What are the best practices for implementing GetHashCode in C#?
When implementing GetHashCode in C#, ensure that it is consistent with Equals, use prime numbers, and consider performance.
Can you explain why it's important for GetHashCode to be consistent with Equals?
Yes, if two objects are considered equal by Equals, they must return the same hash code. This is crucial for hash-based collections.
What are some common pitfalls to avoid when implementing GetHashCode?
Common pitfalls include using mutable fields, not considering all relevant fields, and returning constant hash codes.
Are there any tools or libraries that can help with generating GetHashCode implementations?
Yes, tools like ReSharper can help generate GetHashCode implementations based on your class properties.
