Exposing public fields or collections in C# can lead to invalid state, broken invariants, and hard-to-find bugs. This article shows why direct access is dangerous, how to encapsulate collections safely, and when public fields are acceptable. Includes practical code samples and actionable advice for writing robust, maintainable C# code.
Discover why exposing behavior instead of data is a core principle of robust C# design. See practical examples of leaky vs encapsulated classes, learn how to protect invariants, and get actionable tips for writing maintainable, future-proof APIs.
Discover why private fields are crucial for safe, maintainable C# code. See the dangers of public fields, how private fields enable validation and business logic, and get actionable tips for robust object design with real-world examples.
