struct (C# Reference)

A struct type is a value type that is typically used to encapsulate small groups of related variables, such as the coordinates of a rectangle or the characteristics of an item in an inventory. The following example shows a simple struct declaration:

public struct Book
    public decimal price;
    public string title;
    public string author;

Structs can also contain constructors, constants, fields, methods, properties, indexers, operators, events, and nested types, although if several such members are required, you should consider making your type a class instead.

Structs can implement an interface but they cannot inherit from another struct. For that reason, struct members cannot be declared as protected.
