Difference Between Class and Structure in C#

In the programming world, class and structure both play an imperative role. A class is like a model from which objects are created. While the structure is also a user-defined model that holds a set of data types. Let’s analyze some major differences between Class and Structure in C#.

What Is Class?

A class is like a model from which objects are created. It mainly combines the methods and fields into a sole unit.

What Is Structure?

The structure is also a user-defined model or data type, and exactly like the class, it tends to hold a set of data types. Or in other words, we can say that structure is a group of variables of various data types under a sole unit.
