Sure, let's dive into the basics of structs in C#. Structs, or structures, are value types in C#, which means they hold the data in their own memory space. This is opposed to reference types, which store a reference to the value's memory space. The main difference is that changing a struct does not change another struct, whereas changing an object can change other referenced objects. Here's a basic declaration of a struct: ```C# public struct Book { public string title; public string author; public int pages; } ``` To instantiate a `Book` struct, you would do the following: ```C# Book myBook; myBook.title = "Awesome Book"; myBook.author = "An Awesome Author"; myBook.pages = 300; ``` You can also define constructors, methods, and properties within a struct. Structs can't be null, handlers to events in a struct can't be removed or added (except by the struct itself), and a struct can't be the direct or indirect parent class of another struct or class. Benefits of using structs can include improved performance when dealing with small data structures that have value semantics. Keep in mind that structs should be used wisely. If your data should not be mutable, a struct might not be the best choice. Similarly, for larger data structures, using a class might be a better option. Remember that structs in C# are different from structs in C++. Unlike C++, C# does not allow a struct to inherit from another struct or class, and it cannot be the base of a class. A struct can implement interfaces, but it does not support inheritance.
