In C#, a structure is a value type data type. It helps you to make a single variable hold related data of various data types. The struct keyword is used for creating a structure.
When you define a class, you define a blueprint for a data type.
The following are the differences between classes and structures in C# −
Classes are reference types and structs are value types
Unlike classes, structures cannot inherit other structures or classes.
Structures cannot be used as a base for other structures or classes.
When you create a struct object using the New operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the New operator.
Structures do not support inheritance
Structures cannot have a default constructor
