C#.NET — Object-Oriented way to handle run-time errors: choose the correct mechanism.

Introduction / Context:
Object-Oriented languages, including C#, use a structured mechanism for error handling that integrates with control flow and type hierarchies.

Given Data / Assumptions:

• We compare legacy or C-style techniques with OO approaches.

Concept / Approach:
Exceptions provide a type-safe, structured way to signal and handle run-time errors using try/catch/finally blocks, enabling separation of error detection and error handling logic.

Step-by-Step Solution:

Verification / Alternative check:
In C#, throwing and catching Exception-derived types is the standard approach endorsed by the framework.

Why Other Options Are Wrong:
They are not idiomatic in C# or are legacy/non-OO techniques.

Common Pitfalls:
Overusing exceptions for normal control flow or swallowing exceptions without logging.

Final Answer:
Exceptions
