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.
Difference Between Class and Structure in C#
| S.No. | Class | Structure |
| 1. | The reference types are placed on local stack memory. | The value types are placed on stack memory. |
| 2. | They are considered as reference types. | They are considered as value types. |
| 3. | In class, the allocation of large reference types is more affordable than the allocation of large value types. | In structure, the allocation is more affordable in value than the reference type. |
| 4. | It is usually applied in large programs. | It is usually applied in small programs. |
| 5. | It comprises many features. | It has restricted features. |
| 6. | It can include constructors or destructors. | It cannot contain constructors or destructors. |
| 7. | Classes can create an instance by using the keywords. | Structures don’t need keywords for creating an instance, without a new keyword. |
| 8. | A Class can derive from another class. | A structure cannot inherit from another class or structure. |
| 9. | In the case of class, the data member can be guarded. | In the case of structure, data members cannot be protected. |
