Properties

1. Provides encapsulation, enabling code maintainability and bug fixing.
2. Data binding classes in .net supports properties but not variables.
3. Adding multi-threaded support is much easier.
4. Can be extended in interfaces.
5. One of the accessors can be have a different visibility.
6. Supports of parameterized properties (indexers).
7. Changing public data members to Properties at a later stage will break binary compatibility. So it’s better to start right.
