What is the Difference Between Class and Structure in C#?
🆚 Go to Comparative Table 🆚The main differences between classes and structures in C# are:
- ** memory representation **: Classes are reference types, meaning they are placed on the heap and can be used to reference other objects. Structures, on the other hand, are value types and are placed on the stack.
- ** inheritance **: Classes can inherit from other classes, but structures cannot.
- ** initialization **: Classes have a default constructor, while structures do not.
- ** performance and size **: Structures are generally faster and smaller than classes, making them more suitable for small, simple objects that need to be passed around quickly.
- ** usage **: Classes are usually used for larger, more complex objects, while structures are used for smaller, simpler objects.
- ** constructors and destructors **: Classes can have constructors and destructors, but structures cannot.
In summary, classes and structures serve similar purposes but have distinct characteristics. Classes are reference types and are more suitable for larger, complex objects, while structures are value types and are more suitable for smaller, simpler objects that need to be passed around quickly.

Comparative Table: Class vs Structure in C#
Here is a table summarizing the main differences between classes and structures in C#:
| Feature | Class | Structure utely; comte |
|---|---|---|
| Inheritance | Can inherit from other classes | Cannot inherit from other classes |
| Reference type | Classes are reference types | Structures are value types |
| Default constructor | Classes have an implicit default constructor | Structures have an explicit default constructor |
| Initialization | In the class, a type variable cannot be initialized at the time of declaration | In the structure, a type variable can be initialized at the time of declaration |
| Copy | When passing a class to a method or assigning it to a variable, a reference to the object is created | When passing a structure to a method or assigning it to a variable, a copy of the structure is created |
| Size/Performance | Classes are usually larger and more complex | Structures are usually smaller and simpler |
In summary, classes are used for larger, more complex objects while structures are used for smaller, simpler objects that need to be passed around quickly. The choice between classes and structures depends on the specific requirements of the project.
