Difference between Class and Interface in C#

In C#, a class is a blueprint that defines the data and behavior of objects, while an interface is a contract that defines the capabilities that a class must implement.

Classes can contain fields, properties, methods, constructors, and events, while interfaces only declare methods, properties, indexers, and events without providing implementation.

Classes support inheritance and can be instantiated, while interfaces support multiple inheritance and can be implemented by classes to provide specific functionalities.

Overall, classes are concrete implementations, whereas interfaces are abstract definitions that enforce a consistent structure across different classes.
