating a Point struct that contains two variables for X and Y coordinates. The author then shows how to use this Point struct to create a custom data type for representing a rectangle.

The article also explains the differences between structs and classes in terms of inheritance, default values, and copying. For example, structs do not support inheritance, and they have default values for their members, whereas classes do not. The author also explains how to copy structs using the copy constructor.

Overall, the "C# Structures (Structs)" blog provides a thorough introduction to the topic of structs in C#. It explains the syntax for creating a struct, the various members that can be defined inside a struct, and the advantages of using structs over classes. The author provides helpful examples to illustrate these concepts and also explains the differences between structs and classes in terms of inheritance, default values, and copying. Anyone who is new to C# or who wants to learn more about structs should find this blog to be a helpful resource.
